How to connect the oven and hob

Connection of the hob and oven to the mains

It is already difficult to imagine a modern kitchen without electric furnaces and a built.In hob. This is a good way to optimize the ergonomics of the room and improve the interior. The main number of users have the difficulties of connecting such a technique to electricity. To connect the oven is enough ordinary euro.Outlet. But the hob, due to its potential and energy consumption, is joined through an auxiliary electric connector, withstanding high voltage. How to connect a hob and oven, if two different forks are not suitable for one outlet?

Electric stoves and electric admirations are not considered energy economic (2–9 kW). Therefore, according to the conditions of safe use, it is necessary to take an auxiliary outlet for the hob and for the oven from the machine gun. At the same time, if the electric stove and the electric drill are designed for separate connection to the mains, you need to put additional sockets with additional circuit breakers on the electrical panel.

Joining a standard outlet allotted for the power supply of a teapot or any household appliance is possible provided that the electric shower is up to 3 kW; if a copper three.Bottom cable was used during the installation of a socket; Replacing a standard circuit breaker in different with a current up to 15 A.

In many apartments, one automatic machine is installed for the entire complex of outlets 15–25 A, and additional. This can lead to the fact that when replacing at least one machine gun of the Roset complex with the various, to which the device is connected, it will be impossible to use the rest of the devices during the operation of the electrical admission.

Think well before the transition to this connection method. Weigh what is better: spend on new wiring, outlet and sleep calmly or save. Leave a regular machine in the shield when installing the oven on an old outlet is undesirable.

The power of the electric oven and the hob

Electric oven

Oven and the hob that consumes a large amount of electric energy during operation. The exact indicators depend on the device model and indicate on the package to it (usually on a special sticker on the device from below and in the instructions on the first page). Most devices of this type have the following power:

To withstand a similar level of load, it is necessary to choose the corresponding cable, since in the case of the use of too thin wires, the wiring will very quickly burn out. In practice, the oven and the hob are connected through a separate fishing line for a trimmer with a machine gun directly to the electric shield. This avoids overload, and in case of improper operation of the device, you can quickly de.Energize by turning off the machine.

Note! Watt and kilowatt are binded by a simple ratio: 1 kilowatts (kW) = 1000 watts (W).

Installation of the oven of the built.In

Connection of the oven begins with the preparation of the niche for its location. It is necessary that there are no distortions (we use the level to control this moment), otherwise the device may quickly break due to the improper distribution of heat.

Before installing the oven with your own hands, you need to prepare a place for work in advance. First of all, a niche where it will be installed. It is important to make sure that there are not the slightest distortions here. To do this, use the level.

If you allow at least a slight skew, the device can fail after a few years of operation. Heat will be distributed incorrectly and unevenly, which will damage thin electronics.

When the built.In oven works, a large amount of heat is released. Its accumulation can lead to a variety of problems. The product itself may fail from overheating.

Even worse, if a wooden cabinet shuts up, and then lights up. This will lead to a real fire. Therefore, in order to install such a technique on your own, you need to carefully calculate every step.

The risk of overheating and fire will be zero if you properly place the closet in the niche before connecting it to the network.

    Experts set such a distance from its walls to the edges of the niche:

With this distance, high.Quality ventilation is provided, completely eliminating the risk of technology overheating.

Features of the installation

Electrical equipment is much simpler, and therefore it is preferable to install with your own hands. However, it is also important here to properly install, since a short circuit can become as fatal as a gas leak.

As a rule, manufacturers of kitchen sets and built.In equipment adhere to uniform standards, so there should be no problems. But checking the roulette correspondence of the size before connecting the oven will be useful.

Connecting an electric oven is much easier than a gas. Therefore, many people decide to perform this work on their own without overpaying to specialists.

connect, oven

Yes, there are no hoses along which gas is coming, but still you can’t relax, forgetting about the elementary rules of electrical safety. After all, one mistake is enough for a short circuit that may well lead to a fire.

First of all, you need to seriously approach the network cabinet. The electric oven is a very powerful household appliance. Therefore, to connect it, it is necessary to use a separate branch of the wire.

Over, its section should be at least 2.5 squares. Throughout the wire should not be twisted (even very high-quality connected) and any other damage. Otherwise, the danger of short circuit increases sharply.

A branch intended to ensure the energy supply of the oven, it is necessary to equip the circuit breaker. The power is calculated for a specific model, depending on the strength of the current consumed during the operation of the oven.

In most cases, this number lies in the range from 16 to 20 amperes. In cases where the electrical hob is connected together with the oven, you should choose the machine, taking into account the total power consumption.

Grounding is an obligatory attribute of a modern oven cabinet. Only it allows you to ensure complete safety of working with an electric oven. If we are talking about a private house, then there are no problems here. In apartments, especially old ones, with this is much more difficult. The wiring simply does not provide grounding.

It is better to entrust this work to specialists. If you decide to connect the oven with your own hands, you need to stretch an additional wire from the kitchen to a common shield on the landing and connect it to a suitable metal object.

Only if all the work is done correctly and accurately, you can guarantee the safe operation of a new oven cabinet.

Safety regulations

Caution should be shown during the preparation of the electrical wiring, and when the actual or built.In oven is actually connected. First of all, this concerns personal safety.

Since the electric oven is characterized by high energy consumption, it will need to be carried out by an additional branch using an intact wire with a section of a current.For.Bonding of about 2.5 or 4 kV. Mm, if you came across an oven with a capacity of more than 3.5 kW.

Connect a live core through a separate machine, to which you can throw an electric hob of. The characteristics of automatic protection are selected depending on all the loads coming on it with a 10%margin.

So that the further operation of the electric oven is safe, you will need to correctly mount the grounding. This is not a problem in your house. But in the apartment buildings of the old building, a separate core will need to independently ground on the tire of the general electrical panel.

If we are talking about a technique of relatively low power up to 3 kW, and the wiring in the house is reliable and designed for modern loads, the use of standard Euro.Zoomers is allowed to install oven cabinets.

Installation work

If there was no factory fork on the wire of the device, it can be placed yourself. You will need a fork of the euro sample with a ground plate. The corresponding core of the cable will be connected to it (usually it has a green or yellow braid). The remaining two wires are tightly pressed by terminals to brass contacts.

To the power cable supplied from the distribution box according to the same scheme, the socket is connected under the oven.

Some oven do not even have wires for inclusion in the network. In this case, it will need to be purchased and mounted on the corresponding terminals.

For work, the VVG wire will be required (if the sections of the veins are at 2.4 kV. Mm is enough) or PVS. Such a length so that it can be pulled from the oven to the nearest camshaft.

How to connect an electric oven and a hob (electric stove)

ELECTRIC COOKER WIRING

Electric stoves (hobs) and electric oven are often used in home kitchen. In this case, the choice of type of plate does not depend on the presence of gas in the house. However, these are powerful electrical appliances and you need to follow the recommendations for their connection. It is worth considering that the wiring should be designed for the food of these consumers in order to avoid emergency situations. In this article we will talk about the intricacies of connecting to the kitchen electrical equipment network.

If you are installed in you an electric oven and the hob first of all you need to decide on the models and recommendations of manufacturers. What to pay attention to when connecting:

In some cases, the electric stove and the oven are connected independently of each other, but if it is models from the set of one manufacturer, you need to look in the instructions, perhaps they should be interconnected.

Connecting the cord to the electric stove, depending on the manufacturer, the cord can be removable or inexpressible. In models with a built.In cord, they are found in Bosch, there is no way to replace it, it is fixed in an electric stove, if you need to lengthen it. You will have to cut and connect using terminals, sleeves or in another way.

Connection to the mains

Typically, household outlets withstand currents up to 16A, this current consumes devices with a capacity of up to 3.5 kW. Therefore, if the power of your plate and electric attitude is included in this range, then you can connect to the outlet.

Powerful slabs may require the presence of three.Phase input, if this is not, you have to get out of the situation by changing the connection of heating elements, turning on everything in parallel. Then the power is most likely to be over 3.5 kW. Then you need to connect the wires directly to the machine with current up to 32a. It is selected in accordance with the real consumption and a small margin (20-40% will be more than enough), an circuit breaker with labeling type C32 is suitable.

It is worth noting that there are plugs for 32a, they are quite large in size, and their pins are unusual round, and rectangular. They are connected as follows:

On the case of the device or in the instructions, the connection diagram for different phases and voltage value should be indicated. Like this:

Please note that each of the contacts is numbered, and the diagram indicates where the jumpers are installed.

In the lower or upper part on the back, there is usually a window through which the connection is performed.

Jumpers can be installed before you, in accordance with the common type of networks in a particular region. Pay attention to the photo, the copper jumpers of the factory manufacturing, similar to the tires, are already installed under the wires, but it is better to verify once again.

For example, in the photo, each of the terminals is numbered. If there were no such jumpers. Make them with your own hands from pieces of wire. In the photo, the wires are connected directly to the terminals, but it is better to do this using round terminals (cable tips).

In the kitchen, especially near the stove, usually hot and humid, it exacerbates the functioning of both cables and the devices themselves. Hence the increased danger of electric shock damage.

In any case, the connection should be performed through the RCD, and the case is extremely desirable to ground.

To connect an electric hob and oven, you can use both flexible cables and monolithic, for example, 3×2 VVG.5 and other suitable.

Do not connect the former cable. How to choose the exact section of the cable for a specific load on the site an article was previously published.

The connection diagram of the electric stove through the RCD and the machine to a single.Phase and three.Phase power supply is shown below:

What can not be done when connecting an electric stove: tips and recommendations

If during the repair in the kitchen you have not provided for the replacement of the wiring, you must clearly realize that the old aluminum cables are not intended for such loads, even if electric stoves and oven were also installed earlier. It is recommended to use copper so as not to lay a cable in the wall after completing finishing work can be laid out to external methods, for example, in the channel cable.

A fishing line for a trimmer should go directly from an introductory machine and only an electric stove and an oven are connected to it.

You can not connect to one outlet through tees or extensors of the slab and oven at the same time-something will definitely fail.

If you connect an old electric stove again, replace the fork, it is probably an old.Sample and has already worn out. This will not take time or financial resources, but will improve contact and reduce the heating of the outlet, and this will save you from problems in the future.

Built.In models are very popular now. They fit perfectly into the set of kitchen furniture, but you need to consider the dimensions so that everything is fine. It is worth saying that just to shove an electric oven instead of a kitchen bedside table will not work. It is necessary to withstand small tolerances for the normal functioning of the devices. They also perform ventilation roles, cooling the body.

The picture below shows approximate sizes:

Distance from the bottom of the oven to the floor-5-8 cm;

From the side panels of the housing and kitchen furniture. 5 cm;

How to connect an oven to a power supply correctly. What wire and assault machine need?

To connect the oven with a maximum power of not more than 3.5 kW, you must have the following materials in stock:

  • 3-residential cable VVGNG-LS 32.5mm2
  • Ordinary euro.Rosette at 16a, with contacts under the grounding conductor
  • Fork at 16A. It is preferably angular in order to take less space between the posterior wall of the kitchen and the wall of the kitchen room.
  • Diffavtomat on 16a, or RCD of Diffavtomat

The oven of an electric cabinet should always be connected through its separate machine. He can stand either in the distribution or in the immediate vicinity of the electrical appliance (more on that below).

If you have an apartment at the repair stage, then start working with strokes of the walls and laying the VVGNG-LS 32.5 cable from the electrical panel to the future outlet. If the repair is already made, then the cable can be laid in a plastic channel or a decorative skirting board without spoiling the wallpaper.

Many have a question, whether it is possible to connect an electric oven from an existing ordinary outlet, which was previously installed in the kitchen for a teapot, microwave, etc.P.?

How to install your Electrolux Oven with Hob. Built Under installation

It is possible, the main thing is that 3 conditions are met at the same time:

  • The oven should be a power of not more than 3.5 kW
  • The outlet is connected by a three.Core copper cable from the shield with a cross section of at least 2.5 mm22
  • In electrical panel, replace a regular machine with a thermal release with a differential machine with a nominal current of not more than 16A

According to the third condition, some may have inconvenience and small problems. As a rule, many still have one automatic machine for 16A-25A for the entire outlet group, plus one more on lighting.

When replacing a single machine for sockets with differential 16a and connecting the oven through it, it will not be possible to use other electrical appliances while the oven works and food is prepared.

Here you will already have to make a choice yourself, or in favor of savings (not to lay out new wiring, a separate outlet, etc.D.), or in favor of comfort and convenience.

Leave in the shield an ordinary modular machine without protection from leakage currents, when connecting an oven to an old outlet, is not recommended.

The height of the installation of a new outlet under the oven should be no more than 90 cm from the floor. Although it is also not rarely put at the level of the legs of the kitchen.

The most important thing here is the convenience of operation. By safety precautions, with wet cleaning and wiping the oven with a wet rag, it must be disconnected from the mains.

And climbing every time to the bottom of the kitchen to pull the fork is not always convenient. In addition, here you need to take into account such possible situations as leakage of water and flooding of the kitchen. Therefore, 5-10cm above the floor, the outlet should still be raised.

Another moment in safety precautions when installing a socket: if a gas supply passes nearby, for example, on a hob (let’s say it is gas rather than electric), then the outlet should be at least 60 cm from it at a distance.

When the outlet was determined with the location of the socket, it is necessary to connect it.

The phase and zero core of the cable connect to the extreme contacts of the outlet. At the same time, it does not matter where the phase will be located, and where zero is on the right or on the left. The grounding core (yellow-green) connect to the ground terminal (usually average).

Put in place a frame or decorative cover.

If the oven goes with a factory fork, then it may not be collapsible, but whole cast. And then her cutting offers the loss of guarantee, be careful in this matter.

But as a rule, in the latest models with a oven, there is no installation fork, so you also need to connect it yourself.

This is explained by the fact that in different countries, the oven can be connected to at least several types of completely different sockets.

And guessing the manufacturer which fork where you need, is simply not profitable.

You clean the wire from the oven, criminalize the NShV tips and pass through the plug body. Phase and zero (usually the conductors of gray = brown and blue colors) Plant the plugs of the extreme contacts.

Again, no matter where what, phasing here is not important here. Yellow-green grounding core-for average contact. So that the wire does not dangle inside, fix it with a pushing clamp and twist the plug body.

A little theory

Consider the power formula for the case when the voltage in the 220V outlet connecting these values:

The letter P is the power (in fact, in the passport or sticker on the oven panel or hobs, the number to the letter W, indicate the power), I is the value of the current consumed (then it will become clear what this value is important), U is the network voltage (220 V), cosφ. Power coefficient (equal to 0.95).

Thus, the oven current (at p = 3.5 kW, according to formula 1) is 16.7a, hob (at p = 7.2 kW, according to Formula 1) equal to 34a.

The electrical network of the apartment (houses) is protected from emergency cases (such as short circuit, overload) using circuit breakers (machines) and/or differential circuit breakers (definitely not an RCD).

When we approach the meter of electricity to write down the readings, we see mainly the same picture. This is circuit breakers.

The size of the circuit breakers is characterized by the maximum operation current. Say, new buildings use automation 16a (16 amperes), 32a, 40a, an introductory machine on average 50a.

Knowing all this, we will try to understand how we correctly connect to the mains.

So repairs are made. Think about the fact that the kitchen will not be an electric stove, but an oven and a hob, follows at the stage of designing a housing electric network. First of all, it is necessary to determine where these electrical appliances will be located in the kitchen furniture. After this step, the places of sockets are determined.

It is important to understand that you should not install a socket directly behind the oven or hob. In addition to the fact that you can make a mistake in the size of the depth (when the fork is connected to the outlet, the cabinet may not fit), the principle acting, for example, during warranty repair. Is disturbed. I had to de.Energize, only then dismantle.

Therefore, it is better to place sockets in the cabinets neighboring on the left/right:

The height of the installation of sockets should be at least 30 cm from the floor. There is another location:

In this case, there is no inconvenience of use (access is limited by the depth of kitchen furniture; if there are lower furniture facades, they need to be dismantled; the probability of “not to fit” in size and not safe. Too close the location of the sockets from the floor; The chance to be under voltage of 220V).

When repairing, there is often a desire to use the old electrical wiring. In the case of a hob, if the old cable, at least 34 mm 2 copper can be thought about using this cable. If the old aluminum cable of the same cross-section or copper of a lower section, it is definitely better to replace with VVG-NG-36.

In the case of an oven, we already considered that its consumption of current 16a. This implies that the cabinet is fully loaded with work. If the cabinet is recorded from one machine with other consumers (lighting, other electrical appliances) that also consume electricity, the network and the machine operate can be overloaded (for example, an electric kettle and oven, the cabinet consumes 16a, kettle 6.5a. Total current 22.5A, therefore, the machine for 16A will turn off both the kettle and the cabinet). It will be wiser, provide for the cabinet a separate fishing line for a trimmer laid by the VVG-NG-32 cable.5, with your automatic 16a.

There is a situation when the repair has already been completed and instead of the planned installation of an electric stove, a decision is made to use the oven and the hob. As we have already determined above, the most successful solution is a separate fishing line for a trimmer (group) for the cabinet and for the hob. Even after repair, it is often possible to draw a fishing line for a trimmer to the shield under kitchen furniture (with an installation of a separate machine).

But you need to be prepared for the situation with the electric kettle described above. In favor of this method, one can only note that the real power of electrical appliances can be slightly lower than the passport, the loading of the electric cabinet is not always maximum (but do not forget about the holidays) is the main principle. When the cabinet works, nothing more works or look for a combination: such a percentage of the cabinet power-you can turn it on.

connect, oven

The fact is that the sections of the supply wires and the surface are different. So the wire from the cabinet to the outlet should have a section 2.5mm 2. And for the surface of at least 4mm 2. The protection machine for the hob 25a, 32a (depending on the specific model) is designed for sections from 4mm 2. So in the event of a fault of the oven, the surface assault rifle simply does not work, and this is fraught with a fire (the case when all the insulation burns, the closure will nevertheless occur, and the machine will work. We will not consider).

Connection of the cable to the oven cabinet

If you connect the oven to the mains, then it is very important to comply with all the requirements that are specified in the device passport. Regarding the connection of the electric oven, it should be said that it is important to take into account the condition of the network, as well as make sure that there are no current voltage jumps. Since, otherwise, you risk saying goodbye to your device.

To the network 220 in

Ask the question which machine to put on the oven? Remember that it is important to observe the power ratio and the availability of the safety of the devices. Connection to the 220 V network should be made only if there is a three.Pin fork, as well as with grounding. It is also worth remembering that when connecting the oven to the network there should be three jumpers.

To the network 380 in

If there is no fork, but you want to connect the kitchen equipment to the network of 380 V, you do not need to connect it yourself. There are many qualified specialists who will help you connect the fork to the oven cabinet.

Solving a problem with protective grounding

Any electrical appliances with a metal case and controls must be connected according to a three.Wire scheme. However, only new buildings can boast of the presence of a protective conductor in the sockets, in most apartments the ground will have to be performed independently.

connect, oven

It is necessary to tighten the third wire into the apartment from the hiring panel body. Despite the fact that the functions of the zero and protective conductor are combined in it, a separate vein is still necessary to avoid random reconnecting, for example, when replacing an introductory machine.

Connection of the induction hob

Connection Consider by example induction hobs Electric Panel (Electrolux). Such a panel has great power, it is not included in a regular household outlet, but in a power, designed for a current of more than 16 A.

A power outlet for connecting an induction stove is selected according to its load. The total load of the induction plate can be on average 25-32 A, depending on the quantity and power of the firewood.

In this case, an individual fishing line for a trimmer of electrical wiring should be laid to power the induction stove in this case. The cable section depends on the load of the induction plate: for current 25 A, the copper cable with a section of 4 kV should be laid. Mm, for load 32 a. 6 kV. Mm.

For safe operation of the induction stove, the electrical wiring must have a working protective grounding. That is, for a single.Phase network to connect an induction stove, a three.Core cable must be summed up. Respectively, the acquired set of power outlet with a fork should also have a third grounding contact.

If it is not possible to purchase a power outlet of the required power, then as an alternative option, you can connect an induction hob to the terminal block installed in the mounting box. The terminal block should withstand the rated current of the induction stove connected to it.

As for the cable, through which the induction stove is connected, in this case it all depends on the configuration. If the supply cable is in the kit, then it is enough to connect it to the terminal block directly on the induction stove, and then to the purchased power fork or in the terminal block. Depending on the selected method of connecting the induction stove.

If the cable does not make the kit, then it must be purchased separately. When purchasing a cable, it is necessary to turn to its cross section. It must correspond to the connected load. It is necessary to purchase a flexible three.Core cable with a section of 4 or 6 kV. Mm for nominal currents 25 and 32 and, respectively.

In order to avoid errors, connecting the cable to the plate itself, as well as to the plug fork, it is recommended to perform according to the generally accepted color marking: brown or black-phase conductor, blue-zero conductor, yellow-green-protective grounding conductor.

    If the cable is already connected to the terminal block of the electric stove, then it is necessary to check the correctness of its connection. At the terminals of the induction stove, the following marking of the conclusions is usually indicated:

Two.Phase and three.Phase induction stove connection

Certain types of induction hobs may provide for two or three.Phase connection to the electric network. If a three.Phase entry is made in the house, then such an electric stove is connected, as the manufacturer recommends. To two or three phases of the wiring of four or five.Core cables.

A three.Core cable is connected to a single.Phase household electric network, and special jumpers are installed in the terminal block on the induction stove, which usually come in the kit. If there is no jumper, then the connection to two or three phase terminals is carried out by the wire corresponding to the load of the electric stitch.

It should be borne in mind that if the kit includes a cable for a two- or three-phase connection, then it is not designed for single-phase inclusion, since when a single-phase connection of the induction stove, the load on the phase conductor increases to the total load of all phases.

Therefore, when using the four (five) phases on the stove for connecting to a single.Phase network, the cables are connected to the stove, and at the other end of the cable, when connected to the fork or in the terminal block, the phase conductors are shaken together and connected to one phase of the mains.

Either a new three.Core cable is purchased, which has a sufficient load ability for single.Phase connection of an electric stove.

Hobal panel Electric power kW

So, it is worth picking up a hob with such power that the cooking time is fast, but released by heat. Optimal.

The electrical device of the traditional design consumes the highest electrical power from all types in question, so we will start the review from this option.

    The most widespread market in our time were plates with four burners. Thus, the standard number of heating points over the decades of the existence of home plates has not changed. The connection is also similar. However, manufacturers went to modernize the heating sites, so they have different power:

Induction hob is the most modern type of equipment for heating food in the kitchen. Its average power is about 7 kW. However, keep in mind that this is the consolidated power of the device.

Due to the fact that cooking on the induction surface takes a minimum of time, the simultaneous work of all disks almost does not occur. And even if this happens, a short period of peak energy consumption is rapidly replaced by inaction, since the cooking has already ended. The soup was boiled, the fish was fried, the kettle boiled.

Thus, although the power of the induction plate is equated to the power of the usual electric stove, due to heating exclusively the bottom and lower part of the dishes (and not the air under it), electricity is consumed only for heat treatment of products. It is important to note that energy saving requires the use of special dishes in cooking.

Cable for electric stove

The correct choice of a cable for an electric stove is primarily important for electrical safety. The choice of cable for the slab depends on the power of the stove itself, as well as on the type of network (single.Phase, three.Phase).

In a single.Phase network, a separate cable with copper veins is connected to the plate from the circuit breaker to the plate. The cable section for the electric stove is selected based on the rated current of the machine (table. 1), which in turn is selected based on the calculated load.
