What should be electrical wiring in the kitchen?

Preparatory work for the

The first step is to prepare for the installation process and perform the following:

1. Check the existing wiringafter repair in a new building or with a complete replacement of electrical wiring in the house, this item is missing).
2. Independently calculate the power of all kitchen appliances.
3. Select the appropriate elements of the new electrical network: wires and cables, sockets, switches.
4. Create a standard scheme by its own conditions.

Let's briefly review each of the stages, so you know what the right electrical wiring in the kitchen should be.

Checking the old electrical network

At this stage you should determine which network you have in your apartment( or house) - single-phase or three-phase. In addition, you need to make sure that the wiring has a ground loop( three-wire wire), becausewithout "land" to exploit modern household appliances is prohibited. In new homes, as a rule, grounding is already present. Well, the last thing you need to do is determine the cross-section of the cable to know what loads your home network is designed for.

As for the last moment, here it is necessary to run ahead and note that for today the load on the kitchen wiring can reach 10 kW, therefore the cross-section of copper wires going from the junction box to the devices must be at least 2,5 mm.kv., betterif 4.

Estimated part of

After you figure out the old electrical wiring in the kitchen, you will need to calculate the total current load from household appliances yourself. Here everything is simple and the calculation is as follows: you need to write out the power of each electrical appliance and summarize all the values. In modern kitchens, the total capacity of household appliances can reach 10 kW, which is a great indicator for a single-phase 220-volt network. Based on this value, you will then need to select the correct cable cross-section and the rated current load of the outlets.

Selection of

components The first thing to do is to correctly select the cable cross-section, which will be removed from the apartment switchboard to the distribution box in the kitchen. For powerful home appliances, it is recommended to separate the individual cable from the panel( for example, to connect the oven).In the design work, we recommend using this table:

When the selection of the wiring section is finished, you need to determine the outlets and switches. They must be calculated, not less than 16 A for conventional electrical appliances and 32 A for powerful equipment. Make sure that the sockets are grounded. It is recommended to install a separate outlet on each electrical appliance, and fix a block of 2-3 pieces above the countertop, or a double model for connecting not very powerful equipment: multivarkers, kettles, etc., as shown in the photo:

As for the switches,are not presented. The only advice - when choosing switches, use those that have the least number of relief patterns. Ideally, the outlets and switches should have a flat casing that is easier to wipe off grease and dirt. In order not to disturb the interior of the kitchen, it can make a hidden electrical wiring by installing designer switches and sockets, the color "under the tree" or something like the option provided in the photo below.

Creating a scheme

Well, the last thing you need to do during the preparatory work phase is to draw a wiring diagram in the kitchen. To do this, we recommend that you take into account the advice that we have already talked about and which we will talk about further. Typical scheme of kitchen wiring looks like this:

After you have prepared all the necessary materials, you can proceed to the installation of electrical wiring in the kitchen with your own hands. About how to properly divide the line, now we will tell.

The basic process of

We will provide the installation instructions in steps to make it easier for readers of Electrics himself to perceive the material:

1. According to the scheme it is necessary to make the marking of the walls in the kitchen in-house. To do this, we recommend to make a homemade laser level, which will allow a horizontal and horizontal marking for the strobes quickly and with a minimum error.
2. By marking it is necessary to carry out the shrouding of the walls under the wiring, then lay the cable in ready-made fences and plaster the entire network of grooves in the wall.
3. In the prepared seats, you need to connect light switches, sockets and junction boxes.
4. The shield is equipped with a protective automatics for kitchen appliances and electrical wiring.
5. The finished electrical wiring in the kitchen is checked by the inclusion of electricity. If nothing sparks, does not make a noise and does not smoke, and at the same time all the equipment functions normally - you did it right!

That's all the instructions for installing electrical wiring in the kitchen with your own hands. As you can see, there is nothing particularly complicated, but there are still many incomprehensible moments, like what kind of automation should be installed, where it is best to conduct a cable, etc. This is what we are just now talking about, providing useful advice on wiring in the panel house and apartment!

Useful advices for

To properly wiring in the kitchen, we recommend that you take into account the following recommendations:

• The switch should be installed at the entrance to the room, at a distance of 20-30 cm from the doorway, at the height of the lowered hand so that it is possible to easily control the lighting even for the child.
• The height of the installation of the sockets in the kitchen must be different. One block of "electrical points" should be above the countertop, the second above, for easy connection of the hood. For a refrigerator, washing machine and dishwasher, the height can be 20 cm from the floor, but not less. The convenient location of all the outlets we provided on the diagram above, on it and orient yourself.
• For a powerful technique, you need to select an RCD with a rating of at least 40 A( leakage current 30 mA) and an automaton of 32 A. The remaining sockets will be enough to connect a 25-ampere circuit-breaker yourself.
• It is not recommended to conduct wiring in the open kitchen for safety reasons( near a sink, stove, etc.).In addition, the cable channels will be negatively reflected in the interior of the room. If you have a false ceiling, the cable must be stretched in the corrugation behind the drywall sheets.
• If you live in a hruschevka, where there is no ground, it is necessary to get out of the situation by installing a zeroing, but in this case, be sure to make sure that the neutral wire does not burn out in your switchboard.
• Do not install the sockets above or under the sink. Try to get them out, even under an apron.
• Bypass the device connection via an extension cord."Carrying" is an unreliable electrical point, which at high loads can melt and cause a short circuit.

On this instruction on how to make electrical wiring in the kitchen with your own hands, ends. Consider all the provided nuances and recommendations to ensure that the wiring is safe, convenient and durable!
