Connecting electric stove with his hands

Electric stove - an excellent choice for the modern kitchen.With proper installation and use, the device will properly serve for many years.Of course, for connecting electric cookers can be a qualified master, but if you want you can do it all on their own and a good save!

Check out the basic requirements for the connection of modern electric stoves, existing schemes, as well as guidelines for the direct installation of the device and its grounding.

Requirements for wiring

important!Before any manipulation of the wires and electrical appliances, turn off the electricity to your home or apartment.

Current models of electric stoves are usually sold without cord attached.It has a reasonable explanation: Safety requires that the connection of these devices was carried out by means of high-quality terminal blocks, ie,on the so-calledbezrozetochnomu method.In this embodiment, the compounds can increase the length of the supply cord and the machine instead of the more powerful models are allowed to install a fuse.

For connection is necessary to use the cable cross-section of 4 mm2 if the length does not exceed 12 m. In the case of the use of a long wire, the minimum allowable value of the cross section increases up to 6 mm2.In this case the installation of a separate machine for concrete slabs have to be made.

Connection via outlet is also acceptable.It is only necessary that the instrument is designed for a current of 32 A. Electric stoves consume a lot of energy, so to include them in simple household outlet is prohibited.

Thus, by the electric stove connection requirements can be combined into a short but important list, which includes the following provisions:

• to connect the device using a three-wire copper cable cross-section of 4 mm2libo from6 mm2, depending on the length of the cord;
• in the electrical machine is installed separately to the plate;
• performed installation protective devices;
• grounded plate method available.On the possible grounding options will be discussed at the end of the manual.

Wiring diagrams Cooktop

Before proceeding with the installation, read the existing scheme of the device connection.

Single-phase connection

most common variant.The most common in the apartments of apartment buildings.

When connecting single-phase connection of the unit will be as follows (see. Figure).

Terminals 1-2-3 and 4-5 are connected webs of copper 6 mm2.If you bought a modern stove required jumpers will be present in the kit.

Phase conductor (can be gray, brown or black) is connected to terminal number 1, 2 or 3.

Zero vein (usually a blue color) is connected to the 4 th or 5 th terminal.grounding wire (he Scheme yellow-green) is connected to the terminal 6 minutes.

Bolts terminal should be tightened until it stops.If poor connection terminals may get burnt, causing a fire.

In the case of rosette phase power connection wire in the plug and the socket is connected to terminals L, neutral conductor goes to the terminal with marking N, earth wire is allowed to go to the appropriate terminal (marked by a pattern of grounding, the letters PE or the word earth).

Bipolar connection

rare, but still found a two-phase connection.For example, A may be present, and the phase C and phase B will not.

This connection terminals 1 and 2 need to connect the bridge and through the connect phase A. Phase C is spent on the third terminal.The further procedure is similar to the previous connection methods.

Three-phase connection

With three-phase power is most often encountered the owners of private houses.Feeding the wire in such a situation would consist of four or five conductors.The voltage between zero and phase will be 220, and directly between phases - 380 V.

Under such conditions, electric will be connected by the respective scheme.Phases A, B and C will be used for the respective terminals 1, 2 and 3.

Connection terminals 4, 5 and 6 is similar to a single-phase connection.

Connect electric stove

Connection procedure remains the same for networks with any number of phases.There are some nuances, which you will find below.Connection will perform through the outlet.

first step

Choose a location for the device.Electric is classified as a high-power electric receivers.To ensure reliable and safe operation, on the wall near the stove, we set a power socket with earthing contact.In this current nominal outlet should be 32-40 A. The outlet will be three, for two- and three-phase networks of contacts for a single-phase power supply - five.

second step

be installed in a separate circuit breaker panel.If the network is a two- or three-phase, three-way switch is set to 16 A. In the case of single-phase network install Plank machine.Denomination switch should be 25-32 A.

third step

Mount wire for connecting electric cookers.The two- and three-phase networks using cable 5h2,5 VVGng brand to connect in single-phase power cord use 3x4 the same brand.Pull the wire from the electrical outlet to plug in our electric stove.

fourth step

Connect the cable to the outlet according to one of the schemes listed above.Close the cover of the socket.We work very closely, observing the established standards.If the connection is made using a three-core cable, the brown wire (it can also be white) is connected to the phase connector installed power outlet, the blue wire (can be white with a blue stripe) allowed on the connector "zero" and the core yellow-green combinea ground connector.Wires five conductor cables are often painted in brown, white and red colors.The order of their connectivity, as well as features outlet connectors labeling was considered earlier in the description of the schemes.

fifth step

We connect the plug with a flexible wire appliance.In this case we are sure to pay attention to the features plug marking.Connecting element is similar to an electrical outlet.

sixth step

Connect a flexible wire to the plate.At this stage, a lot depends on the model of the installed device and the number of phases in the home electrical outlet.In general, manufacturers led circuit boards to connect them to the supplied instructions, or else on the back units.Follow the manufacturer's suggested guidelines.

ends of flexible wire recommended obludit before installation into the terminal clamps - so will ensure maximum reliability.

seventh step

share the feed cookers cable shield, and then we clean the ends of the wires.Connect the phase conductors of the supply cable clamps on the Way of the machine.Guillou «zero» connect to a common bus for all conductors zero.Not only it remained attached yellow-green living.In modern systems, such wires are connected to the ground rails.In older networks such as TN-C grounding bus no.What to do?Read more.

grounding Guide cookers

When working in networks of the old model even skilled professionals often knowingly commit a blunder by performing various electrical grounding to the working zero bus.This connection is fraught with adverse consequences: if the zero wire is interrupted, the phase will pass through the load directly to the appliance and the user an electric shock.

Often electrical permit and another blunder, confusing places wires and zero phase.When performing such a "ground" the result will be similar to the previous case - the owner of the plate current can strike at any time.But you can not give up too, from vanishing.There are several solutions to the problem.Check out the available methods and select suitable for your situation.

first option - find out whether the grounded shield apartments

To do this, go to the housing office or any other service organization.If a representative of the company says that the shield enclosure is securely grounded, we will only have to connect the yellow-green wire to the body through a bolt.

If the representative of the service organization gives a negative answer or else confused in his testimony, perform grounding method described above can not be - it will either be ineffective or lead to the user's current impact cookers.

second option - for residents of apartments on the first floor and the homeowners

owners of such real estate may try to create a separate ground loop.He did so:

• of the outer wall of the structure to the ground-Ground steel rods with a diameter of 16 mm and a length of 250 cm in the amount of three pieces;
• connected rods dug band steel 4 cm wide and 0.5 cm thick;
• from the electrical panel displays ground (yellow-green) wire, pre-terminated with a tip;
• from the ground up to the circuit ground wire extends wire-rod.Recommended diameter of a wire -. 0.8 cm at the end of the wire rod pre-welded steel plate with bolt hole.Ground cable with a screw rod fastened to the plate at a minimum height of 250 cm from the ground level;
• grounding cable connected to a single neutral bus in the panel.This same bus connects the ground wire from the installed boards.

third option - ifgrounded not get

Shield not grounded, and make the personal ground loop is not possible?Then simply drowns out the yellow-green wire and leave it to the board for better times.

Cooker pay attention to this situation.

First, set it so as to prevent the likelihood of simultaneous user contact with a stove and various conductive elements such as faucets, sinks, pipes, etc.metal products.

Second, near the electric stove should be laid unless a special dielectric coating, the least dense dry mat.

Third, in the usual automatic plate replacing the differential model with a nominal value of 30 mA operation.

Fourth, take special caution and vigilance in operation ungrounded electric stove.

Important!Grounding electric stove pipe on water supply, sewerage and heating systems is impossible.Although these elements according to the rules and must be firmly grounded, the resistance of the ground one usually does not control.The result can be a failure of the appliance, the user an electric shock and harm to property, and not only his, but also a neighbor.Also it is impossible to ground electrical appliances to other utilities such as elevator shafts, ventilation ducts, etc.

Successful work!
