Driving the electricity connection

Sometimes it happens that you need to install an electric meter, and call a professional electrician is not possible.In compliance with safety regulations, the electricity connection can be performed independently.

Detailed information described in this article can be found below in video connection the electricity , andbelow - we analyze this process in more detail.

to perform the work necessary to prepare the tools - screwdrivers and indicator equipment - electric meter and circuit breakers.

When buying a meter should be paid to the technical characteristics of the device.They usually appear on the back side.The maximum current may not exceed the power settings, which are specified in the form of symbols (e.g., 5-15 or 10-40 A A).According to the approved standards for the apartment allocated to 16-25 amps, and equipped with electric - 40 - 63 Amps.Mains voltage may be - a three-phase (380 V) or a single-phase (220 V).

clear that the electricity connection in the apartment is made to account for the electricity consumed.The devices can be divided into mechanical and electronic, single and three phase.They are connected in a straight line pattern, which is easier to apply and dissemination.This connection does not require the installation and use of additional current transformers.

Wiring the electricity

Despite the fact that the counters produce different manufacturing plants, in all units the same arrangement of terminals to which the wires are brought.For convenience, the image of the electricity meter connection diagrams indicate on the back of the lid placing terminals.

What rules the electricity connection there?All modern devices and modular units are installed in protective boxes of self-extinguishing plastic.They may be built or external.To start, you need to build in box in the wall, since the electric meter will be installed in it.

First , on the rail in a protective box alternately set:

1. breaker, which performs the function of main switch and protects all wiring elements of a short circuit,
2. middle - place the electric meter,
3. second machineto output wires.

Second , on the electricity meter filling unscrew the screw, which is located in the lower part of the center cover and remove it.

Under the protective cover located on the contact screw terminals.They promote good interaction between the wires to the terminal.

screw clamps are arranged as follows:

1. bottom row (4 screws): connect the supply phase connection outgoing phase, to supply neutral wire, the waste zero cable,
2. top row of clamps for fastening terminals, power supply wirescoming out on the point in the apartment (light switches or sockets).

Third , you need to make sure that the electric voltage supplied to the apartment, there is no connection to the single-phase and three-phase electricity meter.

• By summing circuit breaker feeding the wire (zero - and right phase - left).Remove insulation and we clean, and connect to the machine through the upper contacts.
• For wiring with the circuit breaker on the counter using a certain section of the wire.section calculation is made taking into account the total capacity of all electrical equipment in the apartment.Use a hard or soft cord.
• With automatic feeding phase wire is connected to the lower left of the counter screw.To do this, insert the terminal into contact and fasten the clip.
• Then connect the neutral wire from the circuit breaker to the third counter contact.
• The exhaust from the machine cable is connected as follows: the second lower counter screws - to the waste machine;from the fourth clip - to exhaust single-pole switch.
• Check all the screws and pins.Wear protective cover on the electric meter and turn the screw to seal.

After connecting the meter with your hands, you must call the staff for checking and sealing devices.
