Electrical equipment installation is a compulsory course for every decoration worker. An excellent electrician should not only connect the wires beautifully, but also conform to the electrical specifications, so as to ensure the safety of electricity use.

For example, once the wires are decorated, workers put the live wire and the zero wire upside down, because the colors of the wires are not necessarily standard, and sometimes some electricians don't specifically distinguish colors during construction, so it is difficult to find that such wires can be electrified, but there are certain security risks. Because some electrical appliances have their own switches, the switches on them control the front line. Turn off the switch on the electrical appliance and often disconnect the front line, so as to achieve the effect of power failure. If you accidentally connect it backwards, the switch on the electrical appliance will close the neutral line, so even if it is in a power-off state, it does not constitute a loop power-on, but the interior of the electrical appliance is still in a charged state, and we are usually prone to get an electric shock or burn the internal circuit of the electrical appliance, causing risks such as fire.

Then how to connect the wiring of the household distribution box is beautiful, and it is a formal connection.

The laying of home circuit is a crucial link, in which the installation of home distribution box involves the safety of home electricity. The conventional connection of household distribution box is very practical and helpful to electricians.

The wiring method is shown in the above figure. The symbol of live wire at the incoming terminal is L, and the symbol of neutral wire is N. The general household distribution box consists of a main switch and several pink wire switches. Generally speaking, the main switch has the function of leakage protection. When wiring, the live wire is wired with red wire, and the zero line is blue, black or yellow. If it is a single switch distribution switch, the live wire must be connected.

If you install a household distribution box, you need to buy a household cable, and you can choose a four-square-meter one. It is connected to the home main switch through the live wire in the leakage switch, and then connected to the switch in each room through the live wire. Because the zero line is common, it is enough to divide it into each room.

How to connect the distribution box beautifully? The normal connection of household distribution box gives you the standard answer.

1, it is forbidden to use electricity or gas welding to open holes or reams on the distribution box, to open long holes and to open holes at the back. Usually, there is no opening on the side of the junction box, and the opening of the junction box should be suitable for the pipe diameter.

2. The wiring in the box (panel) should be neat, the loop number should be complete, the identification should be correct, the wires in the box should be horizontal and vertical, and there should be no splicing phenomenon. The wires should be closely connected, and the core wire should not be damaged or broken. The cross-sectional area of the wires pressed on both sides of the screw under the washer is the same, and the wires are closely connected, so that the core wire will not be damaged and the strands will not be broken. The cross-sectional area of the wires crimped on both sides of the screw under the washer is the same, and no more than two wires are connected on the same terminal, and check washer and other parts are complete.

3, indoor lighting distribution box installation straight, the wiring in the box is neat, no splicing phenomenon.

4, wire connection is close, not to hurt the core, not twisted wire, electricity circuit logo is clear.

5. The wiring in the distribution box is basically neat, the conductor color is selected correctly, the loop number is complete and correct, and the door of the box is grounded reliably.

How to connect the distribution box beautifully? The normal connection of household distribution box gives you the standard answer.

1, household distribution box is divided into metal shell and plastic shell, which are surface-mounted and concealed, and its box body must be intact.

2. The wiring bus in the household distribution box should be equipped with zero line, protective grounding line and phase line, which should be intact and well insulated.

3. The mounting bracket of the air switch should be flat and have enough space, and should be installed in a dry and ventilated place without obstacles and easy to use. Do not install the distribution box in the box to prevent fire.

4. The distribution box of household distribution box should not be installed too high, and the general installation elevation is 1.8m, which is convenient for operation; Electrical pipes entering the distribution box must be fixed with lock nuts.

5. If the distribution box of household distribution box needs to be punched, the edge of the hole should be smooth and bright. When the distribution box is buried in the wall, it should be vertical and horizontal, with a gap of 5~6 mm at the edge. Wiring in the distribution box should be neat and orderly, and the terminal screws must be tightened.

6, each loop into the line must have enough length, can not have a joint, after installation, indicate the use name of each loop, household distribution box after the installation must clean up the residue in the distribution box.
