Standard Answer for Correct Wiring of Electriclal Distribution Box for Home

The installation of household circuits is a crucial link, and the installation of electrical distribution box for home involves the safety of household electricity. The regular connection method of electrical distribution box for home is very practical and helpful for electricians.

1. The regular connection method of electrical distribution box for home:

The marking of the line terminal is that the zero line is generally used in an electrical distribution box for home consisting of a main switch and several branch line switches. The general main switch is equipped with a leakage protection function. When wiring, the fire line is multi-red. The color line is blue, black, or yellow. If it is a single switch distribution switch, the fire wire must be connected.

If you install an electrical distribution box for home, you need to purchase a household line, choose a four-square meter of about the same, and connect it through the fire line of the leakage switch to connect to the household main switch circuit breaker, and then connect to each room through the fire line. Since the zero line is public, it can be separated into each room. Before installing the electrical distribution box for home, you must purchase all the equipment involved, then measure the rated current and working voltage of the household circuit, configure a similar distribution box according to the household circuit, and then design a household distribution box wiring diagram. Through the wiring chart of the electrical distribution box for home, the construction and installation are very convenient. The wiring methods are different for different applications of distribution boxes, and the wiring diagrams for electrical distribution box for home are relatively simple. The wiring diagrams for electrical distribution box for home in places such as buildings or power plants are more professional.

2. The precautions for installing electrical distribution box for home:

(1) Electrical distribution box for home is divided into metal casing and plastic casing, visible and invisible types, and their boxes must be intact.

(2) The internal wiring busbars of the household distribution box should set up zero line, protective grounding wire, and phase line separately, and must be intact and well insulated.

(3) The installation bracket of the air switch should be smooth and unobstructed, have sufficient space, be installed in a dry and ventilated place, and be easy to use. The distribution box must not be installed inside the box to prevent fire.

(4) Electrical distribution box for home should not be installed too high, and the installation height is generally 1.8 meters for easy operation; the electric pipes entering the distribution box must be fixed with lock nuts.

(5) If the household distribution box needs to be perforated, the edge of the hole must be smooth and clean. When the distribution box is embedded in the wall, it should be vertical and horizontal, leaving a gap of 5-6 millimeters on the edge. The wiring inside the distribution box should be regular and neat, and the terminal screws must be tightened.

(6) Each circuit must have sufficient length and no joints. After installation, the name of each circuit must be marked, and the residual materials in the distribution box must be cleaned up after the installation of electrical distribution box for home.
