Indoor wiring method

Before indoor wiring, we should fully understand the capacity of household appliances and consider the number of wires and the port specifications of wires. This paper will introduce the methods and precautions of indoor wiring.

Household appliance capacity

Before wiring, it is necessary to consider the number of wires and the port specifications of wires according to the total number of household appliances and subsequent household appliances. High-power appliances such as refrigerators, ovens and air conditioners need to use separate lines.

Strong electricity passes through the walls of the kitchen and bathroom.

Generally, kitchens and bathrooms should not be wired on the ground, but on the roof along the wall. Considering the strong functionality of the kitchen and bathroom, the requirements for floor waterproofing are very strict, and the floor slotting and wiring will affect the waterproof function of the whole room.

This line is horizontal and vertical.

The horizontal and vertical lines have now formed the construction standard of wiring, but there are also many early construction workers who stay in order to save trouble. Oblique laying seems to save trouble and money, but the wiring project is not convenient to maintain as a concealed project.

Wires should be insulated.

Buried lines should not be directly buried in plastering layer, but should be covered with insulating pipes. The wires in the sleeve shall not be twisted or jointed. Under normal circumstances, when a group of wires are buried, it is not allowed to exceed three turns. If there are more than three turns, you must take over the road box.

The total cross section of the wire should be standard.

The total cross-section of a group of wires composed of insulating sleeves should not exceed 40% of the sleeve diameter, that is to say, 60% of the movable space should be reserved.

Strong wires and weak wires should be separated.

Strong current and weak current cannot be distributed cross, and the same junction box cannot be used. The standard situation is that strong current and weak current should be connected in two different junction boxes, and the distance between them must be greater than150 mm.

Pay attention to the configuration circuit diagram

After the completion of the construction, in addition to the power-on inspection, the construction team will also provide detailed circuit configuration drawings to the residents.
