mistake

Supervisor reminds: Before wiring, the number of household appliances and the port specifications of wires should be considered according to the total number of household appliances and the subsequent increase of household appliances. High-power appliances such as refrigerators, air conditioners and microwave ovens need to use separate circuits. When wiring, we should not only consider the current capacity, but also consider the future electricity consumption. Separate wiring of high-power electrical appliances is beneficial to line inspection and maintenance.

Second, the strong electricity between the kitchen and bathroom is on the wall

correct

mistake

Supervision reminds: Toilets and kitchens are damp places. Once the ground seeps, strong wires will cause safety hazards. Moreover, because these two places will be strictly waterproof, slotting in the ground will affect the waterproof performance of the whole room.

Third, the lines are vertical and horizontal.

correct

mistake

Supervision reminds: many construction workers try to save trouble by pulling diagonal lines when wiring, which seems to save trouble and money, but it leaves hidden dangers for future maintenance. Horizontal and vertical standard wiring can let the owner know the location of the line when punching holes in the future, so as not to punch through the pipeline, and diagonal lines are inevitable.

Fourth, the wires should be insulated.

correct

mistake

The supervisor reminds: the line cannot be directly buried in the plastering layer, the wire should be insulated, and the wire in the sleeve should not be twisted or jointed. It is convenient to check and maintain the cable in the future, so as not to open the wall and take the wire.

Five, the conductor section in the casing should be standard.

correct

mistake

Supervisor reminds: The wire will generate a lot of heat when it is used. If there is not enough space in the casing and there is not enough heat dissipation space, it will lead to safety hazards. Generally speaking, the cross-section of the conductor in the casing cannot exceed 40% of the diameter of the casing.

Six, strong wires and weak wires should be separated.

correct

mistake

Supervisor reminds: the current and power of strong and weak current are different, and they are connected in the same box, which will affect the use of weak current (cable TV, telephone, network), such as telephone noise, network instability and so on. Pay attention to this detail when wiring, so as not to affect future use.
