What should be paid attention to when laying wires indoors?
1. Comprehensively understand the capacity of household appliances
Before wiring, consider the amount of wires and the port specifications of wires according to the total number of home appliances and the subsequent addition of home appliances. High power appliances such as refrigerators, ovens and air conditioners need to use a separate circuit.
Household appliances need to be constantly added and updated, and the power will also be constantly strengthened. When wiring, not only the existing capacitance, but also the future power consumption should be taken into consideration, and the separate wiring of high-power appliances is beneficial to the future line inspection and maintenance.
2. Strong electricity walking on the wall in the kitchen and bathroom
Bathrooms and kitchens generally cannot be strongly wired on the ground, but should be wired along the wall on the roof. Considering the strong functionality of the kitchen and bathroom, the ground waterproof is very strict, and the ground slotting wiring will affect the waterproof function of the whole room.
The kitchen and bathroom itself are wet places. Once the ground seeps, strong wires will cause potential safety hazards. In addition, functional rooms such as toilets and kitchens will be made watertight with ceramic tiles. In this way, it will be troublesome to repair the electric wires in the future.
3. The route is horizontal and vertical
The horizontal and vertical wire routing has now formed the construction standard of wiring, but there are also many early construction workers trying to save time and pull the diagonal line. Diagonal laying seems to save time and money, but wiring works as concealed works are not convenient for maintenance.
Many owners like to add some murals in their homes, which requires drilling and nailing on the wall. The standard horizontal and vertical wiring will let the owners know the location of the drilling, but the cable wiring without rules is easy to chisel lines.
4. The wires shall be sleeved with insulating pipes
Concealed lines shall not be directly embedded in the plaster layer, but shall be covered with insulating pipes. The wires in the sleeve shall be free of twists and joints. Generally, a group of wires shall not be buried with more than three turnouts, and more than three turnouts shall be connected to the junction box.
In the home decoration, in order to avoid affecting the appearance and save time, a group of wires are laid around several times, which will not affect the use in a short time. However, if one of the wires has a problem in the future, a group of wires will not be able to use.
5. The total section of wire shall be standard
The total section of a group of wires composed of insulating sleeves shall not exceed 40% of the diameter of the sleeves, that is, 60% of the activity space shall be reserved.
The wire will generate a lot of heat when it is working. If the wire space in the sleeve is insufficient and overcrowded, the heat dissipation space of the wire will be reduced, the service life will be reduced, and it is not convenient for the repair and twitching of the wire.
6. Strong and weak wires shall be separated
Strong current and weak current cannot be cross distributed, and the same wiring box cannot be used. The standard condition is that the strong and weak current should be connected in two different junction boxes, and the distance between the two must be greater than 150 mm.
The current and power of strong current and weak current are different, and they are connected in the same box at the same time, which will affect the function of weak current. For example, some owners' telephone noise, network instability, etc. are all interfered by strong current, so this small detail should be noted.
7. Pay attention to the configuration circuit diagram
At present, many houses adopt concealed lines, so it is difficult for householders to check the construction quality. According to the regulations, after construction, in addition to power on inspection, the construction team should also provide a detailed circuit configuration diagram for the household owner.
The wiring project directly affects the safety index of life, and also has a great impact on the addition and subsequent decoration of household appliances in the future. It is necessary to keep a detailed circuit configuration diagram for future renovation and line maintenance.
That's it Wiring All precautions for indoor installation.
