Knowledge of
power cables in the home
Power cable laying generally refers to the process of laying and installing
power cables along the measured route to form a power system. Reasonable wiring method is of great significance to ensure the transmission quality, reliability, construction and maintenance of the line. However, the laying position of power cables during decoration is not only the ceiling or the ground, but the specific method depends on the actual situation of the electrical appliances to be connected.
1. Wiring of household sockets
This method of wiring household sockets from the ground mainly uses common electrical equipment such as computers, networks and five-hole sockets. When installing electrical wiring in your home, it is necessary to ensure that the
power cables are intact to avoid safety hazards. Laying from the ground can effectively save the waste of materials, ensure the concealment and integrity of the socket circuit to the greatest extent, and reduce the occurrence of danger.
2. Lighting system and central air conditioning wiring
The wiring of household lamps, central air conditioners and other electrical appliances should be installed on the ceiling, and the wiring ducts should be carried out according to the measured lines. Once the
power cables are laid out, the power cables will feed the home electrical system through the pipes. By adopting this method, a large amount of materials can be saved, and it is convenient to arrange the lines individually, thereby effectively improving the safety of the lines. Therefore, when installing the lighting system and central air conditioning, the ceiling wiring is the most reasonable.
3. Toilet
The bathroom wiring is not recommended to go underground. Because the toilet is in a wet state all the year round, the probability of water seepage and leakage is greater than other places. If power cables age over time, there is an increased risk of electric shock and leakage. Therefore, when laying
power cables, in order to avoid damage to the
power cables, it is best to set hidden grooves on the wall or ceiling for laying. When laying, wrap the line with PVC pipe to prevent corrosion and wear.
Fourth, the seven principles of laying
(1) In order to avoid the interference of TV and telephone, the wiring strength power cable should not be in the same pipe, and the distance should be at least 30cm;
(2) Use the entire pipeline as far as possible for long-distance pipelines. If it is unavoidable to connect, it is necessary to use connectors, and the connectors and pipes should be directly bonded.
(3) If the cable tube is on the ground, it should be protected immediately to prevent extrusion and damage to the line, which will affect the later maintenance;
(4) When the wiring length exceeds 15m or more than 3 elbows, a junction box should be installed in the middle to avoid the pipeline being too long or bending multiple wires to pass through the pipeline
power cable during disassembly;
(5) Under normal circumstances, the installation of the air conditioner socket should be more than 2m above the ground, and the socket installation should be 30cm above the ground
(6) The connection between
power cables needs to be connected in parallel. The crimping method must be firm and the connection must be wrapped with insulating tape.
(7) Circuits for different purposes in the family, such as lighting, sockets, air conditioners, water heaters, etc. ·Should be wired in groups, so as not to affect the normal use of other electrical appliances during power outage maintenance.
