It needs to be judged according to the actual situation.
If the plug is low, the height of the socket from the ground will be controlled at about 30 to 35 centimeters|
If it is a high insertion mode, the height of the socket from the ground will be controlled at about 40 to 45 cm. When designing a high insertion mode, it needs to be higher than the height of the sofa.
If it is designed that the height of sockets on both sides of the sofa is about 30 cm, it is suitable for inserting floor lamps, etc. A 30 cm high socket is reserved on the side of the wall for boiling water.
If it is reserved on both sides of the sofa background wall, the height of the non-side table is 110 cm, and the height of the side table is 80 cm.
What are the precautions for reserving the socket on the sofa background wall?
- Socket wire installation
The power wire must be copper wire cross section. If aluminum wire is also used, it is recommended to replace it, because aluminum wire is easily oxidized, and the accident rate of using aluminum wire is higher than that of copper wire. When wiring, the principle of “live line into switch, zero line into lamp cap” must be followed.
- Install protective device
In order to avoid short circuit caused by water splash or oil pollution, it is better to install anti-splash box or plastic baffle on the socket panel. For families with children, it is recommended to install safety sockets with safety shields to prevent children from touching them directly with their fingers.
- Socket installation height
The wall switch socket can be divided into open and concealed installation. The open installation shall not be less than 1.8m and the concealed installation shall not be less than 0.3m. If the air conditioner is installed on the sofa wall, the air conditioner socket shall be more than 2m.
- Only one circuit
There is only one circuit in the old house. If one circuit is short-circuited, the power consumption of the whole room will be paralyzed. It is recommended that two or three circuits be selected for the socket.
- Reserve more sockets
In addition to the routine needs, the sofa wall in the living room also needs to prepare several sockets in the open space for the various electrical appliances purchased in the next life.
- Multiple appliances share the same socket
Multiple electrical appliances sharing the same socket can easily lead to overload, thus causing accidents. It is better to use independent sockets for high-power electrical appliances. General living room sockets are set every 2. 5 square meters. It is better to install 4 sets of sockets in the bedroom and 1 2 square meters per group.
Precautions for socket installation
The power wire of the socket shall use copper wire cross section, and the principle of “live wire into the switch, zero wire into the lamp holder” shall be followed when wiring, and leakage protection device shall be installed on the socket.
The installation position of each socket shall be no less than 1.8 meters from the ground for open installation and no less than 0.3 meters from the ground for concealed installation. The socket for kitchen and toilet shall be more than 1.5 meters, and the socket for air conditioning shall be at least 2 meters.
High-power electrical appliances such as air conditioners, refrigerators, range hoods, etc. need to use independent sockets, and several more circuits should be set to prevent a short circuit from making the whole room unable to use electricity.
In some wet spaces, it is necessary to install a splash-proof box or plastic baffle on the socket panel to prevent short circuit caused by oil and water vapor intrusion.
The working voltage and current of the lamp holder are not consistent with the power of the socket used. If the lamp holder is overloaded for a long time, it will cause a fire once the temperature is too high.
