Sockets and switches must be installed during the decoration, but how high these components should be from the ground and how to install the safest, but not everyone knows. Experts pointed out that the following three points should be paid attention to when installing switches and sockets:
Install switches and sockets to ensure safety at three points
First, master the height. When installing the socket, the surface-mounted socket is not less than 1.8 meters from the ground; the concealed socket is not less than 0.3 meters from the ground. To prevent children from getting an electric shock, touching with your fingers, or inserting a metal object into the power hole, you must use a safety cover. Safety socket.
Secondly, clear the zero line of fire. The construction wiring requirements of the single-phase two-eye socket are: when the holes are arranged horizontally, it is left zero and right fire, and when they are arranged vertically, it is up and down zero; when the single-phase three-eye socket is installed, the uppermost ground hole must be firmly connected to the ground wire 3. Make sure that the connection is correct and must not be connected. The remaining two holes are wired according to the rule of left zero and right fire. The zero line and the protective grounding wire must not be misconnected or connected as one.
Third, separate lines for high-power appliances. The refrigerator should use an independent three-eye socket with protective grounding. It is strictly forbidden to connect the self-made grounding wire to the gas pipeline to avoid serious fire accidents. The socket of the range hood should also use a three-eye socket, and the protection of the grounding hole must not be taken lightly. The bathroom is easy to get wet, and it is not suitable to install ordinary sockets. Waterproof switches should be used to ensure personal safety.
