Pay attention to the following points when installing the socket:
(1) The installation height of the socket shall be installed according to the design requirements when the design is specified; when the design is not clear, the following requirements shall generally be met:
The socket with the safety door is not less than 0.3M.
The socket without the safety door is not low with 1.8M.
It is recommended to purchase sockets with safety gates as much as possible, as the prices are not much different.
(2) Sealed waterproof and splash-proof sockets should be used in the bathroom or other wet places.
Note: The socket with safety door is a plastic baffle (safety door) in front of the general metal socket with the metal reed of the jack. Three-hole socket, when the plug is inserted, the grounding pile head (slightly long) is inserted into the hole first, and the mechanism inside the socket opens the other two hole doors. The two-hole socket must be inserted into the socket pile head at the same time, and the safety door can be opened to prevent young children. Childhood mistakenly inserts metal objects to cause a safety accident.
(3) When the socket is installed, its panel should be straight and close to the wall. And the wiring (phase) should meet the following requirements:
Single-phase two-hole socket, facing the right or upper hole of the socket and connecting the phase line (fire line); the left or lower hole is connected to the zero line.
Single-phase three-hole socket, facing the right hole of the socket and connecting the phase line (L, fire line), the left hole is connected to the neutral line (N), the upper hole is the grounding line (PE)
