How to connect the socket master switch?

1, the wiring of the wall socket should be powered off to ensure safety, and then read the standard letters behind the socket clearly, where L is the fire line to connect the red line, N is the zero line to connect the yellow line, and the rest of the holes should be grounded, so as to connect the green line or the blue line, and all of them can be fastened firmly before the socket panel can be installed.

2. The position of the switch socket is very important during installation, but it should be selected according to the function and usability of the electrical appliance, and it cannot be installed on the tile and waist line. When installing on the ceramic tile wall, it is necessary to punch holes, and its border should be controlled within 2mm larger than the bottom box, and it cannot be made into a round hole. The bottom box should be as flush as possible with the tiles. Do not install it on two or more tiles, otherwise it will easily damage the tiles. It is best to install it in the middle of the tiles.

3. The exposed socket is higher than 1.8m from the ground, and is usually used to use electrical appliances such as air conditioners. The height of the concealed socket from the ground is greater than 0.3m. Pay attention to prevent children from touching the power supply with their fingers or stabbing the power supply with metal objects, which may lead to electric shock. The horizontal distance from the door frame is 150-200mm. When choosing a socket, it is best to have a safety cover. Generally, the wiring construction of two-hole sockets should follow the principle of "left zero and right fire" in horizontal row and "zero fire" in vertical row.
