Please note that improper installation of the switch socket can easily cause fire or electric shock. There are generally four cases of improper installation:

The first is to connect two wires on one pile head;

The second is zero, the phase line is wrong;

The third type is that the switch is installed on the flammable object, the core is exposed outside or the water vapor penetrates, causing a short circuit, so the switch socket of the bathroom and the like must be equipped with a waterproof box;

The fourth is that the operating voltage and operating current do not match the outlet power and are overloaded for a long time.

So what should I do when installing the switch socket?

First, the switch should be 130~150cm away from the ground, 15~20cm away from the door frame, and can not be installed behind the door. The position of the wall switch with the wainscoting is at least 0.2M from the top of the board. The height of the wall-mounted socket is not less than 1.3m from the ground. The installation socket is not less than 0.3m, and the kitchen and bathroom are fixed. Do not install on the bed or on the table, all switches should be in the same direction.

Second, the bathroom and balcony should be equipped with splash-proof sockets or waterproof boxes. Bathtubs, faucets and cooktops cannot be installed above, and 20cm around the gas meter cannot be installed.

Third, the household appliances are rigorously used with two-hole sockets. The power of the Yuba switch is large, and it is necessary to leave more positions. The electrical appliances that are often plugged and unplugged can be used with switch sockets.

Fourth, calculate the load, the socket without fixed load is calculated by 1000 watts, and the ordinary socket is 2.5 mm square copper wire.

Fifth, the grounding wire on the three-hole socket, the left connected to the neutral line, the right connected to the phase line; the two-eye socket is connected to the left line and the right line.

Sixth, to be firmly installed, the joint is tightened.

Seventh, confirm that all the wires are in full contact with the switch and socket rear seat wiring pile head during installation. Eighth, the switch uses the opposite direction of the hand to open and close, the right hand is more than the left hand, generally on the left side of the door, the entrance switch should use fluorescent type.

Finally, pay attention to protect the panel of the switch socket when decorating to prevent fouling.
