How To Install Wall Switch Safely
Wall Switch is an indispensable electrical appliance in home decoration and is also the most frequently used electrical appliance. The installation of Wall Switch is also very particular. If it is not installed properly, it will be dangerous when used. There are generally four situations of improper installation: the first is that two wires are connected to a pile head; the second is that the zero and phase lines are connected incorrectly; the third is that the switch is installed on a flammable object, the wire core is exposed outside or water vapor penetrates, causing a short circuit, so the switches and sockets in the bathroom must be equipped with waterproof boxes; the fourth is that the working voltage and working current do not match the socket power, and it is overloaded for a long time. So what should be done when installing switches and sockets?
First, the switch should be 130~150cm from the ground and 15~20cm from the door frame. It cannot be installed behind the door. The Wall Switch position with wall panels is at least 0.2M above the top of the board, the height of the exposed socket from the ground is not less than 1.3m, and the installation socket is not less than 0.3m. The kitchen and bathroom are determined separately. Do not install it on the bedside or desktop, and the closing direction of all switches should be consistent.
Second, splash-proof sockets should be installed in bathrooms and balconies, or equipped with waterproof boxes. They cannot be installed above bathtubs, faucets, or stoves, and they cannot be installed 20cm around gas meters.

Third, household appliances must strictly use two-hole sockets. The power of the bathroom heater switch is relatively large, so more space needs to be reserved. Electrical appliances that are often plugged in and out can use sockets with switches.
Fourth, calculate the load. Sockets without fixed loads are calculated as 1000 watts. Ordinary sockets use 2.5 square millimeter copper core wires.
Fifth, connect the ground wire on the three-hole socket, the left is connected to the neutral wire, and the right is connected to the phase wire; the two-hole socket is connected to the neutral wire on the left and the phase wire on the right.
Sixth, it must be installed firmly and the joints are tightened.
Seventh, confirm that all wires are fully in contact with the wiring piles of the switch and socket back seat during installation. Eighth, the switch is usually opened and closed with the opposite hand, the right hand more than the left hand, and is usually on the left side of the door. The door switch should be fluorescent.
Finally, pay attention to protecting the panel of the switch socket during decoration to prevent contamination.
