How to connect the explosion-proof lighting switch? Xiao Bian summed up the precautions for the explosion-proof lighting switch wiring, I hope to help everyone:
1 The switch installed in the same building and structure should adopt the same series of products. The on/off position of the switch should be consistent, and the operation is flexible and the contact is reliable.
2 The position of the switch should be easy to operate. The distance between the edge of the switch and the frame should be 150~200mm; the distance of the switch should be 1.2~1.4m, the distance of the switch should be 2.2~2.8m, and the outlet of the cable should be vertical. Underneath, the cable is not easy to break.
3 The switch of the same model installed side by side shall be at the same height from the ground, and the height difference shall not be greater than 1mm; the height difference of the switch installed in the same room shall not exceed 5mm; the adjacent spacing of the side-mounted cable switch shall not be less than 20mm.
4 The single-pole switch should be strung in the phase line circuit, not in the neutral line circuit, which is beneficial for the safety of repairing or cleaning the lamp.
5 The switch should be installed firmly and must not be fixed with only one screw.
6 In the dusty and humid rooms such as kitchens and bathrooms, try not to install the switch. When installing, use a moisture-proof and waterproof switch. Outdoor switch, apply waterproof switch.
7 The mounted switch shall be installed on a wooden platform with a thickness of 15mm; the concealed switch shall be installed in combination with the panel, junction box and adjustment plate (if any). The panel installation shall be straight and tight and flush with the wall. .
8 switch incoming and outgoing lines should use the same color of wire.
9 wire ends should be pressed into the terminal block, there should be no exposed wires on the outside.
10 The wiring inside the switch box should have a certain margin.
