Precautions for installation of underwater lights

1. For the selection of led underwater light, attention should be paid to the waterproofness, power supply voltage and power consumption of a single lamp.

2. Calculate the cable diameter: Generally, underwater lights use low-voltage safety voltage, involving low-voltage and high-current. The power supply affects the voltage drop across the line. The voltage drop at the end of each line must be calculated first and redundancy reserved.

3. The isolation transformer and leakage switch of the power supply of the underwater light must be arranged outside the 2 zone to avoid electric shock accidents.

4. Whether it is surface mounted (stand-mounted underwater light) or mounted (embedded underwater light), a cable of 0.6-1 m long should be reserved, avoid the need to drain the water in the pool when the led underwater light is broken. In this way, even if the light is broken, the light can be hoisted from the water to the surface, the wiring and wiring can be replaced, and waterproofing can be done. 

5. For other wiring, the wiring joints should be waterproofed.
