1. Location

You should choose to lay electrical wires in areas with minimal or distant explosion risks.

2. Laying method

It is divided into two methods: explosion-proof steel pipe wiring and cable wiring

Some knowledge about LED explosion-proof lights

3. Isolation and sealing

Use non combustible materials to tightly block the circuit passage, and protect the explosion hazardous environment between pipes and steel pipes passing through partitions or floors to varying degrees

4. Select wires

Explosion hazard, hazard level 1, area, copper wire or distribution cable; Huajing vibrates violently, using multi-strand copper core wires or multi-strand copper core cables; Underground coal mines, using aluminum core wires or cables

5. Allowable current carrying capacity

It should not be less than 1.25 times the rated current of the fuse and the set current for long-term delayed overcurrent release of the circuit breaker

6. Connecting the circuit
