What is an explosion-proof distribution box?

Just like an ordinary distribution box, except that some dangerous areas need explosion protection, so some adopt flameproof type, with ordinary circuit breakers and terminals installed inside, but an aluminum alloy shell is added outside. It is very thick, so it is sealed to prevent other substances such as hydrogen from escaping. Besides, it doesn't matter whether there is an explosion or not. If you fry in this box, it won't go bad.

The other is a compound type: flameproof+increased safety type. The components installed inside are all flameproof, not ordinary components, but treated. Then add a security enhancement box. Do it. Nothing to lose!
