Explosion Proof
Electrical equipment is defined and certified as explosion-proof when it is enclosed in a case which is capable of withstanding the explosion within it of a hydrocarbon gas/air mixture or other specified flammable gas mixture.

The equipment must operate at such an external temperature that a surrounding flammable atmosphere will not be ignited. Also referred to as ‘Flame-proof’ … [Read more...]
