Hazardous Locations: Seals, Wiring & Equipment
5:25
Explosionproof equipment doesn't stop an explosion from happening — it just keeps that explosion from escaping.
In this lesson: the 3 hazard classes (gas, dust, fibers), Division 1 vs Division 2, what "explosionproof" actually means (containment, not prevention), conduit seals and the 18-inch rule, strict Division 1 wiring methods vs more flexible Division 2 methods, the Zone system alternative, intrinsically safe systems, Class I vs Class II equipment, and real-world examples.
Based on the 2023 NEC (Articles 500, 501, 504).
