Hazardous Locations Wiring
HLW102
COURSE DESCRIPTION
Hazardous locations can create devastating explosions when ignited, but these areas are widely misunderstood when it comes to wiring practices. Installing the wrong components, raceways, enclosures or devices in these areas, as well as using testing devices not rated for these areas, can have catastrophic consequences.
