COURSE PURPOSE
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. This class will focus mainly on the first few articles in Chapter 5 of the NEC and discuss the different classes, divisions and zones and what they mean for electrical installers.
