National Electrical Code

Join NFPA Senior Electrical Engineer Mark Cloutier for a discussion of 501.10 Wiring Methods Protection Techniques. The presentation will address how both relate to how hazardous locations are protected from fire or explosion hazards due to flammable gases, flammable liquid-produced vapors, combustible liquid-produced vapors, and combustible dusts.
In the Lightning Round of the inaugural NEC Challenge Championship held on January 24, the remaining two contestants, Robert Watkins, Jr., and Derek Vigstol, competed in a lightning round quiz of National Electrical Code® questions in 60 seconds, with the intention of answering as many questions correctly as possible before time ran out. Robert went first and answered 5 out of 6 questions correctly before the timer buzzed. Derek answered 6 out of 7 questions (the buzzer sounded during the 8th question) correctly. In the end, Derek was declared the 2014 NEC Challenge Champion, with Robert taking 2nd place, and the third contestant, who competed in the earlier two rounds of the Championship, Joseph Brinley, took the 3rd place prize.
