What's Wrong Here?

Hint: Is this a permitted wiring method in a motor fuel dispensing facility?


How well do you know the Code? Think you can spot violations the original installer either ignored or couldn't identify? Here's your chance to moonlight as an electrical inspector and second-guess someone else's work from the safety of your living room or office. Joe Tedesco, who has a knack for finding shoddy electrical work, did the dirty work and found this mess. Now it's your turn to identify the violation.

Find the Answer



I discovered this violation after filling up my vehicle at a gas station in Cambridge, Mass. As noted in 514.4 of the 2005 NEC, “All electrical equipment and wiring installed in Class I locations as classified in 514.3 shall comply with the applicable provisions of Article 501.” The approved wiring methods for a Class I, Division 1 location are noted in section 501.10. Another reference worth noting is 514.7, which sets forth the requirements for wiring and equipment located above Class I locations.
