What's Wrong Here?

These two coupled raceways were located on a building's rooftop.


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

The following individuals correctly identified the Code violation shown in the February photo: Geoff Stephenson, electrical designer, Stearns and Wheler, LLC; Michael K. Lenihan, project engineer, Summit Systems Co.

Both winners noted that an improper fitting had been used to make a transition from electrical metallic tubing (EMT) to liquidtight flexible metal conduit (LTFMC) on the rooftop of this building. The jacket of the LTFMC appears to have been slipped over the threads of the fitting. This installation violates the requirements of 300.15, which notes that fittings and connectors shall be used only with the specific wiring methods for which they're designed and listed.
