Whats Wrong Here?

How well do you know the Code? Can you spot violations the original installer either ignored or couldn't identify himself? Here's your chance to second-guess someone else's work from the safety of your living room or office. Our NEC meister Joe Tedesco has done the dirty work and found the violation. Now it's your turn to tell us what it is. Be one of the first three people to identify the violation

 

 

David Marcotte, senior electrical designer, Bergmann Associates, Rochester, N.Y., questions the circuit's equipment grounding conductor. “Make sure it stays in the box (250.148),” Marcotte wrote. “I would bet the electrician, or wannabe electrician, was doing this work around the holiday season and was in need of practice for his holiday wrapping. And how about the teledata box in the background? Looks mighty inaccessible to me. Good luck installing a plate on that box.”

Ben Mickler, owner, Benchmark Electric, Inc., Zebulon, N.C., added, “Be sure to check Section 314.20. A box located in a wall with a surface of noncombustible material must be flush or recessed no more than 0.25 inch.”

John Penn Jr., P.E., associate, Steinle Construction Engineers, Inc., Wilmington, Del., would verify compliance with 250.4(A)(3). “Make sure that the grounding conductor is not wrapped around a non-current-carrying conductive material connected to thermoplastic conduits,” he wrote. “This would create a non-effective ground-fault current path.”

Author's note: All winners also noted that the number of extension rings installed isn't a problem as long as the conductors in the box can be extended at least 3 inches outside the opening (300.14).
