What's Wrong Here?

Aug 1, 2004 12:00 PM, By Joe Tedesco, NEC Columnist

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.

Hint: Is this a hallway luminaire or a receptacle in disguise?

Kristian M. Koellner, senior engineer, system protection, SRP, Phoenix, submitted this response to the photo in the August issue. “No unnecessary splices or taps are allowed within or on a luminaire (fixture) per 410.28(D), and wiring on or within fixtures must be neatly arranged and cannot be exposed to physical damage per 410.22. Also, excess wiring must be avoided. This wiring method is not listed to be used in this manner.”

Dan Naugle, P.E., engineering manager, Boeing, Moore, Okla., submitted this comment. “As is almost always a given with your examples, this installation violates 110.12 workmanship criteria. In addition, this particular installation appears to violate 334.15(A) and (B) and 334.30 regarding the installation of Type NM cable; 406.4 regarding receptacle mounting; and 410.22 regarding protection of wiring on or within fixtures.”

Todd Volkmeier, P.E., electrical engineer, Advantage Point Group, St. Paul, Minn., cited the following violations:

“410.28(D) — No unnecessary splices or taps can be made within or on a luminaire.”
“410.22 — The cable shown may not be rated for the high temperatures found in a light fixture.”
“406.4 — Receptacles must be mounted in boxes and securely fastened in place.”
“406.3.A — Receptacles shall be of the grounding type.”
