A Hidden Secret
Brandon Killian, an electrician from Coconut Creek, Fla., shared this fantastic Code violation photo with us. He encountered this danger when he was called out to troubleshoot entranceway lighting that was not working outside a gated living community. While replacing a bad photocell, he noticed the new camera system was fed via a transformer that was plugged into a 2-wire extension zip cord tucked right into the 60A panel. He also noticed that the 240V/120V panel was only fed with 120V; however, the main lugs were jumped-out so all bus tabs were energized.
Cutting off the male end of the cord set and connecting it directly to a circuit breaker could be considered a violation of Sec. 400.12(1). Using flexible cord sets, or extension cords as they are commonly called, in place of fixed wiring is simply not permitted. Per Sec. 110.3(B), using an extension cord in this manner would also violate the instructions included in the listing or labeling of the product.
A closer look at the bottom left of the panel also reveals the PVC conduit installed for the camera wires is just shoved into the opening without the use of any conduit connectors. This would most likely be considered a violation of Sec. 352.48.
Troubles in Paradise
James Hickman, a master electrician and vice president for One Hour Electric, Inc., in Maryland Heights, Mo., shared this photo with us, which he took while visiting a restaurant on the island of Isla Mujeres in Mexico. He noted this was just one of the many violations he spotted while he was there. Although I’m not sure which electrical code is used in this jurisdiction, this installation certainly makes for a great conversation starter when it comes to discussing NEC violations.
To begin with, using electrical nonmetallic tubing (ENT) in this sun-filled outdoor location would violate Sec. 362.12(7), unless the ENT is specifically designed to be sunlight-resistant. Burying the ENT directly in the ground violates Sec. 362.12(4). The position of the ENT on the tree could also be considered a violation of Sec. 362.12(8) because it could easily get damaged.
The cover used for the receptacles is a violation of Sec. 406.9(B)(1), since it does not provide an enclosure that is weatherproof when an attachment plug cap is plugged into the receptacles. It’s barely weatherproof now because the cover is not designed to be mounted in this position. Installing a cover in a position other than what it is designed and listed for violates Sec. 110.3(B).
