Wacky Antenna Wiring

Jon Turpin, Turpin Electric, Inc., Cambridge City, Ind., was kind enough to share this photo with us. Here’s what he had to say: “Russ, I came across this ‘multi-tasked’ receptacle while looking over a home for sale by a local realtor. It appears the previous homeowner wanted his TV antenna cable very close to the 120V power source. I was amazed to find the receptacle live!” I’m amazed too, Jon. I’m not so sure this method of wiring was a suitable method as recognized by Sec. 110.8. Section 110.3(B) requires equipment to be installed and used in accordance with its listing or labeling instructions. Drilling out a receptacle so an antenna cable can be shoved through the hole certainly does not comply with any instructions included in the listing or labeling for this duplex receptacle. The damage done to this receptacle makes me question the safety and integrity of this installation. Section 110.12(B) prohibits damaged parts that adversely affect the safe operation or mechanical strength of the equipment. This installation needs a do-over!

Kooky Panelboard Location

This photo was sent in by Chuck Cole. He says, “I found this in a hunting cabin in New Jersey. It had open holes in the panel (guess they ran out of duct tape for the upper opening). No support on the MC cable within 12 in. (top). The toilet was within the clearance. The top breaker looked to be over 6 ft, 7 in. The best part is, I was standing in the shower when I took the photo.” There are lots of violations to cite here. The lack of clear working space violates Sec. 110.26(A). Circuit breakers are required to be readily accessible as specified in Sec. 240.24(A). That same Section of the Code generally does not permit the operating handle of a circuit breaker, when in its highest position, to be more than 6 ft, 7 in. above the floor. I’m not sure if this hunting cabin would qualify as a dwelling unit, but, if so, Sec. 240.24(E) would prohibit these overcurrent devices from being in the bathroom. The missing knockout seal is a violation of Sec. 110.12(A). Unused openings must be closed in a manner that provides protection substantially equivalent to the wall of the enclosure. Duct tape certainly would not suffice for this purpose. Improperly supported MC cables violate Sec. 330.30(B).
