‘Tell Them What They’ve Won...’
Using the 2008 NEC, correctly identify the Code violation(s) in this month’s photo — in 200 words or less — and you could win something to put in your toolbox. E-mail your response to firstname.lastname@example.org, and we’ll select three winners (excluding manufacturers and prior winners) at random from the correct submissions. Winners will receive a set of insulated hand tools from Ideal Industries, Inc., valued at more than $125.* The set includes 9.25-in. insulated side-cutting pliers, 10-in. insulated tongue-and-groove pliers, and a 0.25-in. 3 6-in. insulated screwdriver. (* Please allow six to eight weeks for delivery of tools.)
Our three winners this month include: Matt Healy, estimator, Nickle Electrical Companies, Newark, Del.; Jeff Pinter, electrical contractor, Pinter Electric, Florence, N.J.; and Christopher Fay, electrician, South Shore Hospital, Pembroke, Mass. All three individuals made note of several violations in the “intimate wiring contact” photo.
