When 120-volt receptacles and TV outlets are mounted in double-gang boxes, ____ is required in the box to isolate the TV conductors from the power wiring.

Question

Quizplus · Accepted Answer

A barrier is required in the box to isolate the TV conductors from the power wiring. This is because the power wiring can generate electromagnetic interference (EMI) that can interfere with the TV signal, so it is important to keep them separate. A metal EMI shield, double-grounding, and double-insulation are not necessary for this application.
