Contact your local building authority for complete information. NEC 210-7 Receptacle Outlets shall be of the grounding type, be effectively grounded, and have proper polarity.Ĭode Adoption Information: The codes shown are examples only and may not be current or accurate for your application or jurisdiction. “A TV’s electrical cord could short out in a wall or in front of a wall and cause a fire generally speaking a claim would be paid if there’s a fire involved,” she said.Introduction to Electrical Codes for Outlets and Receptacles Janet Ruiz, the group’s director of strategic communications, said that with the caveat that every insurance policy is different, in general a claim on fire damage will be paid up to the amount allowed in the policy. If you have a question, send it to with the subject line “Ask Wirecutter.”Ĭorrection: When we first published this piece, we said, “If the house has a fire and the insurance company finds that a power cord was improperly installed behind a wall, they could have a reason not to pay out on a claim.” I reached out to several insurance firms, who pointed me to the Insurance Information Institute, a nonprofit organization that provides information on the insurance industry as a whole. Questions have been lightly edited for clarity. Whether you’re a renter or homeowner, there are some electrical wiring red flags you can keep an eye out for-and a few key pitfalls to avoid. Here’s a video from PowerBridge on how you install it (with some ’80s graphics and music you might enjoy.)Ĭhris adds, “Make sure your cables are CL-rated for in-wall installation as well.”

“You don’t want to have shorts in your wall. We spoke to Christopher Coache, a senior electrical engineer at the National Fire Protection Association, who told us that regular power cords aren’t rated to go behind walls. A regular power cord behind a wall can overheat or get damaged where you can’t see it. It’s against code, and for good reason-it’s a fire hazard and against National Electrical Code. We don’t recommend that you put your Sonos or TV power cords behind your wall.
Also, how approachable is adding a new electric socket? Thanks! -JJīefore we talk drywall, we should talk electrical safety. I’m interested in drywall-specifically, how to hide cords inside drywall that come out near a plug (example: hiding cords from Sonos speakers or a TV).
