Why does running a power cord behind the wall for a wall-mounted TV violate the electrical code?
Saturday, July 20, 2019
The National Electrical Code (NEC) does not allow a power supply cord to be concealed in the wall, per NEC 400.12(5), which states that power cords shall not be used “where concealed by walls, floors, or ceilings or located above suspended or dropped ceilings.” So running the cord through a face plate, like in the photo above, makes the installation look neat and professional, but it is not code compliant.
Luckily, there are installation kits, like the PowerBridge® shown below, that use NM-cable and a listed connector between the inlet and outlet boxes to make the installation code-approved. The only exception would be if you live in an area that does not allow NM-type cable, such as New York City or Cook County, Illinois.
