Installing an Electrical Outlet for a Wall Mounted TV

By Dave Rongey - Summary:

How to Install an Electrical Outlet for a Wall Mounted TV – There are some great cut-in boxes that can be used in either the wall or the ceiling which will avoid having to open up the wall.

Methods for Installing Power for a Wall Mounted TV

 I have a wall mount TV that I want to install in a bedroom, close to the ceiling.

  • I want the electric outlet work to be as non-invasive as possible.
  • Is it OK to go through the attic and mount a box to a rafter such that the outlet will actually be in the ceiling instead of in the wall?
  • This way, I can run Romex to the box and properly secure it to the rafter.
  • If I put a renovation box in the wall and drill a hole through the top plate of the wall structure, I can’t get into the wall cavity to secure the Romex to a stud.
  • Unless I take out a section of wall board and re-plaster.

  • Absolutely Mark, I have done this several times. Basically you install an electrical outlet box in the ceiling location of the TV.
  • This can be done for both the power and the coax cable. Understand that there are some great cut-in electrical boxes that can be used in either the wall or the ceiling which will avoid having to open up the wall.
  • A cable from a power source will need to be installed from the attic area or brought up from an existing wall receptacle.
  • While your at it, consider installing speaker wiring for a bedroom surround sound experience.

    Hi Phil,
    When electrical wiring will be penetrating materials such as wall board or sheet rock then it should be protected with an approved conduit. Have you considered having a recessed wall box installed? There are wall boxes specifically made for this type of application where the outlet power is in one section and the TV signal cable or any low voltage cable is installed in another adjoining section. This box typically is installed behind the TV so the spare cables may be tucked into the box, or if the inside wall space allows, the extra low volt cables may be tucked into the wall cavity. The problem with having the outlet installed into the attic is that it is not easily accessed. I believe the recessed boxes are made by the Arlington company which has a full line of electrical boxes to help you with your ceiling mounted TV.

    I have a ceiling mount for a television and would like to have an outlet installed by an electrician in the attic for completely hidden cabling.

    I have read that it is acceptable in Maryland to install an outlet in the attic and should include arc-fault protection. Am I correct in this?

    If the above condition is true, are there special requirements for the power cord running to the television? For example, should it be housed in conduit?
