I would like to remove 2 wall sconces from my living room. However, after I took the fixtures down, I didn't realize there would be 2 wire receptacles? that would need to be sealed up. How do I close up the 2 holes that are left after removing the fixtures? Thanks, I'm new at this stuff!
To follow the National Electric Code and to be safe, the fixture boxes cannot be plastered over. As long as live wires remain in the box it must remain accessible (even if they are switched off). This means that you may install an UL approved cover but you cannot seal it from access. If the unused wires are removed altogether, the holes may be patched over. However, this may be harder than it appears and may affect other outlets or lights elsewhere in the house. The wires and boxes could be relocated to the attic (which is generally considered by the NEC to be accessible) but may require someone with a good working knowledge of electrical systems. Hope this helps.
