Also called an old-work box, these are electrical boxes with built-in clamps to fasten them into finished walls. All that is needed to install one is to cut a hole the proper size in the hollow part of a wall and insert the box. These can be used in drywall, plaster or paneling. They are best suited for adding wall receptacles and switches. Because they don’t offer much support, old work boxes are not a good choice for installing a new ceiling fixture.
Press a small board against the bottom of the outlet box to hold it flush with the ceiling while attaching the support assembly to the joists. Working through the channel, drive deck screws or nails through the holes in the metal hangers and into the joist. Use four screws on both ends of the support, two on each side of the hangers.
Hold a piece of plywood against the wallboard at each stud and press the crowbar against it to pry the molding off. If you have two-piece baseboards, remove one piece at a time starting with the base cap and then remove the wider parts.
After deciding the route, mark and cut the holes for a new receptacle, switch or fixture using the outlet box as a template. Before installing the new box, use the hole to aid in running the new cable.
If you want to use a source with the maximum wires already present, it may be possible to split the source before it enters the box. Cut access to the wiring through the wall material and add a junction box to splice the new outlet into the circuit. Cover the box with a blank plate to protect the splice.
A safety device designed to instantly break the electrical path if changes in electrical current flow are detected. GFCI receptacles are required in bathrooms, kitchens, garages and unfinished basements, as well as any exterior installation. GFCI circuit breakers are also available for protecting an entire branch circuit.
A circuit breaker or fuse box. Electricity enters the household circuitry through the service panel and is distributed from there through circuit breakers or fuses to branch circuits.
Use a straight edge held flat against the top of the base cap to keep your line straight as you pull the knife through the caulk several times until it’s cut cleanly.
