Content: How to Cut Out Drywall for Electrical Boxes
It’s important to lay out the location of electrical boxes and rough plumbing carefully. Draw the cut on the drywall about 1/8-inch larger in all dimensions than the outside of the box. You can skip this step, but for the cleanest cut, score the drywall with a knife. Then, push the jab saw through from the front of the board and cut along the layout lines. It’s harder than you might think to accurately lay out for cutting electrical boxes. For speed and accuracy, pros make these cuts with a drywall router instead. Drywall routers are small handheld routers that use 1/8-inch-diameter self-guided bits. The center of the box is marked on the board, and the rough wiring is pushed well back into the box (be sure the circuits are turned off). Then the board is screwed in place with just a few perimeter screws. With the bit set about ½-inch deeper than that drywall thickness, the router is turned on and plunged into the center of the box.
