- 1). Choose the locations where you are installing the outlets. Follow local building codes regarding spacing and height requirements.
- 2). Install the electrical boxes for the outlets. If the garage wall is unfinished, install new-work electrical boxes onto the studs. If the wall is finished, locate the studs with a stud finder and then cut a hole in the drywall next to the studs with a drywall saw. Use an old-work electrical box for a finished wall.
- 3). Run an electrical cable from your home's main cable box to the outlets.
- 4). Punch out the knockout holes on the outlet boxes and slide the cable through them.
- 5). Remove about an inch of the sheathing around the cable with a wire stripper or utility knife and then remove about 1/2-inch of insulation from the individual wires.
- 6). Connect the wires from the electrical cable to the screws on the outlet, following the manufacturer's instructions.
- 7). Wrap electrical tape around the terminals on the sides of the outlet.
- 8). Slide the outlet into the box and screw it to the box.
- 9). Screw the plate cover onto the outlet.
