I Want To Change A 2 Outlet To A 4 Outlet In My Garage.?
If surface mounted, replace single box with larger box that can receive a cover plate that holds two duplex outlets.
If flush mount, you can replace the single box with a double box same as surface mount or you can consider just locating a new single outlet near the existing one, and extending the wire from the first to the second using same wire size as existing). Boxes are available with ears that lock the box to the drywall so that you don't have to mount the box on a stud.
TURN OFF POWER FIRST.
