Plugs are generally very similar; it is the fuse rating inside the plug that determines what amperes it can take. However, the wires connected to a 30-amp plug are different to those wired to a 20-amp plug. Wire gauge is an important factor in electrical safety and the thicker the wire the more amperes it can carry. Fortunately, converting a 30-amp plug into a 20-amp plug doesn't create any safety concerns because the wires connected to the 30-amp plug are more than capable of taking 20 amperes.
Things You'll Need
- 20-amp fuse
Remove the plug from the wall socket. Use a screwdriver to remove the cover on the plug so you can access the 30-amp fuse.
Pry out the 30-amp fuse from the fuse holder using a screwdriver. Insert the screwdriver into the end of the fuse and lift up the fuse. Remove the fuse using your fingers.
Put in a 20-amp fuse. Push down on the fuse using your fingers so it clips in place.
Replace the plug cover. Use a screwdriver to tighten the screw so the cover is secure. Insert the plug into the wall socket.
