How to Change a 220 Outlet

A 220-volt outlet is typically found in a home behind a dryer, as some electrical dryers require a 220-volt power input to function properly. If the plug on the 220-volt outlet breaks, or if you buy a new dryer and require a different type of plug, then you have to change the outlet. This can be a dangerous process if you don't follow the proper safety procedures, but once those hurdles are passed, you'll be able to change out the outlet in just a few minutes.

Things You'll Need

• Flat-head screwdriver
• Replacement 220 outlet

Instructions

1. Go to the circuit breaker and locate the outlet circuit, which is a two-pole breaker that should have a label next to it. Turn off power to the entire house if you can't determine which circuit is for the outlet you're replacing.

2. Detach the outlet cover using the flat-head screwdriver, then unscrew the outlet from the wall box using the screwdriver. Pull the outlet out of the wall box and turn it to the side so you can see the wires on the back.

3. Loosen the wires running to the back of the outlet using the screwdriver. Keep the wires from touching each other by pulling them away with your fingers.

4. Place the replacement outlet in your hand and connect the wiring from the wall to the outlet, using the screwdriver. Connect the black wire from the wall plug to the brass screw on the replacement outlet, using the screwdriver. Connect the white wire from the wall plug to the silver screw on the replacement outlet, using the screwdriver. Connect the green wire from the wall plug to the green screw on the replacement outlet, using the screwdriver.

5. Secure the replacement outlet into the wall box, using the screwdriver. Attach the outlet cover with the screwdriver. Turn on the breaker in the circuit breaker panel, then plug in your dryer or other appliance.

Tips & Warnings

• Always make sure the circuit is not live before changing out the outlet, otherwise you risk electrocution. If you're not sure, get a multimeter and test the circuit to make sure it is not live.
