4-prong dryer outlets are simple enough to wire if you have the proper material and tools to do the job. You'll need at least a few of the following things to accomplish this task:
- Drywall Screws
- Wire Strippers
- Razor Knife
- Linesman Pliers
- 240-volt, 4-Prong Dryer Outlet
- 10-3 With Ground Nonmetallic Sheathed Cable
- 2-Pole, 30-Amp Circuit Breaker
Run a New Feed
If your home is not already wired for a 4-prong outlet or if the feed is not equipped with two hot wire, a neutral, and a ground wire, you'll need to run a new wire to feed the outlet. Install a 10-3 NM wire that has a ground wire included from the breaker panel to behind the dryer. Leave enough slack at each end to allow for proper connection.
Mount The Dryer Outlet
Remove the dryer outlet cover and remove the outlet electrical connection knockout. Install the nonmetallic sheathed cable into the outlet box, tighten the cable clamp, and attach the outlet to the wall.
Wire The Dryer Outlet
Strip the red and black wires and install the in the outer two connection points of the outlets, which is the two hot feeds of the outlet.
Now strip and connect the white wire to the neutral connection, which is the terminal screw with the "L"-shaped terminal.
Connect the bare copper ground wire to the ground terminal, which is the round terminal.
Replace the dryer outlet cover plate and tighten the mounting setscrew.
Connect The Wire To the Breaker
Connect the red and black wires to the 2-pole, 30-amp breaker, the white wire to the neutral buss and the bare copper ground wire to the grounding buss.
Turn on the breaker and test the outlet with a voltage tester or a digital multimeter.
- Be sure you install 10 guage wire. It is rated for 30 amps.
- You'll need a 2-pole, 30-amp breaker to feed this outlet.
- Place the outlet near the dryer because dryer cords come in four, five, and six foot lengths.
