If you’re replacing an older dryer outlet, you may find that the new dryer outlet is a 3 prong outlet, but the old dryer outlet was a 4 prong outlet. This is because the National Electrical Code (NEC) changed in 1996 and requires a grounded neutral wire on all installations of dryers. This article will explain how to wire a 3 prong dryer outlet for a dryer that is wired with a 3 prong cord.

Tools and Supplies Needed

Before beginning the installation of the 3 prong dryer outlet, you will need the following tools and supplies:

  • Wire strippers
  • Wire cutters
  • Screwdrivers
  • Grounding wire
  • 3 prong dryer outlet
  • Wire nuts

Safety Precautions

Before beginning any electrical work, it is important to take the proper safety precautions. Be sure to turn off the power to the circuit at the main circuit breaker before beginning any work. Test the wires with a non-contact voltage tester to ensure that the power is off before beginning any work. Wear protective safety glasses and work gloves to protect yourself from any electrical shock.

Removing the Old Outlet

Once you have ensured that the power is off, you can begin by removing the old outlet. Unscrew the two screws on the side of the outlet and remove the cover plate. Loosen the screws on the side of the outlet box and carefully pull the old outlet out of the box. Be sure to note the color of the wires and the position of the wires in the box.

Installing the New Outlet

Once the old outlet is removed, you can begin installing the new 3 prong dryer outlet. Take the new outlet and place it in the box, making sure to line up the mounting holes. Secure the outlet to the box using the screws. Connect the ground wire (green or bare copper) to the ground terminal on the outlet. Connect the white wire to the neutral terminal and the black wire to the hot terminal. Secure the wires to the terminals using the screw terminals. Once the wires are connected, tighten the screws to secure the wires in place.

Wiring the Outlet

Once the outlet is secured in the box, you can begin wiring the outlet. The 3 prong dryer outlet has three wires: a black wire, a white wire, and a green wire. The black wire is the hot wire and is connected to the black terminal. The white wire is the neutral wire and is connected to the white terminal. The green wire is the ground wire and is connected to the green terminal.

Securing the Outlet

Once the wires are connected, you can secure the outlet to the box. Place the cover plate over the outlet and secure it with the two screws. Be sure to tighten the screws securely to ensure that the outlet is securely in place. Once the outlet is secured, you can turn the power back on and test the outlet to ensure that it is wired properly.


Wiring a 3 prong dryer outlet is a simple and straightforward process. As long as you follow the instructions and use the proper tools and supplies, you should be able to complete the job in a few short steps. With the right tools and supplies, you can easily replace an old 3 prong dryer outlet with a new one and ensure that your dryer is properly wired and ready for use.
