3 Wire Dryer Plug Diagram

By | August 19, 2022



Most homeowners who install a clothes dryer find themselves needing to know how to wire a 3-wire dryer plug. The plug is designed to accept two hot wires and one ground wire, as well as an alligator clip that must be attached to the metal grounding strap or screw that is found inside the outlet box. Knowing how to wire a 3-wire dryer plug can save time and money, making it a job that can be completed relatively easily with a few basic tools.

The first step in wiring a 3-wire dryer plug is to find the appropriate circuit breaker for the installation. In most cases, this breaker will be found in the home’s main electrical panel. Once the breaker is located, ensure that it is switched to the ‘off’ position. Then, using a screwdriver to remove the cover plate from the outlet box, remove any old wiring if present. Once all of the old wiring is removed, begin by connecting the two hot wires to the two brass terminals on the dryer receptacle. It is important to ensure that the two hot wires are connected to the correct brass terminals, as this will prevent any potential danger when the circuit is powered on.

Following the safe connection of the two hot wires, attach the ground wire to the green screw that is set into the back of the outlet box. Ensure that the ground wire is firmly secured. Finally, attach the metal alligator clip that was included with the dryer plug to the metal grounding strap or screw that is set into the outlet box. Then, reattaching the cover plate to the outlet box and restoring power to the circuit, the 3-wire dryer plug should now be successfully installed and ready for use.

Knowing how to wire a 3-wire dryer plug is both easy and essential for anyone undertaking a dryer installation. With a few simple tools and a little bit of know-how, it can be accomplished in a matter of minutes. Having the ability to wire a 3-wire dryer plug will not only save time and money, but ensure safety for all involved.
