How To Convert 3 Wire Dryer Electrical Outlet to 4 Wire

  • Unscrew and remove the cover plate from the outlet box
  • Loosen the screws that hold the grounding strap or wire to the outlet box
  • If there is a green screw, it is probably for the ground wire
  • Pull the grounding strap or wire off of the green screw and push it out of the way
  • Cut off the ends of the three wires that are sticking out of

Convert 4 Wire to 3 Wire

If you have an electric dryer that is four-wire but your home is only wired for three, never fear! You can easily convert the dryer to work with your existing wiring. Here’s how:

First, turn off the power to the circuit breaker that controls the outlet where the dryer is plugged in. Then, unplug the dryer from the outlet. Next, remove the plate on the back of the dryer where the cord is attached.

Inside, you will see four wires: two black (hot), one green (ground), and one white (neutral). The black and red wires are your hot wires, so they should be attached to the brass terminals. The green wire is your ground wire, so it should be attached to the green terminal.

And finally, since we’re converting from a four-wire setup to a three-wire setup, simply cap off or tape over the unused white neutral wire and attach it to nothing. Now replace the plate and reattach your dryer cord to its proper place. Finally, turn on power at the breaker box and test out your newly converted three-wire electric dryer!

How to Wire a 4-Prong Dryer Outlet

If you’re installing a new dryer in your home, or if you’re replacing an old one, you’ll need to know how to wire a 4-prong dryer outlet. This type of outlet is commonly used in homes built after 2000, and it provides a separate ground connection alongside the hot and neutral wires. Wiring a 4-prong dryer outlet is not as difficult as it may seem—you just need to follow some basic safety precautions and have a little patience.

Here’s what you’ll need to do: 1. Turn off the power to the circuit that will be supplying electricity to the dryer outlet. Use a circuit tester to make sure that the power is off before proceeding.

2. Remove the cover plate from the electrical box where the dryer outlet will be installed. Take note of how the current wires are configured and which screws they are attached to—this will make it easier to install the new wires later on.

Next, remove the plate on the back of the dryer that covers the cord connection. Once that’s off, loosen the terminal screws that hold the three wires in place (black, white and green). Gently pull the wires out of their respective terminals – taking note of which wire goes where – then disconnect the old cord from the dryer.

Now it’s time to connect the new 4-prong cord. Begin by attaching it to the green ground screw, then move on to attaching each of the black, red and white wires into their proper terminals. Finally, screw on the new strain relief plate and give everything a once-over before plugging your dryer back in and flipping on the power switch!

Does a 3 Prong Dryer Outlet Have to Be Grounded?

Yes, a 3 prong dryer outlet must be grounded in order to work properly and safely. The grounding helps to protect against electrical shocks and fires. If your dryer outlet is not grounded, you should have an electrician come out and fix it as soon as possible.

Can You Put a 4-Wire Dryer Cord on a 3 Wire Dryer?

If you have a 4-wire dryer cord and a 3-wire outlet, you can connect the dryer cord to the outlet by following these steps: 1. First, twist together the ground wires from both the cord and the outlet. Then, screw on a wire connector to hold them together.

2. Next, twist together the neutral wires from both the cord and the outlet. Again, screw on a wire connector to hold them together. 3. Finally, twist together the two hot wires from the cord and outlet.

Make sure that you connect the red wire (the “hot” wire) to the brass terminal, and connect the black wire (the “neutral” wire) to the silver terminal. Once they’re twisted together, screw on a final wire connector to hold them in place.

What are the 4 Wires on a Dryer Plug?

If you have ever looked at the back of a dryer, you may have noticed that there are four wires protruding from the dryer plug. These four wires are what provide power to your dryer. The two outer wires are known as the hot wires, while the two inner wires are known as the neutral wires.

The hot wire carries electricity to your dryer while the neutral wire returns it back to the panel. The reason there are two hot wires is because most homes in North America have 240-volt power. This means that each leg of your home’s electrical system is providing 120 volts.

In order for your dryer to work properly, it needs to be able to draw enough current from both legs of the system. That’s why there are two hot wires carrying electricity to your dryer plug. If you were to cut one of the hot wires, your dryer would still operate but it would only be drawing electricity from a single leg of your home’s electrical system.

This can put a strain on other appliances that share that same circuit and could potentially cause problems down the road. So if you ever need to replace a dryer cord or plug, make sure you get one with four wires so that all of your bases are covered!


If you have a four-pronged dryer cord and are hooking it up to a three-prong outlet, you need to know how to wire it up correctly. The extra prong on the dryer cord is for grounding, and if you don’t connect it properly, your dryer could be at risk for an electrical shock. The best way to wire a three-prong dryer outlet with four wires is to connect the green grounding wire to the green screw on the outlet, connect the black hot wire to the brass screw on the outlet, and then connect the white neutral wire and red hot wire together with a twist-on connector.
