Wiring a dryer Wiring a v Dryer. Circuit Breakers. Electrical wire. Electrical Wiring Codes. I have a dedicated volt dryer outlet which has the older two hots and a neutral.

There is no ground wire going back to the panel. Is there any way I can legally ground the outlet so as to convert it to the newer 4-prong 2 hots, 1 neutral, 1 ground? Use a grounding rod on the other side of the wall, or a cold water pipe, for example? Hi Mike, If the dryer circuit goes directly back to the main electrical panel then the neural wire should be bonded to the ground system, however this should be verified by a licensed electrician.

If the home ground system is not up to NEC code standards then this would be a good time to make this important improvement. Please see the wiring diagrams in this post which will assist you with the wire connections once the ground system has been evaluated. I have a 3 wire outlet box for my current dryer and a 4 wire outlet box for my new dryer. Can I still use the 3 wires Black, White, Copper in the 4 wire box? Hi Hilton, Please check with the owners manual for the new dryer to see if it may be wired with the three wire system.

Some new dryers require a dedicated neutral, which in that case would require a 4-wire circuit. I hope this helps, Dave. I have a 3 prong dryer outlet but there are 4 wires red black green white the red and black on the sides and green connected to the bottom but the white is not connected, so will that not make the dryer work or is that in case I need to switch to a 4 prong.

Hi Rich, Depending on the age of the home, some dryer circuits are wired with a 4wire circuit, and it could be that the last dryer had the 3wire hookup and the outlet was changed to be a 3wire outlet. This can be verified by inspecting the dryer outlet wiring, and if that is the case then it would be best to replace the 3wire outlet with a 4wire outlet and make sure to connect all 4 wires accordingly. Some newer dryers will allow converting from a 4wire cord to a 3wire cord, but that needs to be verified with the information about the exact dryer that you have.

Please refer to the links in the above information that will lead you to the dryer wiring diagrams.

Electric Dryers: Connecting a 4-Wire Power Supply Cord

The power source is coming in from the left. Notice the black wire is the only wire that we are controlling through the 2-way switch. You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2-way switch and a black wire from the other screw on the 2-way switch going to the load light, ceiling fan etc.

The white wires are wire nutted together so they can continue the circuit. Just use your mouse pointer on this diagram and follow the current flow from black wire hot wire through the 2-way switch, then to the load and return through the white wire neutral. This should give you a good basic understanding how the 2-way switch circuit works and will help you in adding or changing a 2-way switch.

How a 3-Way Switch Circuit Looks. So the circuit above when explained should give you a good concept on how this 3-way circuit works. When wiring a 3-way switch, this image on the left will show how the connections should actually look when all connections are made.

The best way to simplify wiring a 3-way switch is this. By looking at the moving 3-way switch above, the hot black wire coming from the power source will always attach to the common screw on the 1st switch in the circuit. Then the traveler wires are connecting both switches and it does matter which wire goes to which traveler screw.

Now with that said, just look at the switch again and look at the circuit. There you have it, 3-way switch wiring simplified. It's very important that the ground or bare copper wire is connected to the green screws on the switches.

The second is a amp dedicated circuit for running an electric dryer. The third is a standard amp lighting circuit that likely supplies light fixtures in other rooms as well as the laundry area. The volt, amp circuit supplies a receptacle for the washing machine.

It is typically wired with gaugetwo-wire cable containing a hot wire, a neutral wire, and a ground wire. The receptacle is a amp GFCI receptacle. What's special about this circuit is that it is a designated circuit, not to be confused with a dedicated circuit. While a dedicated circuit supplies only one appliance, a designated circuit is intended for single-use, not necessarily a single appliance.

The "use" in this case is laundry, and you can plug both a washer and a gas dryer into the same receptacle. Of course, if you're set up for a gas dryer, you won't need the volt dryer receptacle we'll discuss next.

Electric dryers run on both volt and volt power. The V is for the dryer's heating element. The V is for the timer, clock, buzzer, and other bells and whistles. If you buy an electric dryer today, it will require a special appliance cord with a four-prong plug. And that's our next laundry room circuit. The circuit is protected by a amp circuit breaker. Older dryers typically had three-prong cords that fit only three-slot receptacles.

A laundry room would be pretty hard to use without a circuit for lighting. As mentioned, light fixtures in laundry rooms are likely to be on the same circuit as the lighting for an adjacent room or hallway. Standard lighting circuits are amp circuits and often include general-use receptacles as well.

This includes the amp designated receptacle for the washer and gas dryer, as applicable and any general-use receptacles. GFCI protection is not required for a amp electric dryer receptacle. When laundry rooms are finished with drywall or other finish material, receptacles typically are installed in the normal fashion, with the electrical boxes recessed into the wall and with NM cable running to the boxes.Gas clothes dryers and electric clothes dryers have much different electrical needs.

A gas dryer produces heat by burning either natural gas or liquid propane LP gas, and it uses volt electrical currently merely to spin the dryer compartment and run the controls. A gas dryer plugs into an ordinary volt electrical outlet, and it has a cord fitted with an ordinary appliance plug. An electric dryer, on the other hand, heats the air with electric heating elements and runs on volt current, which requires a much different outlet receptacle and a special heavy-duty appliance cord with a unique plug.

But there are two different outlet styles and plug-in cord styles used for these volt electric dryers. Some have three slots, designed to accept appliance cords with three prongs, while other outlets have four slots, designed to accept four-prong cords. There are so many of both kinds of dryer outlets in homes throughout the U. S, that newly purchased clothes dryers usually come with no cord at all, which allows you to choose and install a cord that matches whatever kind of dryer outlet found in your home.

In this configuration, the ground connection on the dryer was bonded to the neutral connection, so that the single wire served both functions—as the neutral current pathway and as the grounding pathway. This didn't mean that the appliance wasn't grounded, but only that neutral wire also served as the grounding pathway.

This is normally not a problem, since neutral wires are always grounded in the main service panel. Under some unique circumstances, though, there is a very small chance of shock with this configuration. Therefore, since the s, the NEC and standard local code practice have mandated that new installations must include four-slot dryer outlets for volt dryers, and that dryers must be fitted with four-prong cords to match them.

However, there is no mandate that requires homeowners to stop using or convert existing three-slot dryer outlets. The risks are so small that the code allows existing three-slot outlets to remain in place for homeowners to use.

If you buy a new dryer but have only an older three-slot outlet, it's fine for you to install a three-prong cord to match that outlet.

Since the s, standard wiring practice and the NEC has directed that volt dryer outlets should have a four-slot configuration, in which the neutral electrical pathway and the grounding pathway are carried by separate wires. This came about because it was gradually recognized that the frequent presence of water in the laundry area created the potential for shock unless a separate, dedicated ground pathway was also present in the dryer.

A four-slot receptacle, four-prong plug configuration is therefore somewhat safer than the older three-slot, three-prong method, since it has a dedicated grounding pathway that serves no other function. You are no longer allowed to install a three-slot dryer outlet, and if you move into a home with the newer four-slot outlet, your old three-prong dryer will need to be refitted with a four-prong cord.
