  • Typically a v/30 amp Dryer circuit would utilize 10/3 with ground. run you would want to up-size the wire to #8 copper, to maintain voltage.

    Installing a 30 Amp Volt Dryer Circuit, Wire Size for Dryer, Electric Dryer Circuit Cable, Receptacle Outlet for a Dryer. Electrical Question: What is the Right Wire Size for a Volt Clothes Dryer? I am installing an electrical circuit for a 30 amp volt dryer.

    Wire a Dryer Outlet, I can show you the basics of dryer outlet wiring. How to wire a 3-prong dryer outlet and a 4-prong dryer outlet.

    To be safe, I would probably go with the 8 AWG wire and make sure all the power ends up drying clothes, not heating the wires. I based the text of the answer v on the table heading to avoid confusion. In the example in the picture the dryer doesn't have color designation on the wires, follow direction above; if the dryer cord does have colored wires, white is the neutral wire to the center connector, the red and black wires are the hot live wires which connect to the 2 outer connections of the dryer terminal block, don't forget the ground strap or green wire jumper from the center connector to the dryer frame. Installing a volt dryer circuit should be done according to local and national electrical codes with a permit and be inspected.

    Wire a Dryer Outlet

    The neutral white and the bare ground wire MUST be on there designated connection. In the diagram above the bare ground is indicated by a green line. The bare wire should also be grounded to the electrical box if metallic.

    Be sure to use the properly rated electrical box designed to be used with a dryer receptacle. The breaker used must be a dual double 30 amp v breaker. If you were to measure the voltage between a red lug and a black lug they are not really those colors in the panel, just used here for explanation purposes , you would measure v, if you were to measure between a black bus lug and a ground or neutral bus, you would measure v, and the same would hold true if you measure between a red bus lug and the ground or neutral bus.

    The ground bus is a terminal block with many small holes where the bare ground or green wire can be connected and tightened into place with a screw. The neutral bus is a terminal block also with many small holes where the white neutral wire can be connected and tightened into place with a screw.

    A breaker designed to be used with v, is a dual double breaker that actually when mounted into the panel connects to both phases of the incoming power , in other words connects to both the red and black panel lugs colors in illustration, your panel is not colored but will be alternating between phases from one lug to the next. Sometimes in some panels you may have a set of 4 breakers molded together and they mount in the panel over the 2 lugs , the middle 2 breakers would be the 2 30 amp breakers and the outer 2 could be 15 or 20 amp breakers for use in general purpose v circuits.

    Please note, electrical panels are dangerous to work in, never touch any of the main bus lugs in the panel, they can kill! A breaker can be installed without physically touching the bus lugs. To be even safer you can switch the main breaker off to de-activate the panel which installing the breaker, use a second person to help with a flashlight if needed. Also note that a dual breaker has both breakers bridged so that one of the dual breakers will also trip the other side if it where to trip off.

    The ground wire connects to the ground bus. Just look where all the other bare ground wires are going in the panel. The white neutral wire gets connected to the neutral bus. Just look where all the other white wires are going in your panel. Should be on its own connection screw hole within the neutral bus. The red and black wires from dryer cable connect to the dual 30 amp breaker, one to each of the dual breakers. Photo used with permission from Jeff Worrall at Appliance Aid. This picture above shows a dryer cord at the dryer end with 3 wires only, No ground wire.

    The center wire of this cable is the neutral wire and the outer wires are hot live wires. The hot wires connect to the outer 2 connections the power terminal block of the dryer, does not matter which is which as long as one hot is connected to each of the outer terminal connectors. The center wire neutral wire of the cable goes to the center connector. Since in this case the neutral serves as a neutral and a ground connection, a jumper band ground strap is also connected to the center terminal and to the frame of the dryer.

    A green wire could also be used to connect the center connector to the frame of the dryer. In the example in the picture the dryer doesn't have color designation on the wires, follow direction above; if the dryer cord does have colored wires, white is the neutral wire to the center connector, the red and black wires are the hot live wires which connect to the 2 outer connections of the dryer terminal block, don't forget the ground strap or green wire jumper from the center connector to the dryer frame.

    Photo used with permission from Jeff Worrall at A ppliance Aid. A 4 wire dryer cord contains a black, red, white and green wire. The red and black wires are hot live wires and get connected to the 2 outer connectors on the dryers power terminal block, doesn't matter which is which as long as it is the outer two connectors.
