In this video, I show you how to install a 220-volt outlet using 4 “wire” The fourth wire is neutral (white wire). Most dryer wires will be a 10 gauge wire for 30 amps. However, the wire shown in the video was a #6 wire for a 40 – 50 amp.
Please watch my video on how to install a 220-volt outlet (20 amp) and my other article on just wiring a dryer.

How to Install a 220 Volt 4 Wire Outlet
Comments ( 38 )
I have two 220s in my kitchen and one I’m not using. I want to run that one to the laundry room for my dryer. Laundry room might be 15 feet away. How do I go about doing it? Would I need to go underneath the house and run the wire through the floor where the dryer will be? My breaker box is outside (old house) and the extra 220 that’s in the kitchen is wired there.
Well dryers need a 30 amp line. Chances are that the 220 line you have is only 20 amp so that wouldn’t work for you.
Can you use 110 volt wires to hook up electronic stove
Most if not all wire is rated for 600 volts. It’s the amperage you need to be concerned with. So a quick answer to your question for the wire I think you’re talking about, no.
Can you use 110 wires to hook up a 220 for electronic stove if it has 3 wires
Nope, not at all.
how would this apply for a hot tub, i am running 4 8 awg wire from a 50amp fuse to a sub panel then to the tub. i have the red and black off the fuse white common and green ground. My question is at the sub panel there is another 50amp do i put a red and black on both sides and then the other red black to the tub i match or do i match both red on 1 side and both black on the other. thanks
White is neutral, the return path for a 220. Black is hot and so is red. the two hots don’t have to match color but they both need to be hot from the two separate hot legs.
can i install a subpanel in the garage of a another subpanel i need 50 am ps to run a air compressor and lights and some electrical i have 3 8ft lights and 4 4 ft lights now there is only 120v going out to the garage from the subpanel now. i know i need a new sub panel in the garage how can i do this the main box is in a bedroom rated at 150 amps and the subpanel is in the florida room now it controls the electrical in the florida room and 120 to the garage. this subpanel in the florida room has room that i can add 4 more circuits. or do i need to upgrade the main panel to 200 amps and run the garage panel from the main panel in the house
You would really need to start adding up all circuits in order to know if a upgrade is even needed. I would just install a new sub panel from the main panel to the garage.
I just bought a new dryer. Upon delivery it didn’t work. The repairman sent by the manufacturer didn’t find anything wrong with the dryer, but the voltage was weird across the plug connections when plugged in. (Black was 240v, Red was .75v). I find that the neutral is not connected at the breaker box. My question is how did my old dryer, also a 4-wire plug, work for 10+ years without it, and why would the electrician who wired the house leave it unattached. Can I just hook up the neutral without doing any damage? I’ve verified that the outlet is correctly wired with all 4 wires.
What you need to do. Unplugged, check voltage across the two hots, red and black. You should between 220-245 volts. And 120volts across each hot to the neutral.
How did it work before, I would have to assume it’s because of the ground. Just make sure that is connected in the panel
My builder installed 220V 30 amp 4 wire plug and breaker. I needed a 20 amp plug for my 5 hp 220V air compressor, so I’m changing it out, but the plug only has the two hots and the ground. Can I just connect the red and black and ground and install a cap on the white/common? Is it required to change the 30 amp breaker to 20 amps?
As long as you don’t need the neutral.
Hello & thank you for you Sharing the wisdom in electronics wiring I’m looking to Provide battery back up power and free energy generator power provide battery back up power and free energy generator power wired straight into my 100 amp Fusebox using a 100 Amp Double Pole Breaker , the batteries will have an Inverter or 2 totaling about 6-7000 Watts continual but my generator Will be a car alternator bypassing the DC conversion will be using straight AC current straight off the stator , how to add a neutral wire into this ? The power sauce only has positive a negative ?
An alternator can not provide you will a neutral. If you don’t need a return path than a neutral shouldn’t be needed. I think about using that ground perhaps.
My question is about breakers. I notice all the 240v breakers in my box have only one switch and not two, for example my dryer and range. But according to your videos this will require a double pole breaker. What is the difference in these breakers?
Also, if you have a double pole 30amp breaker, does that mean it will allow 30amps for each hot leg?
Thank you.
for a 220 breaker you should have a two pole breaker. But the two poles are tied together as one. Send me a picture if you like using the contact Dominick on the bottom of this page. And yes a 30 amp breaker will only allow 30 amps across both legs as one breaker.
on a 220 volt. is the gray wire a neutral wire i have 1 black 1 red 1 gray and 1 clear wire
This would depend on the amperage. white-neutral black or red and black- hot and one ground. Ground could either be bare or green.
