220 Volt Plug Receptacles Configurations

| January 4, 2012 | 7 Comments

 These outlets are the ones you’re most likely have in your house.

Ok, so lets talk about the types of outlets you’ll find in your house. For the most part you are going to see 120 volts, 15 amp and 20 amp. And 220 2 wire, 3 wire and four wire types.

Please remember not all 220 volt outlets use a neutral (white) wire. To give you a general idea, lets say you just bought a air compressor from Home Depot. It requires 220 volt but the plug only has three prongs. You’ll have the two that look a like will be the two separate hot’s and other round looking on would be the ground. And of course more than likely it would be 20 amp.

Watch my video on how to install a 220v 20 amp video How to install a 220 volt outlet.  Or the 220 4 wire video How to Install a 220 Volt Outlet 4 wire or Dryer Outlet

220 volts 20 amps

220 volt 20 amp

This is a 220v 20 amp outlet as shown in the how to 220 volt outlet video likely to be used this for larger power tools in your garage or shop or perhaps an wall air conditioner.

220 volts 30 amps

30 amp 220v 2 pole outlet

Commonly known as a dryer outlet. Of course used for a clothes dryer. This would be used in a wall box with a cover plate (flush mount)

220 volt 50 amp outlets

50 Amp 220v 4 wire

In a house these would be considered the big boy. You’ll find one of these in newer homes for a stove oven combo. This is a 4 wire outlet. See my video on how to install one of these.

This is 50 amp 220 4 wire. Better know as a stove or oven outlet

Keep in mind, although you might have a oven, dryer, stove or what ever. It may not have an outlet at all. It could be hard wired into the appliance. And that’s fine, lot’s of bigger commercial appliances are know to be wired that way.

Tip… Red is hot (110 volts) black is also hot (110 volts) = 220 volts. White is the neutral and is the returned path back to the transformer on the road. Ground is just that. Ground to the each and is always always used on anything electric. Unless of course your house is very old in which case should be updated just for pure safety.

    Thank You very much for your vids and info on your website. It helped me to safely install a sub panel. I used a 6-3 wire for my panel because of the information from you. I was sure wanting to use the 8-3 just for the cost differance. The safety of my kids dont have a price so 100 bucks more for the wire was a no brainer. Thanks again for the Profesional help.

    Hi, I just moved into a house that has a 4 wire plug like the ‘big boy’ you show here. My dryer has the regular 220 20amp plug. Do I need an adapter or to convert the whole recepticle and run a lower amp connection?
