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.
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.
