The most common electrical outlet in any home is a 110 volt. Sometimes you may hear 110 volt plugs referred to as 120 volt. Do not be confused by this; think of them as one and the same.
Is my outlet 110 or 220?
That means a 220V plug has to have an extra hot terminal, which is brass by convention. Also by convention, the hot wires are colored black and red. A 110V outlet (and plug) has only one hot terminal, and the hot wire is always black. Another key difference between 110 and 220 circuits is the wire size.

The common voltage in a U.S. home is rated at 120 volts. Except for a specialty outlet, such as for a stove, larger BTU air conditioners or some electrical clothes dryers, virtually every other wall outlet will be a polarized two-prong outlet with a third-prong grounding plug.
How do I know if my outlet is 15 or 20?
Look at your outlet. If the two slots are parallel, it is a 15 amp outlet. If one slot is ‘T’ shaped and the other is straight, it is a 20 amp outlet that will also accept 15 amp plugs. If the two slots are perpendicular the outlet is 20 amp only.
How do you tell if an outlet is 120 or 240?
Locate the breaker in your electrical panel that is connected to your thermostat. If you see a single breaker switch like the one shown in the picture below, you likely have 120V. If you see a double breaker, like the pictures shown below, you likely have 240V.

What is a standard 120V outlet?
The modern 120-volt power outlet has three holes: two parallel rectangular slots—one connected to the “live” wire and one connected to the neutral wire—and a round hole for the ground wire. Most outlets are “duplex” receptacles, with two places to plug in electrical devices.
What is 20amp outlet?
20-amp receptacles have a horizontal slot branching off one of the vertical slots. Appliances, such as microwaves, often have 20-amp plugs and must be plugged into a 20-amp outlet. A 20-amp circuit, protected by a 20-amp breaker or fuse, must be served by 12-gauge or 10-gauge wire.
What is 20amp wire?
Why Wire Gauge Is Important Wire Use Rated Ampacity Wire Gauge Low-voltage lighting and lamp cords 10 amps 18-gauge Extension cords (light-duty) 13 amps 16-gauge Light fixtures, lamps, lighting circuits 15 amps 14-gauge Kitchen, bathroom, and outdoor receptacles (outlets); 120-volt air conditioners 20 amps 12-gauge.
Can you use a 15amp outlet on a 20 amp circuit?
Most household electrical receptacles have a 15-amp rating, but they connect to a 20-amp circuit. You can use a device that has a 15-amp plug with either a 15- or 20-amp receptacle. A 20-amp receptacle is for heavy-duty appliances and power tools, such as air compressors.
How do I know if I have a 240 volt outlet?
How to Identify 240-Volt Outlets? The 240-volt outlets are larger than 120-volt outlets, and they have rounded tops with three or four holes. The top hole of an older three-prong 240-volt plugs looks like a backward ‘L’and the other two holes are diagonally placed on the sides.
