When would you use a 20a outlet?

Since a majority of 125vac consumer products, commercial equipment and light industrial machinery require less than 15A, 15A plugs are provided on their power cords as well. The NEC requires that a 20A receptacle is installed on a 20A branch circuit when there is only one receptacle connected to that circuit.

Similarly, you may ask, what is a 20 amp outlet used for?

You can use a device that has a 15-amp plug with either a 15- or 20-amp receptacle. Standard 15-amp receptacles are suitable for typical household appliances, lamps and other accessories. A 20-amp receptacle is for heavy-duty appliances and power tools, such as air compressors.

Additionally, can I replace a 15 amp outlet with a 20 amp outlet? A 20 Amp breaker does not adequately protect a 15 Amp outlet. The breaker is supposed to pop instead of, or before the house burns down. Even in the very unlikely event that you have 20 Amp wiring, the appliances plugged into the 15 Amp outlet need to be protected with 15 Amp breakers.

Thereof, do I need 15 or 20 amp outlets?

Electrical plugs designated as 20-amp will not fit into 15-amp outlets. A 15-amp circuit is usually served by 14-gauge wire and is protected by a 15-amp circuit breaker or fuse. A 20-amp circuit, protected by a 20-amp breaker or fuse, must be served by 12-gauge or 10-gauge wire.

What happens when you put a 20 amp receptacle on a 15 amp circuit?

If your question is “can I connect a receptacle rated for 20 amps to a circuit designed for 15 amps?”, the answer is yes, because the receptacle can handle more current than the circuit is rated for. If you exceed 15 amps, the breaker will blow, and protect the receptacle. The inverse is not true.
