Can I use a 20 amp plug 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.Click to see full answer. Similarly, you may ask, can I install a 20a outlet on a 15a circuit?No, a 15A breaker will not trip at 16 amps, at least not for a long time. I can understand why a 15 amp receptacle shouldnt be used on a 20 amp (12AWG) service but a 20 amp receptacle should be able to handle the load safely. But a 15A receptacle CAN be used on a 20A circuit, IF there is more than one.Subsequently, question is, how many 15 amp receptacles can be on a 20 amp circuit? Table 210.21(B)(3) also shows that a 15 amp receptacle can be installed on a 20 amp circuit that serves 2 or more receptacles. Commentary following 210.21(B)(2) in the handbook clearly states that 15 amp receptacles are permitted on a 20 amp circuit. Also Know, 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.Can you put a 20 amp breaker on a 15 amp circuit?The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
