If you exceed 15 amps, the breaker will blow, and protect the receptacle. Click to see full answer.
How many amps can a 20 amp breaker support?
While it allows electricians to add 15 and 20 Amp outlets to 20 Amp circuits, it prohibits them from adding receptacles that exceed 15 amps to 15 Amp circuits.

Will a 20 amp GFCI trip a 15 amp breaker?
Oct 21, 2020 · First off, connecting a 20 Amp load to a 15 Amp circuit will overload the circuit but shouldn't cause a fire because the 15 Amp breaker will trip. A 20 amp GFCI doesn't pose any threat just by being there. The threat comes from people thinking it's on a 20 amp circuit and loading it as such.... which will trip a 15 Amp breaker.

How many outlets can be added to a 20 amp circuit?
If you’re only concerned with the opinion of the NEC, it is quite clear on this issue. It has a table which shows that 15 and 20 Amp outlets can be added to a 20 Amp circuit.

But if the breaker fails to respond, the wires will overheat, causing a fire. This is why the NEC frowns upon the practice. It doesn’t want outlets on 15 amp circuits to exceed 15 amps.
What happens if you force a circuit to carry more current than its rating permits?
If you force a circuit to carry more current than its rating permits, the excess heat generated will melt the wires, starting a fire. Of course, most people trust their circuit breakers to intervene in such situations, tripping to prevent the continued flow of power before it can cause harm.
Can you overload a NEC circuit?
You can add as many outlets as you want. The NEC doesn’t provide any guidance on this issue. However, you shouldn’t overload the circuit. Do not attach appliances whose total draw exceeds the rating of the circuit.
Why can't I connect a 20 amp outlet to a 15 amp circuit?
As I understand it, the reason that a 20 amp outlet can't be connected to a 15 amp circuit is that someone could potentially connect a 20 amp device, overload the circuit, and cause a fire. That makes sense. Now, here's the question.
