Can I use 14 AWG on 20amp circuit?
14 AWG must be protected at 15A, according to NEC 240.4(D)(3). 14 AWG can’t be used on a circuit with a 20A breaker. The screw terminals are the better choice if you want to put 15 Amp receptacle on a 20 Amp circuit with 12 gauge wire. You can use the side terminals.
What is the maximum size circuit breaker for #14 copper wire?
15 amp

What size wire do I need for a 20 amp circuit breaker?
The National Electrical Code requires circuits protected by a 20 amp circuit breaker to use #12 AWG copper wire throughout the circuit. The National Electrical Code allows circuits protected by a 15 amp circuit breaker to use #12 AWG copper wire but #14 AWG wire cannot be protected by anything larger than a 15 amp breaker for power and lighting.
Is 14ga wire allowed on 20 amp circuit?

What happens if a circuit breaker trips on 14 wire?
In a case of a short circuit, the breaker would trip, but what usually happens years later someone wants to feed power for something else and seeing 14 wire, continues to run 14 through rest of circuit while someone is using blow dryer for example and can result in a formula for potential fire hazards.
