12 awg is larger.
I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
14 AWG wire has a cross-section of 2.07 square millimetres so can be used up to a limit of 15 amps.
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.
Yes. It is abbreviated as AWG. For example, in residential wiring the size wire to use on a 15 Amp circuit would be 14 gauge or 14 AWG.
AWG 10.
Yes the ampacity of #12 is 20 amps whereas the ampacity of #14 is 15 amps, so you are well within the range using #12 wire.

14 AWG.

14 AWG wire has a cross-section of 2.07 square millimetres so can be used up to a limit of 15 amps.
Yes, if you are using AWG # 10 wire. If you are using AWG # 12 then the answer is no you must use a 20 amp breaker. On AWG #14 wire you must use a 15 amp breaker.
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.
Yes, a #12 AWG conductor has a greater diameter than a #14 AWG conductor. A #12 conductor has an ampacity of 20 amps whereas a #14 conductor only has an ampacity of 15 amps.
Use a 15 amp breaker and 14 AWG wire and all switches and outlets rated at 15 amps or greater.
5. You are probably asking about wire size. 15 amps is typically 14 AWG and 20 amps is 12 AWG.
Yes. It is abbreviated as AWG. For example, in residential wiring the size wire to use on a 15 Amp circuit would be 14 gauge or 14 AWG.
