The guage of wire for 20 amps is #12 copper.
The maximum current rating for a 20A wire gauge is 20 amperes.
12 AWG.

For a 120V 20A motor, you would typically use a 12-gauge wire to ensure it can handle the current without overheating. This wire size is suitable for the amperage and voltage to provide proper insulation and safe operation for the motor.
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
No, you cannot run a 110V 20A circuit off one leg of a GE THQP 220V 20A breaker. A 220V breaker is designed to provide two hot legs, each supplying 110V, but when using only one leg, it does not provide the proper grounding or neutral configuration needed for a standard 110V circuit. Additionally, this could lead to potential safety hazards and code violations. Always consult a qualified electrician for proper circuit configurations.
