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

To calculate the watts from amperes and volts, you can use the formula: Watts = Amperes × Volts. For 20A at 110V, the calculation would be 20A × 110V = 2200 watts. Therefore, 20A at 110V is equal to 2200 watts.
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.
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.
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
