As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
The National Electrical Code (US) allows up to thirteen 20 amp receptacles on a 20 amp circuit. 120V x 20A = 2400 VA each duplex receptacle is calculated at 180 VA 2400 / 180 = 13.3333 receptacles, since you can't put a third of a receptacle in, you have to round down to 13.
If only two wires are available for the circuit and the switch requires a neutral wire, you may need to run a new wire that includes a neutral to properly install the switch. It is important to ensure all wiring is done in accordance with local electrical codes to maintain safety. If unsure, consult a licensed electrician for assistance.
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.
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.
Yes, you can convert a 3-prong 240V outlet to a NEMA twist lock 20A style outlet, although you may need to rewire the circuit. The twist lock outlet typically requires an extra ground wire in addition to the hot and neutral wires. It is important to follow electrical codes and guidelines when making any changes to electrical outlets for safety reasons.

Need to know what the voltage is. A NEMA number of the pin configuration would also help.

20a + 45 = 5(4a + 9)
From your description, this sounds like it is a sine wave offset to 10A, so the peak is at 20A, and the min is at 0? For this case, you have 10A DC (RMS) wave and a 10A Peak - neutral AC wave; The RMS value of the AC wave is: 10/2*sqrt(2) = 3.54A. So the RMS amplitude of this wave is 13.54A.
