2020-4-28 · If you're wiring a 220v, 20-amp outlet to run power tools, you can use the same 12-gauge wire you would use for a 110-volt, 20-amp circuit. Remember that the cable must have an extra hot wire . If the appliance draws 30 amps, you need a different type of receptacle, and the cable needs to be 10- gauge .

Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current). So, when we talk about these values, we're really describing the movement of charge, and thus, the behavior of electrons.
