To calculate the amperage for a circuit, first add up the wattage of all the electrical devices that will be on the circuit. Then divide the total wattage by the voltage of the system, 110 or 220, and that will give you the expected current or amps. By matching load current (in AMPs) across the top of the chart with wire gauge (AWG) down the left side of the chart, one can determine voltage drop per 100 ....
