Ampacity Charts. Amperage is a measure of the electrical current flowing through a circuit. Current is measured in amperes or . You must use the correct size wire for the amperage requirement of the circuit to prevent the wire from over heating. The number and type of electrical devices connected to a circuit determine the amperage requirement of the circuit. Usually, a general purpose house circuit is designed for 2.
Lighting circuits may be designed for only 1. 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, 1.
