Calculations are based on 105°C wire. For wire rated at 90°C or lower, or for wire that passes through an engine room, the first row of the chart does not apply. d) Intersect the CURRENT FLOW IN AMPS with CIRCUIT LENGTH to identify the correct wire size Example: A windlass rated 80A is 25 ft. from the battery. The circuit length is the total length of the positive and negative wire added together, which in this example is 50 ft. The circuit type is ‘non-critical’, and the correct wire size is 4 AWG. Calculations are based on 105°C wire.
