The selection of the correct gauge for automotive or other low voltage applications is extremely important to maximize safety and performance. Voltage drop or a loss of candlepower can occur if an insufficient gauge is used. Always consider the total amperage and length of wire in each circuit when selecting an adequate gauge. Allow for the return circuit, including the grounded return, when estimating the length. USING THE CHART 1. Measure the length of wire in the circuit including the ground return. A two-wire circuit will be the total lengths of both the wires. Account for both vehicles on auto and trailer applications. 2. Find the total amperes, watts, or candlepower and choose the nearest number in Circuit Amperes column. 3. Look across for proper footage to find nearest wire gauge. Note: 18-gauge applications inside of the shaded area could be 20-gauge for electrical purposes. However, it is recommended to use 18-gauge for the tensile strength of the wire. Chart is based on maximum 10% voltage drop @ 100°F (in free air).
