It is important to use the correct cable gauge for the installation. This can be spilt into two sections.
First work out the gauge required from the power source to the junction box, second work out the minimum gauge
needed from the junction box to the lights – these tables are given on page 4.
First, calculate the cable gauge required from the power source to the junction box. The method for doing this is:
1. Calculate the TOTAL CURRENT IN AMPS of the circuit. i.e. number of lights x max current at chosen voltage
2. Find circuit LENGTH IN FEET (or metres) along the left side of the chart. Note that the total length of the circuit
is the ROUNDTRIP distance from power source (usually the battery) to the junction box and back.
3. Read off the cable gauge required for the TOTAL CURRENT for the circuit length.
