What gauge wire for boat lights. For safety use only wire that is marked with size and type. Even the experts have to check occasionally on the correct gauge and ampacity maximum amount of electrical current a conductor can carry of wire for a given marine dc load. 8awg is getting toward over kill in most cases for boats under 30ft. The simplest method weve found uses the charts below. Repeat this process for all the boats navigation lights. Connect the 8 gauge unfused wire to the boats common power bus.
Wire the tail marker and license plate lights with brown wire. Even a small boat 3 5 loads wed recommend at least 12awg wire for this. 10awg for larger boats 5 10 loads is normal. Red terminals fit 22 to 18 gauge cables blue terminals 16 to 14 gauge cables and yellow terminals 12 to 10 gauge cables. Select either the 10 or 3 voltage drop chart. The terminals are the weak link in an electrical circuit.
Use 18 gauge wire for all colored wires on four wire trailer connectors and 16 gauge wire on six and seven wire trailer connectors. Cut a piece of stranded copper wire to this length. Marine grade wire is manufactured in multiple gauges for different applications. Remember these are all generalities there are many valid reasons to make exceptions. Trim 12 inches of the cover from a roll of no. Wrap the fused lead from the switch around one of the terminal screws of the light bus.

Blue wires should be 12 gauge on six and seven wire trailer connectors and 18 gauge on four and five wire connectors. Most importantly sae wire is up to 12 percent smaller than american wire gauge awg boat cable which means that in many applications larger gauge wire must be used to stay within the voltage drop limits recommended by experts see our west advisor on marine wire size and ampacity. We suggest you use 12 or 14 awg to minimize your voltage drops or more if the manufacturer suggests it. 50 ft 100 or 200 options available 48 out of 5 stars 169 19951995. Use the charts below to determine the correct wire gauge based on the amount of current in the circuit and the length of the wire run.
