The purpose of this thread is to identify possible issue(s) with installation and operation of LED lights, especially when multiple lights are installed in a single circuit with a larger breaker. It was prompted by a friend’s recent experience with LED lights resulting in two fires on his boat. On two separate occasions the LED lights/circuit caused wires to burn (fire, not just smoke) on a Carolina Skiff Sea Chaser with lights from an unidentified manufacturer. The fires were extinguished prior to causing significant damage though for one fire five fire trucks, two EMS vehicles, plus sheriff and police cars showed up. Per the owner, the LED deck lights and wiring were original equipment. Multiple lights are wired in parallel on a 15 amp circuit. One LED light failure could have been caused by a gaff incident but the other appeared to only have salt water intrusion in an otherwise non-damaged fixture. Like many boats, the lights were installed in a circuit with a 15 amp breaker and with wiring presumably suited for 15 amps. However, the wire leads to the LED light were probably not suited for 15 amps since a typical LED deck light’s current draw is <0.25 amps. Note a 15 amp breaker is 60 times the current draw of one typical LED light. Even if 10 lights are used in a circuit, the current draw is less than 3 amps. If a circuit board were to degrade and draw say 10 amps through a smaller gauge wire lead, it could cause the wire lead and/or circuit board to greatly overheat causing the wire insulation to melt or flame up; all without tripping the breaker! Bottom line, for circuits, especially with multiple LED lights which might warrant a larger breaker, the breaker needs to be appropriately matched (probably 5 amps or less) and small enough to trip prior to overheating a single, smaller gauged wire lead. If we Shamrock owners with old style lights upgrade, we need to remember to drop the breaker rating accordingly. Questions: 1) How are your LED's holding up? 2) Have you heard of similar LED failures?
