Circuit protection

-

This light can be wired directly to the battery feed terminals because this design has resistors built in to the PCB board to protect it. However when fitting electrical components that have a high current draw and involve a motor, pump or heating element, use additional circuit protection, for example a circuit breaker or an in-line fuse holder with the correctly rated fuse. If any installati­on involves running wires through bulkheads use grommets to protect the insulation. Avoid running wires through bilges and note that short circuits can be caused by a breakdown to insulation caused by chafing, exposure to UV light or fuel/oil contaminat­ion.
