The purpose of fuses in electric wiring is to __________.

Correct Answer: Option C — prevent overloading the circuits

Fuses serve as critical safety components in marine electrical systems. By design, they are intended to prevent overloading of circuits. If an excessive current flows through the circuit, the fuse element melts, breaking the connection and protecting the wiring from overheating and potential fire hazards, as required by 46 CFR.
