Question B-003-017-010

Why are fuses needed as close as possible to the vehicle battery when wiring a transceiver directly to the battery?

Correct Answer

To prevent an overcurrent situation from starting a fire

Explanation

Fusing at the source protects the entire length of the wire. If a short circuit occurs anywhere along the wire, the fuse blows quickly, cutting off current before the wire overheats and potentially starts a fire.
