What can be the consequence of improper wire sizing in a marine application?

Improper wire sizing in a marine application can lead to short circuiting and fire hazards. When wires are not adequately sized for the current they are expected to carry, it can result in excessive heating due to higher resistance. This overheating can ultimately cause the insulation on the wires to melt or degrade, increasing the risk of short circuits. If a short circuit occurs, it can lead to an electrical fire or damage to the equipment and the vessel itself. Proper wire sizing is crucial to ensure safe operation and to prevent dangerous situations that could compromise the safety of the boat and its occupants.
