Frequently Asked Questions

AI
Tinned copper is essential for marine environments because the tin coating prevents corrosion from creeping up the wire strands, which would otherwise increase resistance and lead to overheating.
Gauge selection depends on the current (amperage) the wire will carry and the length of the run. Lower gauge numbers indicate thicker wire capable of handling higher loads over longer distances.
It is not recommended. Automotive wire lacks the corrosion-resistant tinned copper and specialized insulation required to withstand the moisture and salt exposure typical of marine settings.
