Location: Kingston, Ontario | Cheap wire will not last as long in a boat so likely to not actually be cheaper in the end...as well as the risk of burning everything down. Do not do it on the heavy guage main battery connections.
Marine wire is larger than SAE for the same gage and the copper strands are finer to make it more flexible. The individual strands are tinned to prevent corrosion as well. All good things on a wet vehicle that bounces, vibrates and shakes like crazy.
I would also bet your insurance will be voided if your boat burnt down and they found the wrong electrical installed. |
