Define "marine grade" wiring

[Rhadley]

What type of wiring is good in a boat? I assume the copper should be plated with silver or tin? Should the insulation be teflon?

Re: Define "marine grade" wiring

As I understand it, RHadley, marine grade wire is made with many small strands of tin plated copper for greater flex and corrosion resistance.<br /><br />As for the insulation, it is also very flexible. Looks and feels like rubber but is probably a synthetic.<br /><br />Good luck.
