Just noticed today that our local Home Depot carries a large assortment of marine grade wire. If you have a wiring project in the works might be worth a look at your local home center to compare to the other guys.
I you consider this wire for marine use it must be tinned copper,(ABYC required), accept nothing less. If it is ANCOR brand you are on the right track. Also the wire should be labeled for boat or marine use.Insurance or C&V survey will note the inferior grade of wire used and reflect that on the survey which in turn will become the attention of the insurance underwriter as possibly a bad risk and/or devalue the boat. Use quality tinned marine wire on any system with good quality connectors (also tinned) not inferior discount store supplied connectors.
is 'UL' labelled "BC5W2" - and in addition to Tin Plated, should be Type 3 Stranding, and 'AWG' sizes.You're very lucky to find a Home Depot with Ancor Marine Wire.
While just about anything will be better than the big marine supply chains, Home Depot, Lowes, etc. isn't necessarily the cheapest alternative.There is a supply house locally that carries marine grade wire (They don't don't carry 2 ought gauge battery) in bulk - you have to buy a fairly large roll, but it is cheaper than HD, et al, and 20% of the marine store price.Insist on tinned wire.
lets not be quite so grandstandish. In our refit, I rewired with marine tinned wire. Much of the old stuff from the 80's was not tinned. It went through 10 years of the tropics and a flooded boat after huricaine Louis. None of the untinned stuff had any type of failure. I would suspect higher resistance in some cuircuts but you couldn't tell from the operation of the connected load. And a lot of the new equipment, electronics and such, is built with untinned stranded pigtails.
