Hey I have a question. I really should know this, but I'm going to ask anyway. Why is automotive cable, automotive cable? I notice a lot more smaller strands than in wire of comparable size, in say commercial applications. Bigger wire is always better, in my opinion, and I was going to run something crazy, being I'm about to build another Wal-Mart here shortly. I was thinking about running 350 MCM, or maybe just some 1-0. Would I have a problem with that, being the wire is bigger, but I don't have 2 million strands. I'd have to get my ugly's book out to tell ya how many. But my theoritecial mind tells me to remember what I know about wire.
Electrical current runs alone the outside of the wire, not down the center. So having smaller strands would increase the surface area of the copper, and therefore allow the larger current to pass with less resistance.
But being smaller, I would think it would heat faster. Is it simply to hold the larger 'instant load', from starting, and not necessarly to hold it for a long peroid of time? Maybe this is why cables corrode inside? They really arent big enough, and are the 'cheapest route' dealers decide on... cost/people biotchin. ??
