If any thing I thought it was the other way around or no difference at all.
Wire does not carry voltage...??? :roll:If any thing I thought it was the other way around or no difference at all.
For NEC but doesn't stranded have more surface area and theoretically can carry more current? I have heard this but never thought much about it. I realize the insulation may be the limiting factor.Wire does not carry voltage...??? :roll:
Assuming you meant current, for practically all NEC applications, there is no difference.

The individual stranding does not increase the effective surface area at 60Hz.
At power line frequencies, including normal harmonics, we are concerned with the cross sectional area of the conductor. Skin effect and proximity effect are negligible below 266kcmil. I recall(?) the skin effect adjustment for 500kcmil is like 1.005, but regardless it is built into the NEC tables.
You guys are great-- thanks. I knew per NEC it made no difference but was curious if there was an actual difference. :thumbsup:

Im going to sound like a real idiot here but i thought everything in Ohms law was carried through the wire. I guess voltage is just a potential?
