ECN Forum Forums General Topics of the Trade General Discussion Area 350 mcm for 300 amps?

I think GJ's right.
The benefit is to you. You won't have to buy 350 over and above the price of the 300, pull out the 300, and do the job over with the 350

I don't know what you'd want to do with the 720' of 300kcm that had been pulled out, but I wouldn't want it sitting around the shop here.
