Richard: yeah, I know that is the standard practice. I was musing on what the campground was attempting and how it could be beneficial. If all their 50 amp outlets were having both sides fed by a single to make available a total of 100 amps, albeit in phase with each other so no 240V, that would be a much larger cable than 6 gauge. If the cable was serving 10 sites the single line would need to be rated for 1000 amps, if conventionally wired it would only need to be rated for 500 amps , per line, and our 240V stuff would work. For the 1000 amp 3 wire setup, both power and neutral have to be sized for 1000 amps. In the 240V 4 wire setup, L1, L2, and neutral would each be rated for 500 amps. It just seemed to me that that the price of the wire might not be that different. But, that is just the engineer in me trying to understand what the heck they were accomplishing, I'm still clueless. That isn't new.
