I know it isagainst the NEC rules, but if you parallel two # 6 copper wires, would that be sufeficient for a 150 Amp Svc.. i.e., put two togather, for one 120 v leg, two more for the other 120V leg, for the 240V supply, plus the ground, about 100 ft from meter to fuse box.? No worry about law suits here, I am in Hondurs,

Well if no holds barred, then #6 copper wire, at the 90 Deg C rating, will carry 75 amps.

Then, considering as you say, no holds barred, and some future rule gets created and enforced, which is very doubtful, then 2 # 6 paralled, would create one leg of the 240, and same for the other, ground properly, and that would work for a 150 Svc panel?

Don't forget, I am in Honduras.. only rule is, if you are brave enough, do it.

Someone talked this town into replacing all their transformers, with much larger ones, I mean hundreds of them, lithts were off and on for days, then, they flipped the switch, at least 5 or 6 exploded immediately, and at various places, one here, and one there. Continues to go . I actually saw 2 of them go.. while driving past.. sounded like a 500 lb bomb..

Also, I forgot.. I have a Square D 150 amp main to install, will drive a 8 or more ft gnd rod directly below the panel. And it came with a separate connector for all the green grounds, should this ground bar also be tied back to the neutral at this point, or leave it separate, and the system is double groounded.. Back in the early Satellite days, we had trouble with grounding systems in some houses.. I think they called it,, different ground potential, which caused some receivers to get upset..

The neutral, equipment ground, and the ground rod all connect at the location of the main breaker. From that point on, the neutral and equipment ground are separate.

Honduras Bob-

I spent Xmas & New Years in Costa Rica (Pacific side) & saw some pretty "inventive" wiring jobs but in the two weeks we were there nobody got zapped.

The only major concern I would have about your installation is that someone in the future might remove one of those #6's & thus reducing your ampacity by 50%. Anyway to make it more tamper proof?
Cheers
