I see there are multiple threads about this issue but I am not seeing my questions answered in any of them. My local gas companey is requesting bids to bond around 100 gas systems in trailers in my town. They are using a Pro-flex system and requiring that a bonding clamp is connected to the brass fighting they have installed(I imagine this is the isolation fitting I am hearing about). From there they are requiring a bonding wire the size of the full amperage available through the electrical service(all 100 amp services so #4 copper I assume they mean). But they do not say if the wire needs to go to the panel or if it can bypass the panel and I can split bolt it directly to the main cround coming out of the panel to the ground. In this case since it they are all trailers it would be easier to go directly to the ground wire because the pipe and wire are both under trailer. I contacted them and they said they are leaving it up to the contractors. I want to know if there is any reason I can not just bypass the panel and go straight to wire directly over rod. And also does anyone know the clamp size I will be needing to connect to the pro-flex brass fighting?
P.S. Sorry for huge messy paragraph I'm in a bit of a hurry.
