sorry if I seem confused it's been sometime... ok that double lug for the grounding you said is suppose to be installed exactly where? On the casing?? I wish I could see a visual pic so I could get it straight in my head.
ok when you say "then out to your loads" are your referring to the neutral wire going out to the secondary load?.... There is no ground wire coming from the transformer because the ground is derived from the neutral at the first subpanel correct?
ok....well from the weatherhead we are connecting we are bringing down a ground to the disconnect. We lug the disconnect and land the ground there. That ground is suppose to go to building steel right?
After the ground leaves the transformer it hits a gutter. The ground is landed on the terminal block within the gutter which is connected with conduit to the individual fused disconnects , then from each fused disconnect to the structure's(it's a fire-rated steel storage unit) actual disconnect and finally the subpanel within the structure. The grounding should be straight forward.
Now when the neutral hits that gutter I'm a little hazy.... I'm guessing that we will have to put an isolated bar for the neutral to be landed in the gutter so that it can run STRAIGHT through each disconnect and on to the structure subpanel
And of course the hots will have to have some sort of isolated bar within that gutter so that each hot can branch out to each phase of the disconnects.
