I have received mixed answers when consulting with my electrician, and wanted to seek answers from a more educated source.
Upgrading service to my new home.
New meter head, new main breaker outside.
<I think this is whats throwing confusion> The disconnect I selected has 2 sets of breakers (technically 4 breakers mechanically joined by 1 bar) 2 breakers serve as the disconnect from utility to breaker panel inside. The second pair of breakers act as a min disconnect to an 'internal' sub panel. There are spaces for 4 branch circuits to be fed directly from this panel. From the disconnect, I have 4 conductors S.E.R. type cable run inside to the new main panel.
I have (2) 8ft ground rods connected to the ground/neutral bus at the disconnect outside.
Inside the house, the main lug panel has a ground bus ( with no large lugs, just bonded to chassis ) and neutral bus down each side of the panel. The neutral bus on one side has a lug slightly larger than the other, and both buses are bonded.
Two questions :
1. Assuming I terminate the neutral to the inside panel using the larger lug, there are no remaining lugs large enough to hold the bare 4th conductor / ground. How should I properly terminate the ground conductor ? ( should I just add a lug of appropriate size to the chassis ? )
2. What ( if anything ) should be bonded. One electrician claimed this was a sub panel fed from the 'main' outside and nothing should be bonded, another said it wasn't a sub, and due to use of S.E.R. , if all 4 conductors were used, could bond neutral to ground.
I just want to make sure I'm following code & being safe.
