Saw a home today and the service panel was at the meter on a pole. 200 Amp panel, 2/0 CU The two conductors out the bottom into smaller conduit fed the outbuildings.
The 200 Amp main breaker went to the house.
In the house, another 200 Amp panel, 3 wire feed, neutrals (grounded) and grounding mixed under the same terminal screw, and bonded.
The two panels are 50+ feet apart and were not connected by fence, etc.
To my tired train of thought,
- the interior panel needs a separate bus bar for grounding conductors
- remove bonding strap
