I just wanted to double-check with you on this set-up. This has four panels with the last one ending at a detached garage which was about 75 feet from the house. The set-up went as follows:
Service panel (1) on far side of house > to distribution panel (2) in basement > to disconnect panel (3) on the other side of the house > to the detached garage panel (4).
Does the disconnect box (3) need grounding or bonding? They just used a connector to join the service from the distribution panel to the service going to the garage. And should the detached garage then have it’s own grounding/bonding? Thanks.
