I have an existing building and service, that is getting a steel framed addition added to it. I’m wondering if I need to bond the steel frame of the building out to the service disconnect, or if I’d be able to come off the sub feeders on the existing building. The service, grounding, and bonding are not done correctly at all. Basically the double throw at the pole was retrofitted with breaker so now instead of it being service equipment it’s a service disconnect, and now instead of the service disconnects being on the two panels in the existing building they are now considered sub panels and do not have 5 wires ran to them. All grounding and grounded conductors are bonded together in both panels. Would it be easier if I put another term box in place of where the double throw is and then I can have my service disconnect back at the panels inside the buildin. Set a ground bar and bond from of one of the services, and then begin to bond steel, water, ufer if it’s even present, or set two ground rods if not?
