guys, I need help with this ons... given a large multifamliy dwelling unit has (2) services, The building has a (2)hour rated party wall halfway the building, this is not a true fire wall, therefore this is considered to be one building. my question is to comply with 250.58, to have a single grounding system, Can the bonding jumper that connects service #1 to service #2 be routed through the attic of the the building ? thanks, mj
thanks Roger, I have a contractor that do not understand the purpose of 250.58 since the slap in already in, I was going to suggest routing the bonding jumper through the attic to create a single grounding electrode system.
