    Good Morning, We have an Assisted Living Facility that is fed from a Utility transformer and a Generator back-up. We have the service Equipment  fed through a 4 pole ATS from both sources of power. The MDP (Service Equip.) has a Main Bonding jumper and the Generator has a System Bonding Jumper because the neutrals are being switched at the 4 pole ATS. Question is at the second service for the Fire Pump is fed from the Utility transformer and Generator via the Fire Pump’s 3 Pole ATS where the neutrals are Landed on a common bus. It seems to me, like it really should be a 4 pole ATS in the F.P. Controller otherwise how do I determine whether the Generator is a separately Derived system or not?

    Thanks, Kelly Wofford
