I have a 480 volt 4 wire Y Gnd. service to a main disconnect in which it is bonded at that point. It is then brought into a 3 pole transfer switch the neutral conductor is not brought to the transfer switch but there is a EGC connected. From my generator there are 3 ungrounded conductors and a ECG landed in the transfers switch as well. There has been no bonding of the neutral bus and ground bus in the generator . The way I see it this is defined as a separately derived system and there is not an effective ground fault current path on the generator supplied system. I need to install a bonding jumper in the generator and add GEC to correct this installation . Am I missing Something?
