A 600 240 volt 3phase service disconnect feeds a wireway that supplies several feeder disconnects.
One of the feeders supplies a wireway, with the conduit acting as EGC.
The wireway supplies 4 disconnects that feed 4 breaker panels via SER cable.
In each disconnect, the grounding conductor and neutral from the SER are connected together to the neutral lug, which is floating (not bonded).
All passed inspection.
