I realize this is drifting OT but I had a situation several years ago where
an isolation transformer was used at a remote building. In that case, I
believe the NEC addresses the distribution as a separately derived system
and as an exception to the general rule, neutral would bond with ground in
the remote building's panel. I don't recall is ground must be pulled from
the main building in such a system if there's no direct conductor path
across the transformer.
