Hospital Transfer switch and Panels Em system under 150 KVA.
Critical System = Seperate panel, Seperate Conduits and wire.
No mixing with other systems.
Lifesafety system = Same
Equipment System = Same
At no time can theses three systems share and panels or raceways of the others.(expect as noted in 517-30 c (1)

Ernie, this is true.

There should be no problem in compliance if the job is planned.

The three Essential system branches are pretty much aligned with articles 700, 701, and 702 if you think about it.

The equipment system can share raceways, etc, with nonessential loads. Critical and life safety must be segretated, though.
