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.
