When you say essential load, are you talking Healthcare and article 517? If so describe your situation in more detail, please.

What kind of load is this ATS serving? Is it an Article 700, 701, 702 or 517 load? Is the normal source an Article 230 utility service?

As long as the cable is an approved wiring method per chapter 3, then it is OK.

It's probably permissible, but I would argue that this would be an unwise design decision. Any event that might cause damage to the primary supply cable is likely to affect the emergency feed as well. For my two cents, I'd like to see both horizontal and vertical separation of these cables, in the neighborhood of 5 - 10 feet, if feasible.

Is this tray cable or armored cable?

My turn, does this matter? Either is an approved article 300 wiring method and should satisfy the wiring requirements of Article 700 shouldn't it?
