Cable tray passing through Battery Room

[NickParker]

What is the type of cable tray to be used, when it is passing through Battery Room? Does NEC specify the type of cable tray/conduit to be used in battery room?

In my opinion, a cable tray made of material as per art.480 and installed as per art. 392 is permitted to be installed in a battery room. However, the cable running in cable tray has to be permitted also to be installed in battery room. For instance, according to Art.334.12:
(A)Types NM, NMC, and NMS. Types NM, NMC, and NMS cables shall not be permitted as follows:
(7) In storage battery rooms
