Plenty of light commercial is wired in T and E round here, and it seems to do no harm. Often in basket trays in the ceiling. It can be done well, and makes certain other things easier, but it can also be an excuse for thrown-in spaghetti hoops of the worst kind.

It was never forbidden, but it is not really a good choice for exposed wiring in a heavy industrial setting where SWA or conduit is a better choice, and less likely to go badly wrong when it meets a forklift.

Some organizations have ‘house rules’ that dictate what types of wiring are to be used where, and there may be insurance agreements, but not the wiring regs per-se.
