Re: Commercial Wiring
It depends on the construction type of the building or a particular part of a building. Wiring methods are permitted or excluded based on construction type, and not solely on the fact that it's a commercial use. All the wiring methods you mentioned are valid methods in commercial type structures, but it all depends on construction type. Annex E of the NEC goes into this a little. Learn a little more in 334.12
