Answer:
Adonis,
Chapter 3 of the NEC™️ provides general guidance on wiring methods. Each of the Chapter 3 wiring method Articles(320-398) includes a Section 3XX.10 for Uses Permitted, and a Section 3XX.12 for Uses Not Permitted. These Sections provide guidance on whether or not a specific wiring method can be used in a specific building, construction type, and/or environment.
