Will standard PVC sch 40, will be an acceptable wiring method in an above the ground metro station, I think it is not acceptable, but I need specific literature to support my point. Can anybody help me?
 
If it qualifies as a place of assembly covered by NEC Article 518, the permitted wiring methods are:
518.4(A) General.
The wiring method shall qualify as an equipment grounding conductor in accordance with 250.118 or shall contain an equipment grounding conductor sized in accordance with Table 250.122, and shall be any of the following:
  • (1) Metal raceways
  • (2) Flexible metal raceways
  • (3) Nonmetallic raceways encased in not less than 50 mm (2 in.) of concrete
  • (4) Type MI, Type MC, or Type AC cable
