Section 514.7 cross references Section 511.7 for suitable wiring methods above classified locations for dispensing facilities. The wiring methods you listed are all acceptable assuming they are LFMC, LFNC or EMT respectively.
Excellent question. You're the AHJ representative. How would you interpret Section 511.7(A)(1) most consistently? Personally, wiring above the canopy, probably should be exempt. Then again, it doesn't clearly say so, does it?"on top of gas island can be interpreted different ways", but a question, please.
If the fixtures are mounted below the metal "roof" of the canopy but the supply wiring is above the "roof" would Art 514.7 apply to the wiring ?
