As a raceway, probably not. As a space to run a cable, FMC or LFMC in then yes excluding the plenums in it.

I don't really see a rooftop a/c unit in article 300 as an acceptable raceway. I've done as you suggest, but I run MC cable inside the RTU (poked up from within the confines of the curb kit) and not conductors without a raceway.

I have my doughts about it being legal too.As to any danger in doing it i dont see it as a problem as other wires for the unit are already in it.

What doubts?
Cables and raceways OK, open condutors not OK

This is not my project,i pointed it out to our leader and thats as far as i go.The fix would not be hard.This outlet is the required one for service.

I really wish more of the HVAC guys would start ordering their RTU's with the factory disconnect and receptacle. In a world of competitive bidding, this isn't really happening unless the contractor is bidding on the whole MEP package.

Exactly,life would be easy and units would look better too but they want to offer low price and GC just don't see the differance.The EC can't count on it so he assumes he will provide.The 25 foot rule needs changed too as it drives cost up.
