Does anyone know if there is a code violation in regards to allocating conditioned (from UPS) and non-conditioned (from utility) power lines in the same metal conduit? Conditioned power is used to feed some laboratory equipment. Utility power is used for the lighting system.

Thanks!

No, but it would be silly since the UPS isolates you from power surges that you would re-introduce to some degree with running dirty power parallel in the same conduit.

Code issues aside, I'd be concerned about the posibility of getting the neutrals mis-connected. Besides, some building UPS systems could be looked at as seperately derived sources.

If by utility lines you mean - service conductors, 230.7.
