I am normally a romex jockey. I am now bidding a metal detached building. It is a red iron framed building with no metal studs for sheetrock.

The customer wants a minimal install, cheap as possible. I would like to do the whole thing in mc cable, but see where mc cable can not be used where subject to physical damage.

I plan to run EMT up to the required height, install a junction box, then run mc cable to the lights. He just wants one plug near the panel box, so that will be easy and cheap enough on the plug.

Question: Where is the height requirement found for "not subject to physical damage", and any disagreement on the installation method mentioned above or suggestions would be appreciated. romex jockey language please.

I aspire to be fully commercial capable.
 
Subject to physical damage is very subjective. Just because it is exposed does not, IMO, mean subject to damage.
 
Subject to physical damage is not defined by the NEC so you would need to ask the inspector or AHJ what their interpretation of that term is. If it were me I would use all conduit.
 
I'm with Rob. As little as you are doing inside, I'd just pipe it.
Besides, your conduit will provide a good "support" for the Romex or Cord that he will throw in a week after you and the inspector are gone. :)

Even if you went up the typical 8' with emt by the time you switch over to mc, @@ figure out the extra support costs IMO just run the emt. Looks better also, unless you are gong to.buy your first bender with the profit on this job.
