Building Wiring Installed In Manufactured Structure as Race

[tryinghard]

We have manufactured structured building with box metal columns, beams, & joists that the client is hopeful to fish all wiring in (no exposed conduit). Cabling is certainly an option but what about building wiring? In light of 300 & 310 with raceway definition I wonder if the manufacture can state their system as raceway approved? I wonder how light standards handle this? Left alone I?d say no building wiring but I sure want to use it for home runs to receptacle outlets on the columns, any wisdom out there?

I don't see how you can install wires in it if it is not a raceway or conduit of some sort.

Can you run NM in this type of structure?

Yep but if the underground home runs are cable the conduits quite different as opposed to using building wire. The cabling would be tray type rated for water (UG)
