Russel's thread about schedule 80 PVC got me thinking about this.

UL and the NEC consider schedule 80 PVC in the same class as RMC as far as damage resistance?

UL says
Quote
The marking ‘‘Schedule 80 PVC’’ identifies conduit suitable for use where exposed to physical damage and for installation on poles in accordance with the NEC.

I can not imagine running a PVC up a street pole. Beside the fact that our local POCO would not accept it, all it will take is one small bump from a car to break any PVC.

Is running PVC exposed to physical damage common in other areas?

Could I come up out of a slab with schedule 80 PVC at a loading dock and satisfy the NEC?

Sometimes I wish we could get schedule 120 RMC for some locations. [Linked Image]
