I have a client that wants to park an RV on the other side
of a Storage facility driveway. He wants the 50 amp RV circuit to run surface across the driveway from the building with available power and he wants to use a cable ramp. Never been asked this one before and he wants the price right away. I'm wondering if a UL listed ramp is available to protect rigid conduit. RV's will be driving over it frequently.Anyone familiar with an approved ramp or have any suggestions besides going underground or overhead?

IMC is better than RMC...
Such protection is pretty effective for temp power at construction sites.
In such usage our idea of a cable ramp is 2x6 lumber....
Grainger might have something suitable.

The company in the link below makes a protector ramp suitable for that purpose, but I don't think it would be required to be UL listed, since it is not an actual fitting or part of the RMC wiring method. I wasn't able to locate anything in the White Book pertaining to protector ramps. Handiramp

Haha! Yeah I'm familiar with the 2x4 method. Heck I've seen
cords running across heavily traveled roads without
protection. Thanks for the responses. I think I'm going to
propose just installing an outlet and let him worry about protecting it across the road. Less liability to worry about.

Last I looked, Grainger had ramps made by Hubbell for cord protection, & suitable for traffic crossing. Hold your wallet....they were in the $400 range I think.

Looking at NEC 400.7 and 400.8 and wondering whether a
cord laid out for a weekend or two a month across the drive and protected by a ramp would sneak in under the provisions listed. An RV is portable right? Opinions?

I don't see a problem ... nor do I see a problem with any means used to help protect the cord.
Indeed, some time back I posted pics of such a cord thaqt was run through a garden hose. In that instance, the cord went across a parking lot for a 'sale' event.
The world generally has no problems with honest applications; it's when that RV sits in place for a decade and is rented out as an apartment that code officials start getting grumpy.
