End of Aisle Receptacles

[Marshmo]

Wired a farm/home supply type retail store a few months back. Now they are wanting receptacles on the end of seven of the aisles, for advertising TV screens and such.

I've noticed at places like Wal Mart and local grocery store that EMT is just ran straight down from the ceiling with no support. I've even seen MC used also.

This will be about a 20' drop from ceiling web truss to top of aisle. My question is what is a good way to do this and provide adequate support. I'm hoping to tap in to this knowledge base for some good ideas.

good way to do this and provide adequate support to tap in to this .

There ya go, answered yerself -- if concrete block wall, tapcons of course. Or even if poured concrete.

Legrand Wiremold TelePower poles are avilable in 15' lengths and work well for this

While a common practice in many retail facilities, that is only permitted for rigid or IMC where the conduit is connected using threaded couplings.

Thanks fellas, I'll probably go with the power poles.

RMC will cost less. Power poles do have a separate channel for communications cables though.

You can also use strut (available in 20' lengths) then attach EMT, MC, CAT 5, boxes, etc to it.
