Receptacles on Cable Tray

Receptacles on Cable Tray

Receptacles on Cable Tray

(OP)
A client has several labs with duplex receptacles mounted on cable tray (all below the ceiling). Equipment on benches, tables or floor is plugged into the receptacles. They would like a similar approach for a new lab. I thought the installation of receptacles at this height for equipment mounted this low was against code (this would be a first time application for me). Am I wrong? Before I bring this up...would appreciate confirmation and applicable code citations.

I'm having trouble finding applicable codes...only citation I could find...
NEC 400-10 (pull at joints and terminals)


Thoughts/comments would be appreciated.


RE: Receptacles on Cable Tray

You don't specify exactly what's meant by "this height" and "this low"....  but the proposed installation sounds OK to me assuming the equipment cords are long enough to reach the receptacles without using extension cords.

RE: Receptacles on Cable Tray

If the receptacles are used for specific pieces of equipment, I don't see a big problem.  Might violate cable tray UL listing, but I don't really know about that.  Cable tray manuf. might have some insights.   

RE: Receptacles on Cable Tray

Are you sure duplex receptacles are mounted in cable trays?
Any chance they are using metal (or non-metallic) raceway?

Most raceway manufacturers have receptacles that mount in these raceways for the exact application you are describing.
