Face down mounted receptacle - is there is weight rating?

This question comes from a discussion I had with other inspectors.
Stated installation example: In a supermarket there is a ceiling mounted receptacle outlet in the acoustical tile ceiling which is used for seasonal refrigerated cases/coolers which are moved into place when desired. The connection is via a cord and plug to the receptacle outlet 14 feet above the floor.
There is no strain relief supporting the weight of the cord, the receptacle is supporting the weight of 14 feet that 20 foot long (cord length not measured, length is estimated based on ceiling height and cord laying on floor at cooler box) with the cord being 10-3 with ground SO cord.
Stated question is: *IS* a strain relief required to support the weight of that cord?
After looking through the 2008 NEC and the 2008 UL White Book and not finding anything allowing or limiting the weight on the receptacles, I sent an inquiry to UL for information and possibly an answer.
I will post that response when I receive it.
