I work as a consultant to a national quick-serve restaurant chain. They wish to upgrade their menuboards and have proposed that the boards be plug-and-cord connected to quad outlets within a wall mounted truss structure.
The proposed arrangement they provided shows a whip from the branch circuit into this structure to a quad outlet receptacle. Then several menuboards would plug into this outlet receptacle. This all seems to be reasonable until they then show the next quad outlet receptacle with a cord and plug that plugs into the first quad.
There are a total of six quad outlet receptacles for the menuboards and each quad outlet receptacle is fed from the previous one via a cord and plug. I have looked thru the Code and cannot find anything specific related to this wiring method, but it just does not seem Code compliant. Almost seems like using made-up extension cords for a permanent branch wiring system.
Is this an acceptable wiring method? If not, can anyone direct be to the Code reference(s)?
