Nothing prohibits a receptacle above the ceiling.

400.12 prohibits a flexible cord or cable above the ceiling.

Yup, receptacle permitted not the cord. Dumb IMO.

I thought the latest that Mike Holt's been preaching is that cords that are part of an appliance are under a different ANSI standard and were not subject to the provisions in the code not allowing flexible cords above drop ceilings?

I've never heard that do you have a reference?
 
Sorry I guess it was a UL listing thing, taken from a thread back in 2014. About cords and receptacles above drop ceiling.

Then there was a pretty lengthy discussion ("cords" above ceiling) about whether a power cord for a TV, projector, etc is in fact a flexible cord covered by the prohibitions in NEC 400.8. The arguement being that power cords are UL listed differently than flexible cords and thus not prohibited above suspended ceilings. After 105 thread responses, I'm not sure there was any resolution to the debate.

Clarifying this issue sure would go far into the discussion about whether or not you can plug a ceiling mounted projector to an above ceiling receptacle.

Does anyone have any further insight into this conundrum and whether or not there is any code activity to clarify the issue?



Mike Holts position is power supply cords have a different listing than portable cords and the power cords are allowed.​

New text ("flexible cord sets") was added to 400.12 in the 2017 NEC.

400.12 Uses Not Permitted. Unless specifically permitted in
400.10, flexible cables, flexible cord sets, and power supply
cords shall not be used for the following:

Yep, Mike created a stir over this. He was at odds with many over this and I think this is what led to the 2017 changes. I see in his 2020 Public Inputs he still has more to say on this.
 
2017 still makes my eyes wig wag like the lights on railroad track gates. I think the article still needs some refining.
