sign cords can not be plugged in above drop ceilings, SJ cord is considered a cord

Art. 400.8(5) will not allow a cord above a ceiling. The receptacle is fine but not a cord. Use a direct wired units.

personally . I think it's a bunch of crap ! I'd bet my life that a piece of cord lasts longer in a fire than A piece of NM cable ! A heavy duty cord has better insulation properties and overall strength than NM any day . As dumb as I think this is , put the receptacle in the ceiling , or high up on the wall , to avoid problems .

what if the transformer is above the ceiling tiles and sign below... The cord or whatever wire that usually feeds neon sign, can that run through the ceiling tile.??.. I haven't done any before so excuse my ignorance.. I had to install receptacles above a drop ceiling which is feeding transformer which is also above the drop ceiling...no neon sign at the moment...

The reason is because of fire especially if the ceiling is a plenum. Also if it is above the ceiling then no one is likely to see if the cord gets damaged or frayed.

They need to use a trany that is direct wired.

It has been covered many times in this and other forums, but bears repeating here....

As Dennis said in post #4, there is NOTHING in the Code that prohibits installation of a receptacle above a drop (grid, suspended, pick your favorite term) ceiling.

However, good luck finding anything allowed by Code to be plugged into it. :laughing:

My take is install the receptacle and walk away. What the building owner plugs into it is not of your concern..as long as you didn't plug it in for them. :thumbsup:

so if that portion is direct wired to transformer and the transformer and receptacle is above ceiling , I'm ok then.?

. I understand the reason Dennis , but still don't agree with it , lol ! Let's burn a piece of NM and I piece of cord side by side and do a toxicity test . It's just another area , I think the NEC is way off . You know as well as I do , that some of the stuff ( flying splices , buried splices ) have been gone until only discovered and corrected . A receptacle directly above a sign with a cord from the sign that plugs Into it , will be fine forever . Especially if it's on an afci breaker , which is pretty much the case anyway ?

I don't think commercial buildings require arc faults...

they don't . When did this being a commercial building come into the equation ? It could have easily been a guys mancave and neon beer sign ? Either way , as dumb as I think it is , keep the " dangerous " cord out of the ceiling and you'll be fine . If you don't , you'll be fine too , but not code compliant .

how about a video projector? would be allowed or it falls under the same category?
. It's all a bunch of crap ! A listed cord assembly from a factory piece of equipment does not qualify as an extension cord ! I've plugged in numerous condensate pumps ( above suspended ceilings ) that had vectors cords attached . How do you address that ? Poke the cord through the ceiling tile and plug it in under the ceiling , lol ?

what about a plenum ceiling filled with PVC , or ABS plumbing Pipe ? I've seen that more times than I can count , but a factory cord is a big problem ?

From my experience, Ive never seen a PVC pipe fall apart.

Ive seen cords fall apart when I grab them.

The insulation becomes brittle after awhile.

Geographically challenged but if NJ follows the IMC the PVC and or ABS piping isn't permitted in a plenum ceiling.

I'm with you. Everyone does it. No one ever got hurt.

I see PVC in the ceiling all the time.

I guess I don't pay attention to the return.

Plenum ceiling no, non plenum you can?
