yes rodger raider answered correctly in post #2 but the real discussion is what can the outlet be used for..
It can be used for many things, use your imagination. You can't use it for a flexible cord prohibited in 400.8

The OP wanted to plug in a transformer for a CCTV now MD has to throw in this smoke hazard info..So my question is how would we tell if it qualifies to be above the suspended ceiling with UL203??
Simple, check the listing information.
If you are going to use a item in a plenum ceiling, it and everything associated with it will need to suitable for the installation, note what I said in post #69.
Now let me clarify my position, I think there should be some exceptions to the rules in 400.8 but there are not, so, if you try to use a cord above a ceiling an inspector should tag it or give you "special permission in writing" (good luck getting it)
You can install a receptacle in a ceiling for service use, but you can't leave a cord plugged in to it, you can also install a panel in a residential bath room but you can't put breakers in it, that's just the way it is.
