sir, I would like to ask if it is within code to install a electric extension cord to connect a ceiling mounted projector in a School. In other words the cord would lay on top of the drop ceiling and would connect to the nearest power receptacle to power the projector.

400.8(1), (2), and (5).

I'm bidding a similar situation with a drop down projector. The engineer plans state to put a receptacle above the grid.

Are there any alternatives? I know I could put a switch and hardwire it, but hardwiring a projector may be a project in itself.

I have been in this situation too and have had to hardwire them.

Just for clarification, I think there should be exceptions for these types of installations as well as above ceiling condensate pumps.

If de-energizing the projector is a concern?- most are shut down by remote today as it is! I have a hard time believing the school board inspector would allow such an install.
 
What I have recently seen is a 2x4 outlet box dropped down to be flush with a cutout in the suspended ceiling and a single outlet with a surface cover plate, painted to match the ceiling tile color. That single outlet is then wired back to a wall switch. What I don't know is how they suspended the 2x4 box. I assume on the end of a piece of conduit, but I have never been up in the ceiling to check it out.

When we do this we support a piece of strut (Kindorf, B-line, Superstrut, etc...) to hold the box solid and use a device and plate color to match the ceiling.

This doesn't help the drop down projector installation though.

What about using a longer IEC type cable and running it from the projector up through the drop ceiling over to the wall and back down through the drop ceiling and to an existing power receptacle. Finishing up with a piece of surface raceway designed for that application. It appears that the NEC wont allow terminating a flexible power cord above a drop ceiling, however says nothing about using the ceiling as a portion of the raceway being used to run the power cord back out of the ceiling and to a receptacle.
