Flatscreen Televisions and Drop Ceilings

[jar546]

You walk into a conference room of a recent renovation for a final electrical inspection and see a new flatscreen TV mounted on the wall. You then see the power cord for the TV running up the wall and through the drop ceiling. Above the ceiling is a receptacle that the TV is plugged into.

Is that a legal installation per the NEC?

We can start the debate when you find a section then.

Take a look at UL 817 and UL 62

Chapter 4 does not cover power supply cords for equipment

I disagree, the scope of 400 covers flexible cords and cables. If a listed cord set is constructed of a flexible cord of the type listed in 400.4 then the installation of that cord set in a building falls under Article 400.

422.16 applies to appliance power cords specifically waste disposers, dishwashers, trash compactors, range hoods, ranges and counter mounted cooking units.

Ceiling-mounted projectors almost always violate this. I hate to think how many times I've had to be a bad guy and tell the dean that they messed up on the newly remodeled classroom he's showing off.

Put the receptacle in the ceiling and they are good to go.....
