receptacle above ceiling

[david gum]

under what circumstances can you use receptacles above a drop ceiling

 

[roger]

For most anything, you just can't leave a flexible cord plugged into it.

[david gum]

there are rf filters that have low voltage power supplies that need to be plugged in above the ceiling

 

[roger]

If the power supplies plug directly into the receptacle there is no problem, if they have flexible cords on their supply side there is a problem.

If the low voltage items you are talking about have "wallwarts", plugin type transformers, with low voltage wiring from the plugin wallwart to the items, then that is permitted.

Cords are not permitted though.

Even further, I think the wall wart would need to have class 2 or 3 classification on its output for its cord to be covered by Section 725 instead of 400

I don't think I'll ever understand why cords used in this application isn't allowed.

I have not specifically looked this one up but there is several instances that must be acceptable as "Sensormatic" theft prevention CPU's are always allowed as are FAU's with a cord connection. The problem is when you have utilization equipment below the ceiling that might have the cord pass through the ceiling such as scenting systems, camera power supplies or television monitors which are certainly a hazard as they cannot be readily disconnected without entering the ceiling space.

I can't count the number of times that a customer wanted TV displays installed with cord and cable routed into a rec installed above the ceiling. Especially large retail outlets with national engineers drawing the illegal detail on their plans. They just don't understand when I tell them NO. http://forums.mikeholt.com/images/icons/icon12.gif
