Guys, I am a homeowner. My profession is in electrohydraulics which includes low voltage (under 600V) power and control. This query is not work related. It is not homeowner or DIY, either. We are in South Carolina.
My wife is responsible for specifying roll-around projection and computer "things" for their new (public grades 5-8) school. I'll call the "thing" a cart. These will often have 3 to 6 cord-and-plug connected devices in simultaneous use, and an 100BaseT cable. The power and sources are a wall receptacles. The cart will typically be used from the room center,
I told her that my understanding is that the "power strip" either has to have its own 40 foot cord, or that the cart would have to include "permanent" (like plugmold or conduit connected surface mounted boxes) with an appropriate box with some strain relief. I do not think it is legal to connect the strip to an extension card. Her principal has listened to the purchasing department, and has decided to "mount" a strip, coil a drop cord on the side with the strip plugged in, and consider themselves in "high cotton".
Sometimes these will have 6 to 15 laptops on them, with their rechargers. In this case, there will be 2 to 4 power strips to plug into the "permanent" on-cart receptacles. I told her that I think this is a code violation. one power strip cannot be plugged into another, ie, cascaded.
Does the N#CEC address this abblicton? Thaks in advancd,Geeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
