Dnkldorf, that is exactly the situation I had in mind when I commented that the code needs to be changed. I fail to see how a foot or so of cord can make a significant addition to the fire load above the ceiling, or how those crumbly tiles can damage the cords.

I think that, on this issue, the code has passed "safe minimum" and attempted to mandate "perfect ideal."

And, lest anyone misunderstand my context, I say that the code precludes flex cord above the ceiling- and I think the code ought to be changed to allow some!
