OK Guys,
I can see your concerns,
But, at what stage does common-sense come into the equation?.
These cables are on the outside wall of a building, could someone tell me why they need to be de-rated, considering that they are in "Free-Air"?.
I think that sure there should have been a bit more cable tray installed for the stuff that was installed later on, possibly under the original tray.
Don't get me wrong, I'm not saying that this sort of thing is OK, it's not!.
One other thing, painters need to be shot for covering cables and thier supports with paint, ever taken a cable off of a wall and found the thing painted over multiple times and have the saddle screws tear a big patch of paint off the wall?.
