Thank you, I should have looked at Annex E for this information instead.
I imagine that the building designer or architect would have to provide the necessary information for the plan reviewer.
reno, when was the last time you inspected or installed wiring systems or equipment in the space identified by this thread concerning the question I asked.
I think that many of the spaces above the ceilings in many buildings is woefully in violation of Article 300 and Chapter 7 and 8.
Ain't that right, JC, JS, JS, and ME, etc.?
I have some pictures somewhere from back in 1981-85 from where I worked once!
I think a field trip and inspection to any office occupancy would find some surprises.
