Can anybody lead me in the right direction for any requirements by Cisca/ ASCE/ because agency has any requirements for seismic ceiling grids wires to be color coded per trade?

Good question "Olllie".
So your saying the ceiling wires are all one color, the suspended electrical is another color? the suspended data another? plumbing is another color and so on ?
Where is this requirement coming from. I gotta see this in practice

I did find something in the NEC 300.11 B (1) and (2) but not for every trade

I am curious because I have never seen colored hanger wires, so I looked for information on 300.11 B and found this article http://www.electricallicenserenewal...cation-Courses/NEC-Content.php?sectionID=56.0
Has the section changed since the 2014 NEC. The code sections requires identifying raceways that support other raceways. I don't see anything about identifying hangers.

I'm not sure about wires but suspension cables are to be color coded per ASCE 19.
Something to do with readily identifying the cable size during installation & inspection

300.11(2) in the (CA Electrical Code), has the same language for non-fire rated assemblies.
