It falls under:
(3) A listed electrical circuit protective system with a minimum 2-hour fire resistance rating. The
installation shall comply with any restrictions provided in the listing of the electrical circuit
protective system. Also the 6 feet falls under 110.3b manufacturer requirement.
Take a look here:http://www.datatechtx.com/pdf/lifeline/FPU-05.pdf
Thx

Is it me or could they have worded this better? A listed electrical circuit protective system doesn't sound much like 2 hour rated conductors installed in EMT. :)

I didn't see the 6' requirement in that pdf you posted.
 
Holy raceways Batman -
I found a drawing with "riser diagram" in the title. It's a fire system drawing. It's doesn't show a specific location, but does give the gerneral area location for each device. It lists the cable designations, number of conductors, size of conductors. Doesn't give any cable tray or conduit information, no interconnect or schematic information. Likely was used by the cable installers.

I'm surprised there was not a similar one for the instrumentation cables. Hummm ..... wait a minute ........ Nope. Out of 2500 electrical drawings there were just the two with "riser diagram" (none with just "riser") in title - both were similar fire system drawings.

Learned something new today -- All right:thumbsup:

Heck, if you were that anxious I could have sent you a PDF of a set I did for an assisted living facility. About 20 drawings, and after the cover page the next 5 were all riser diagrams!

Yes, I'm certian riser diagrams are useful in commercial building. I already got that - I promise, really. But I don't do any assisted living - no commercial at all actually.

However, they appear to be rare in heavy industry. Now I think I know why.

Out of all the ones bob listed, the fire system is the only one that had any. As Bob said, it gave an overview of the fire system.

Don't need any for power - the info is all on the one-line, equipment layout, cable schedule. As for the rest of the items on Bob's list - well, they are not normally installed systems.

Thanks for bearing with me
