Communication cable?

[The Iceman]

I have another question from my last exam I'm not 100% sure I answered correctly. To the best of knowledge the question asked which communication cable is universal? The answers were CMR, CMG, MP, MPP.
Looking over 800.179 (G), I answered Multipurpose Cable (MP). What I'm not sure about is could it be MPP?
I wish I could remember the exact wording of the question. I would appreciate any help you guys could give me on these types of communication cables.

My answer based on the NEC would be CMP. But I don't see that as an available choice on your test answers.

Given the choices you list I would say CMG because it is a general purpose communication cable

CMP may have been an answer on the exam. I'm looking for information on this subject that will help me if I come across this question in the future.

Look at 800.154(E) in the 2008. CMG is above CMR in the cable hierarchy. Therefore you could substitute a higher rated cable for a lower requirement.

The way the question is worded the only cable you could use in any application (universal) would be plenum rated. Lower than that would be riser rated (CMR.)

The wording of that question is poor to say the least.

I'm with Peter. I think the answer was supposed to be CMP.

I agree I was somehow thinking most common rather than one that can be used universally. Dooh

Edit: I meant CMR is above CMG in the cable hierarchy. Ooops.

We figured that out. :grin:

Thanks for the help. After reading your replies and 800.179 over and over and over.... I think I see were I made my mastake.

Just don't let Marc know that I made a mistake. I'll never hear the end of it.

I thought I made a mistake once... But I was wrong. :grin:
