Telephone grounding

[serkel49]

Is there anybody from Qwest out there?
Well this Qwest inspector would not allow the groundwire I stubbed out(4ft) to be acceptable for grounding his system fo this new house. What I did is to run a #4 bare copper from the panel in the garage looped it at the UFFER and stick out the rest through the outside wall. I've been doing this for a while and none of the (real) inspectors fail me!
This Qwest Dude did not want any stranded wire to ground "his system" he demanded some solid bare wire #6 (I think)needless to say, I looked it up in article 800, and there's no mention about using solid vs. stranded. Can anyboby clairfy these allegations?

Does anybody know the origines of Uffer?

Re: Telephone grounding

You're not going to find anything in the code for what the phone company wants for a ground. You will find it in Qwest's general procedures and practices. I just did a couple of upgrades for Qwest in Seattle and they too wanted a #6 ground. However, they didn't care where I got the ground from and recommended that I just hit the nearest counduit with a bond clamp, then run the wire over to the phone board.

Probably because stranded #4 is not something an installer is going to easily connect to a residential demarc/protector and make it look nice.

#10 solid is right for this, it should be good for up to 6 pair. More than that you use #6 solid. Bug it onto your #4 in the garage.

One Web site you might try to confirm is http://www.qwest.com/techpub/ about 1/2 way down is a document 77350 which is Qwest Equipment equipment Installation guidelines it's a little thinner then the NEC but not much, then a little farther down is 77355 which deals with "Grounding Central Office and Remote Equipment Enviroment" but it is considerably thicker,

It's named after Herbert Ufer, the fellow who realized that concrete encased rebar made an excellent, low resistance grounding electrode.

According to the story I heard, he was a president of UL and did the research on behalf of the US Army.
