john

I would just like more info on the listing

Now that you've brought it up, so would I.

Click this link then If you click on the link second from top you will see that a clamp that meets ul 467 will be fine ,.. I think this is the latest bulletin .

I don't think a gastite tech. bulletin changes the listing of a clamp that is listed for copper water tubing, who told them it is ok?

 

[JohnJ0906]

I agree, that looks like a regular ol' water pipe clamp. No info really given about the clamp.

 

[JohnJ0906]

What about non-copper water pipes? I see city water enter buildings with this pipe, and clamps are made for that. Are they listed?

I'm still curious about this. What about the clamps for bonding/grounding non-copper water pipes?

I seen, and used, ones that look like big u-bolts, with a connection for the GEC/bond wire. I just don't remember who made them. Are they listed for this?

Appleton has a clamp for both gas pipe and copper water pipe I guess I would use this one :smile:

Type GC​

Zinc​

Use:​

Ground clamps for bare copper conductor. For
insulated or bare conductor wire, copper AWG #2
through #8. Clamp is reversible.​

Note:​

GC-5 is listed for use with 1/2? through 1? trade size

our GC-5B because we provide plating of a material or

that sounds like a winner, I wonder how available they are, thanks for the info

 

[M. D.]

mpd , I have never seen a clamp solely listed for copper pipe. I'm not sure I even understand what the original concern was but I'm glad I helped ,.. if in fact I did.

 

[George Stolz]

M.D., where did you find that info?

 

[M. D.]

Why,... the world wide web ,...of course. I used to work on the supply side of the counter and I remembered a little zinc clamp , then I went and found it.

 

[M. D.]

George ,and anyone else interested , this link from allied has info that seems to fly in the face of using a zinc , or at least their zinc clamp , on a copper pipe, galvanic action , which is why I think the other company stresses the fact that thier's can be , may be, I don't know just a guess.
