The clamp is listed for use for a GEC with or without armor. I question whether it is listed for AL. The packaging should indicate if it approved for use with AL.That pipe clamp is for use with armored copper ground wire.
You should get a clamp made of zinc die-cast metal which could be used for either copper or aluminum wire. Here is one from Arlington, cat #720Z:
No-Ox is not needed. The small saddle clamp is used for bonding the metallic armor of the GEC if present which in your case is not. I'm still questioning the screw you used to mount the lug to the panel. It it a self tapper?When looking at them they all said either for copper only .. or... for Al only (didnt have "FOR BOTH" )and i have a big copper pipe..didnt see one for both in a main electric supply store-only online.
I have applied the NOALOX to the aluminum.Before contact w copper.
Id rather it be inserted at the smaller area with the smaller clamp-on it seperate- than have to use a larger amount of it on the AL clamp when its in contact with the large copper pipe.
Yes. And the screw is fine.so the zinc clamp will do fine with copper? that one i had was brass
This clamp appears to only be listed for copper conductors. It is not listed for AL conductors. What is on the packaging for the clamp in the earlier photo?Ok thanks...Here is what the zinc one i have says on it

It has nothing to do with material the clamp is made of. It depends on what the clamp is listed for. Somewhere on the clamp it should indicate what it is listed for. Such as AL only, or CU only or AL CU. check the clamp for what it is listed for. Happy Thanksgiving!!hidden1 said:Brass for copper connections..(no AL)
Odd that a local electricians supplier wouldnt have it if it were NEC required..
So many older homes still use/need these..
Yes. Good to go.hidden1 said:This is crazy but the exact same clamp i have(yes same item# too) on earlier pic that you say wont work on AL-online says Al on it..
I take it i CAN use this after all?
