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.
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.
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..
