As I was scrubbing some no-ox into a AL feeder today, I recalled being told a few weeks ago that it was no longer necessary.

Is this something new?

Sounds like shirt pocket electrical code theory to me...:laughing:

It very likely may be. I heard it from J. Random Wirebender (meaning, I forget who).

I was hoping maybe that all the AL made in the last few years was some new alloy and nobody told me. :blink:

I think the aluminum has improved and a most lugs etc. should be dual rated. I still use it anyway.

The new aluminum alloys corrode just as bad as the old ones did

Fellas, here is the relevant text from that Southwire PDF Cow linked.

Terminating aluminum conductors

1. Always use a connector that is listed for use with aluminum wire.
2. The following is recommended but not required. Always follow the connector manufacturer's instructions.
   • The surface of the conductor should be wire-brushed to break any aluminum oxide barrier leaving a clean surface for the connection.
   • The use of anti-oxidant compound, joint compound, is not required unless the connectors manufacturer requires it. However, the use of a listed joint compound is always a good practice.
3. Always tighten set-screw type connectors to the manufacturer's recommended torque.
4. Most importantly, do not re-torque the terminations as part of routine maintenance. As with copper conductors, repeated tightening of any set-screw connections can result in the eventual “biting” through the conductor causing the termination to fail.

I have skimmed that document many times but never noticed the page on terminating their AL.

Quoting from pg 24:

"The use of anti-oxidant compound, joint compound, is not required unless the connector’s manufacturer requires it. However, the use of a listed joint compound is always a good practice."


Edited to add: We all seem to have found page 24. :laughing:

I will just keep doing what I have have been doing - scrubbing it in with a wire brush.

It has been a long and painful day. I am so far behind on jobs that I really need to work tomorrow also to try to catch up a bit. A bunch of outdoors stuff and the high temp is supposed to be 29.

So, I am going to go to bed and consider my poor life choices while I drift off to sleep. Good night y'all. :thumbsup:

Yes.

There is a new public poll where you can choose more than one answer!

We use it,The inspectors like to see it, They are happy.

Also they like to see galv paint on threads we make on rigid.

Also they like to see galv paint on threads we make on rigid.

Do you use something to get the cutting oil off the threads (like maybe acetone)? I would think just wiping the oil off would leave enough of the film that the galv paint won't stick in the long run. It takes a lot of diligence to do that paint thing correct.

I wonder if no lox is trans dermal?

I had this conversation with a sales guy at a show. He says I bet you are still using that stuff. I said show me where it says in any of your literature not to. He spoke with one of his engineers and they pulled out a similar document saying the same thing as above. Unless it says not to, I'm still using the secret sauce.

I wonder how much of that secret sauce i've ingested....? ~CS~

Probably somewhere along the lines of asbestos you've ingested working construction in older buildings and homes.

Or insulation i've inhaled Pete

on the bright side, i won't burn, rust or get cold as easy.....~CS~
