Hi Joe…here we go…
I agree with every thing you said, expect.....it is not a requirement by NEC to use an anti-oxidation paste.
I agree it is best practise, and I always make sure the men use it when it is an aluminum connection. However it is not required unless the manufacturer specs call for it.
The code has several sections that talk about it, but none require it.
Article 110.11 Deterioration Agents
Article 110.14 Electrical Connection
Article 310.14 Aluminum Conductor Material
Article 250.120 (B) Equipment Grounding Conductor Installation,Aluminum and Copper-Clad Aluminum Conductors
I unfortunately had call Right Way Electric on the carpet for the very same thing on a project I was running. Right Way was the sub. I was red faced and embarrassed when I could not find any proof that it was required. They did say it was good practise but not a necessity. They also preferred not to use it in bugs because it would weep and cause the tape to come apart.
I couldn't argue.
If you find a section that requires it, let me know.
