AL in Panel

Recommended Posts

Right, shouldn't have more than one conductor per terminal, but that's not the big fish in the photos. The big fish is the aluminum conductors. There was discussion in this forum on that topic recently. Check it out Anatol.

Here is a document I use in my reports sometimes. It helps explain the doubled neutrals part of the issue. The doc is hosted at my server and it will always be there in case you ever want to insert the link into a report.

It's curious that Jim Pauley doesn't mention 110.14(A) in that blurb. It contains language that requires terminals for more than one conductor to be so identified. It and its forebears have been in the NEC for decades. In my opinion, it's a much stronger argument than 110.3(B).
