So, in this subpanel, the big aluminum neutral wire entering the panel is not insulated. This is an existing home, but the service was upgraded to a 200 amp service and the subpanel is brand new.
I’m not an electrical inspector (yet), this is a panel I saw on YouTube.
2018 IRC E3406.5 “... Except where otherwise permitted in Sections E3605.1...current carrying conductors shall be insulated.
2018 IRC E3605.1, #2 says that “An aluminum or copper-clad aluminum grounded conductor shall not be required to be insulated where part of a cable...”
Is that neutral part of a cable? Or is it an individual current carrying conductor
