I had a subpanel installed being fed from an existing 100a subpanel (they sit next to each other). I would like to confirm the electrician wired the ground correctly. He ran the ground from the existing subpanel's ground bar to the new subpanel's neutral bar. Also, does the aluminum wire require an anti-oxidant joint compound? The electrician told me he only uses it in a damp/wet environment.
