Hello Guys,

I am working in a commercial building, 200A 120Y/208V service. The meter is on the building, with the service conductors terminating in a 200A MB panel. Their is a 200A sub in the next stud pocket over fed from the main panel.

Here is the controversy. I asked for 5 runs of THHN to feed the subpanel, and the boss told me that it only needed 4 wires.
I asked him how you could make a load side connection to the grounded conductor, and he responded the inspector told him that because the panels where next to each other, the neutral and ground where bonded in the subpanel as well as in the main panel. Could anyone play devils advocate for me and tell me where I have gone astray?
Thanks, Gary
