Main panel hot wires using neutral busbar at a different panel ??

[Mike Lamb]

I'm trying  to get my head wrapped around this. A neutral wire has been tapped at the bus bar of the main electric panel and then run to another panel with a bunch of hot wires which are wire nutted at the separate panel and those wires are using the neutral bus on the separate panel instead of the main panel. Is this okay? If not, ramifications?

The first picture is the neutral running from the service panel. the next two pictures are at the auxiliary panel.

Are you trying to say that the individual neutrals for a number of circuits, running from the main panel to an 'auxiliary' panel, are replaced by a single large neutral?

Yes.

This is the other panel - I don't know if subpanel is the right word. The 100A main has no wires running to it.

The neutral must accompany each circuit. It's because separating them results in stray magnetic fields that can heat conductive materials in the vicinity. Besides that, the codes offer no formula for calculating the size of common neutrals that serve several branch circuits.

Thanks.

Is this a transfer panel?

Do you mean to a generator? No.
