It would appear this installation is below code requirements - beginning with the lack of GFI equipment. The wire nutting of a bunch of neutrals together should also likely result in red tagging. However the correct installation and isolation of the neutral and grounding bus bars for subpanels is often missed by professional electricians. See:

Sounds like it's time for a rework by someone who is up to speed on the code.
