Nice looking work but ...

The pancake box issue observed by others.

In the first picture to the left it appears that 2 cables go through each hole. Elsewhere it appears there is only 1 cable through each hole.

The staples appear to be spaced at 16".

So many wires, so few subpanels?

Issues like those brings up questions about the competence of the worker that can only be resolved by being on site.
