There is a lot going on in this panel, but I had 3 topics I could use some help with.
This panel appears to have an unsecured 70A backfed breaker at the top left. The diagram was attached to the left side of the cabinet interior and is blocked by lots of wires.
Does this breaker feed the entire panel or only the upper portion? The drop from a 200A service, to a 150A panel, to a 70A backfed main seems has me questioning this configuration.
When I’ve seen these in the past the opposite position is usually open to prevent overloading the stab. In this case, there is a 50A breaker for the range in that location.
Does anyone know the amp limit on the stab for this panel?
I didn’t locate a bonding screw for the panel, but this open hole on the center of the neutral and ground bars seems like it may be missing.
