Two sets of SEC?

Pushmatic panel as an RDP in the garage with finished walls. It looks like there are 2 sets of SEC, one going to the main breaker and a set going to the side lugs. I have not seen this configuration in a panel before, unless it is a type of split bus.

Are you certain that those are service entrance conductors?

The label inside the panel will provide a depiction of the buss arrangements, bond screw locations and other important information.

It sure looks like 2 sets. I see 2 neutrals, 2 hots going to the main breaker and 2 hots going to the side lugs. Since I can’t see anything in the walls I am not sure exactly where the SEC go or are coming from.

I did refer the client to an electrician, fortunatly for him he says he has a few friends who are electricians.
