What type of panel is this ??

[Catmando]

I saw this today. Haven't seen anything exactly like it. It's a General Electric panel ( with some Square D breakers ). The service line has one leg attached to a 70 amp breaker, and another leg attached to a parallel bus. The 70 amp breaker has two leads leading to lower areas of the bus. I want to call this a 70 amp service with a  split bus panel. I don't understand how the 70 amp breaker would act as a main shutoff.

It is a split bus panel.  A split bus panel does not have a main disconnect.

The service capacity is determined by the service entrance cable size and/or the rating of the main panelboard, not the 70-amp breaker.

Both service legs are attached to buses.  The 70 amp breaker supplies a separate pair of buses below.

Don't need a single main breaker, but there are supposed to be no more than 6 breakers/disconnects in the top part to shut off everything.  The one pictured has 7.

. . . and some split bus panels don't allow single pole breakers or tandem breakers in the upper section. See the schematic on the panel; it reveals all.
