Catmando Posted August 8, 2017 Report Share Posted August 8, 2017 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. Quote Link to comment Share on other sites More sharing options...
Jerry Simon Posted August 8, 2017 Report Share Posted August 8, 2017 (edited) 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.

Jim Katen Posted August 9, 2017 Report Share Posted August 9, 2017 . . . 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. Quote Link to comment Share on other sites More sharing options...
