The 60 amp breaker in the upper left shuts off power to the lower bank of breakers.


Four switches total for complete power shut off.

Thanks Jeff!


I worked that out..but I still do not want to believe it was done like this. This was the first I have seen it set up this way..it just does not make sense ....to me

Jeff, would I be correct in thinking that the box is a 170 amp box...the total of the four breakers when writing the load limit in the report?

The box should have its rating marked on it somewhere.

The service amperage is 60 amps (that would be my call). The other breakers are for load side equipment (sub panels, A/C, etc.).

Can someone explain what the wires from the upper left breaker are doing in photo #3 and how they are attached below?

Supplying power the the bus bars of the lower breakers.

But how is it attached to the bus bars?

They appear to be soldered.

Was that common and acceptable in the past?

I've not see that but once and when I did I thought it was cobbled together.

This is what is called a split bus panel. NEC requires 6 pulls or less to shut off all power. I see these all the time. The manufacturer did this to save cost. A 60 Amp double pull breaker for the lower bus is cheeper than a 100 Amp main disconnect. By the way, you never get total amp size by adding the amps on the breakers.
