Zinsco commercial breaker

[electricguy61]

I have a commercial customer with a cursed Zinsco panel. It has a 400amp main switch and a model BSS40-4SN distribution panel.

Does anyone have access to older spec sheets that would tell me what breakers this panel will use? Existing breakers are 3 pole 200amp and 3 pole 100amp. I want to run 70amp single phase (it's a 240v delta system) to a sub-panel.

Thanks

Try a "classified" breaker supplier like T&B for those sheets, other than that? Good Luck!

I'm not sure if they have access to the info you are looking for, but these guys have helped with some odd ones in the past:

Thanks for the response. Are you referring to the T&B buying guides?
