zinsco panel help
Hello, i have a zinsco panel that has no main breaker and a 50amp breaker on top half of panel feeding 2 lugs at the bottom of panel. Is this a split bus panel and how does this panel work. Any information on this subject is greatly appreciated

It sounds like it might be a split buss but a pic could confirm. You could also look at the wiring diagram that should be on a sticker in the panel.
A split buss panel allowed typically 6 double pole breakers for the larger loads like dryers, stoves etc. These breakers together were acting as a main breaker under the 6 throws of the hand rule. There was one that fed the lower buss where your loads like lighting and receptacles were fed.

ty pcboss for your reply have another ? maybe u can help
trying to install 70amp subpanel in basement, there are 2 open slots in middle of main panel, however the metal tabs of the 70amp breaker i got do not line up with the bus bars. It looks like i would have to move some single breakers from bottom half of panel up to make this work. The question i have is if i do this this means the 70amp breaker will be on the bottom half of the panel which is being fed from a 50amp breaker i take it this will not work or do i have any other options to try to make this work. Thank u for ur help

My guess based on what you've provided so far is that there is no legal or safe way to add a 70A subpanel to this obsolete Zinsco split-bus panel. What do you intend to power with this subpanel, basic lights and receptacles or a large tool or appliance?
Can you post some links to pictures of the panel? Here is a guide: http://www.doityourself.com/forum/el...your-post.html

If you are just adding some basic stuff there is no need for a 70 amp subpanel. How many items are you thinking about adding? How many circuits?
