Is this a split-bus panel?

This electrical panel is wired as though it were a split bus, but it doesn’t look like the omni bars are actually split. I believe that would mean that this panel does not have main overcurrent protection. Is there some way I can tell without removing breakers? I’m obviously not removing breakers

Need a better picture to make any decision.

What exactly gives you that impression?

From what little I can see, it appears to be a ‘standard’ sub-panel with double-lugged neutrals!


Where was the main disconnect? At the Meter perhaps?

There is no main disconnect at the meter, and I have the impression that the omnibus bar is not split because the bracket onto which the breakers are clipped it not split. I know that the bracket and the bus bars are not connected, however I do not recall ever seeing a CH split bus panel where they are connected. That seems contrary to the normal redundancy electrical engineers build into systems. What picture would make things more clear?

A picture of the whole panel.

Ok. Hang on. Let me get off this roof

Yes, looks like split-bus. The double 60A, second down on the left side wraps to the bottom and energizes the lower part of the bus. Some split bus type panels done have a physical gap between the breakers but if you were to remove all the breakers you’d see the bus bars have a break… or a “split” I suppose one could say.


I agree with Matt.

So, I’m with y’all that it is wired like a split bus. The question I am asking is if the bus is split. Like, are the pieces of metal for the main section and general section detached. An electrician could wire a non-split bus as though it were and really screw some things up

Like is it clear that I’m not asking how the panel is wired, I’m asking how the panel is built?

Turn OFF the 60 amp breaker, and if all bottom circuits go dead, you will have your answer… OR… you can start pulling breakers to get an actual eyeball on things!

Turning off the breaker was an elegant solution! When I turned it off, all of the outlets and appliances still had power, so it WAS incorrectly wired

What about the lights? I see the 60 amp appears to be labeled “Lighting Main.”

This one looks just like the one you have. From the first page of results on google for “split bus panel”
The video shows that the bus bars are physically separate, so I’m not sure how you still have power. 240V appliances will still have power as they are on the top bus bar section. 120V lights and receptacles shouldn’t have power though…

How would it be incorrectly wired? Could there be another sub-panel?


Just had one today where some well-meaning homeowner incorrectly labeled the 60A “sub main”, “lighting main”, whatever, the “master power whole house”. Those panels came with sheets of stickers and people often misunderstood how the panels worked and put the wrong sticker in the wrong place. Having a breaker labeled “main” and having it not be the main is a pretty big problem IMO given the minimal understanding your average homeowner has.
