Why does this type of panel have two main breakers?

Fairly common in canada (Westinghouse Novaline, Cutler-Hammer, Challenger too from what someone else said) to have panels with breakers that look like that. I can't say for sure 100% in that case, but they do make one peice (for lack of a better word) breakers that look like that... basically two tandem breakers stuck together with some configuration of handle ties. The two I've seen are like that one above, in a 1-2-1 configuration (single pole, double pole, single pole), and also in a two double pole format with a large handle tie around the outside to give you 2 double pole breakers. The only catch is they are non-common trip.. says so right on the breaker.

I have a CH panel in my own home with these kind of breakers. Here's a pic... if you squint closely you can see the diagram on the breaker that shows the handle tie setup and it says "non common trip."

I repeat Bizzaro
Joe you tagged it, as I was a big Superman DC comics fan as a kid.
Heck I would most likely still enjoy them.
Thanks for explaining that, guys as nobody was answering the question and I have never seen that kind of setup.

Thanks guys,
I will be visiting this place again tomorrow morning and will pull more info from the panel and take some more pictures. I will follow up on this post. It is my guess that the 60 amp breaker most likely feeds the sub panel in the basement.
Thanks again for your imput.

Now it makes sense.
Inside is so important,one of the many reasons I take close to 200 pics a job.
Nothing like good macro.

Why two different amperages tied together like this and is the solid ground wire proper? When the doorbell circuit is double tapped do you call it out or is it OK as in this arrangment?
