220 breaker from 2 110's?
Again, I'm a little confused as to how to properly describe this, but here it goes. Inspection at a condominium complex yesterday and I'm looking at the panel. There is a "regular" sized 20amp breaker with a "handletie" (of sorts) to one side of a 20amp twin breaker. They are servicing a baseboard heater. This just seems very wrong. Any opinions?

It does not appear to be an OEM handle tie from Square D for their QO series breaker.
The handle tie needs to be listed for that application which I doubt that it is.
I am not aware of any OEM, listed handle ties approved by SqD for use in this application. I don't think the twin on the bottom has the pulling power to trip the upper breaker.
Easy fix, write it up.

Jeff,
It looks like those handles ties Square D first came out with. They had a circular disc in the middle, with tapered sides, and small diameter ends sticking out each side. I never liked them because they were a bit floppy, but they were from Square D and they did externally trip the other half when one half tripped ... at least most of the time (occasionally they would not)
See them here: square D qo handle ties - Google Product Search

Not good, fix it.
I would venture to guess that space was tight in the panel and the jury-rig was done to make everything fit and avoid replacing the panel or more breakers. I doubt Square-D would approve.

I would start with Who manufactured the panel and the breaker? Not compatible "write it up"
