- Breakers also usually have a fuseable link which is supposed to blow if
- the breaker doesn't trip rapidly enough. I have had one side of a GE
- breaker blow in this fashion without tripping. That was a double pole
- 20 amp; I don't know if the main breakers also have this feature.
-
- There also exist (or existed) breakers (can't remember the brand) which
- have a jointed steel rod for the tie. You can recognise these because
- they have what appears to be a ball bearing between the breaker handles.
- I have seen many of these trip only one side, but, again, these weren't
- main breakers.
-
- I've never seen a main breaker trip at all, but I have no reason to
- believe they would behave differently from the smaller ones.
