How is the main breaker different?

Hi,
This is just a theoretical question to satisfy my curiosity.
A panel can be back-fed through a regular breaker. How is a main breaker,
then, different from a regular breaker? Or is it just a breaker that
doesn't give you an option of not having it?
Thanks,
Aaron
"Main breaker" is defining it's usage, not necessarily how it's built. The
same thing with a breaker used as a service disconnect. The breaker is not
necessarily different from a similar type breaker used in the same panel,
however when used as a service disconnect, it requires a hold down method
Is there a technical reason why electrical panels with a main are so
much more expensive (at least at HD) than main lugs?
