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
