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



It's bolted in place. (you can use a regular breaker as a main, but
it's supposed to be bolted in -- there's an inexpensive kit for doing that)
