I'd like to better understand the roles of main breakers and sub-breakers. Why are there multiple levels of breakers? I suspect that sub-breakers are intended to regulate/control electricity for specific sections of the house while allowing other sections to still be powered?
P.S. I'm SURE I'm misusing the term sub-breakers so I apologize to the electricians here. Hopefuly my question still makes sense. =)
