I had trouble with my breaker panel and it was at night. The panel was really messed up. Until the guy could get back the next day, he rearranged or replaced some breakers or something so it would work overnight and at least until he could get back and really fix it correctly. When he came back and replaced it, everything worked fine and I at least felt confident I wouldn't have any more problems. I felt like it was all done right and like I understood why it was necessary. I didn't want to lose power again anyway and I don't think I will.
