JKB, it is fine to talk about CB on another thread but correct me if I am wrong. You turn off all energy sucking machines then turn off all Circuit breakers,then turn breakers back on,then machines gradually. That is how we do them here but we stay away from the main breaker. Tell me if I need to do something different.
Drop everything out before dropping out your main CB, if you will be doing maintenance or working on your wiring. The reason for a main Circuit Breaker is that you can kill power to everything at one flip of a switch. This is extremely valuable for the public servants that help us in crisis.
I am working out my electrical scheme, and for the most part, it has been positive.
