Just a very general question for information purposes. I had a 100 amp subpanel installed to our detached garage a couple of years ago. To cut off all power to the subpanel in order to replace or add a circuit breaker, is it best to flip the main breaker in the main service panel at the house (thereby cutting off all power to everything), or just switch off the breakers inside the main panel that serve the subpanel? Or simply flip the main breaker inside the subpanel itself?
Just curious what is considered normal safe practice for future reference in case I have someone do some electrical work for the garage circuits.
