I lived in Europe where it is common to have on/off switches on all electrical wall outlets. I asked my electical parts store if I could replace the cicuit breakers in my home with switch rated (swd) breakers.
I was told that I would have to replace my entire panel as swd circuit breakers need a panel made specifically for there use.
My reasons for wanting to turn off all power when I'm not home are - our homes are filled with appliances and devices from various world-wide sources that are not always reliable especially when some of those items may be decades old. I know these items sometimes cause fires even when connected to proper circuit protection. Our homes are sometimes invaded by critters (mice, squirrels and others) that are attracted to the insulation on wiring. They have been the cause of home fires.
Is there a basic on-off power disconnect switch that could be installed upstream from my service panel? It is not likely that I will unplug all my appliances whenever I leave my home, that would involve pulling refrigerators, washing machines, etc. out from the walls to get access. I need a system disconnect switch.
