I do not Know how to line up the above chart with the days,sorry about that.
I think we call it something different here, Ground Fault Interruper.
If so, we had something similar happen when we lived in Jerusalem. The electrical standards are very poor there, electric fuze boxes build on wood, wires run through plastic tubes that collects moisture and the GFI continually went off, so much so I had to externally wire power to a living room light so we would at least be able to see inside at night, bypassed the GFI. You may have something like that going on, each CB should have its own GFI on it so it should not take out the whole house unless you have a whole house GFI, not sure about that, but it may be due to condensation in some wiring. You can troubleshoot it by removing wires one at a time after cutting power, turn power on and wait till next day and see if it goes off again. Keep doing that till you find the offending wire. Good luck. Don.
