Once again it is time change, for many of us, on Sunday. You get another hour of sleep and have to reset all the clock in the house.
Since you have to reset the clocks anyway, take the opportunity to actuate all the circuit breakers in the house - before you adjust the clocks.
Breakers that are never operated/tripped can freeze closed and not open if the is a problem with the circuits in the house - a stuck breaker could cause a fire. Flipping the breakers on and off every year reduces the chances that a breaker might freeze.
Don't forget the big breaker that interrupts all the current coming into the house.
Be safe,
Jim
