  1. Once
  2. Ten times
  3. Three times ✔

Why: Circuit breakers should be exercised periodically so they do not stick and stay in good working order. First turn off the freezer, refrigerator and air conditioner, because repeated power interruptions can damage compressor motors.

Huh, didn't know that: CPSC warns that a fuse of the wrong size for its circuit can let too much current flow and overheat the wiring, creating a fire hazard.
