Not necessarily. As another poster alluded to breakers don't always trip. There was an incident with my girlfriends hairdryer at my parents house a couple years ago. The hairdryer's cord/breaker shorted out and caught on fire, the GFCI outlet didn't trip, and neither did the breaker. It can take minutes (or hours) for a breaker to trip depending on the situation, plenty of time for a fire to start.Bypassing the breakers would just mean the fuse powering the garage inside the house would blow if there is an overload
