Best Answer

The most common one you see around your home is the GFI outlet, (ground-fault interrupter), which monitors the balance of electricity going through the plug. If there is an imbalance, the switch will 'trip' and shut off the current. Another electrical safety device a plastic plug that is inserted into an unused electrical outlet to prevent children from sticking things into the plug holes and getting electrocuted. The third item is the breakers that control electrical current to the different parts of your home. This works on a larger scale, but is similar to how a GFI outlet works. Instead of monitoring just one plug, a breaker protects an entire circuit (or electrical zone) of a home or building.
