What is a Ground Fault?

It's job is to cause breakers or fuses to trip, in order to clear a short. When this wire constantly Conducts electricity, It is referred to as ground fault.

Why Should I Have Ground Fault Protection?

Ground Fault Protection devices, such as GFI outlets and circuit breakers, turn off the circuit when the detect electricity flowing on the ground wire. These devices can even detect the current without the bare wire being present, by using electronic calculation of any imbalance between the "hot" or "phase" wire and the "neutral" wire. If there is any difference in current between the two wires, the device will determine that the energy is going to ground, causing it to shut off. The usual setting of these devices is five milliamps. That's only five one thousandths of 1 amp! 0.005 amps! Not even the smallest amount of electricity escapes these devices.
