A ground fault occurs when electricity takes an unplanned path to ground. The current drastically increases and causes the breaker to trip. A ground fault can be caused by damaged appliances, incorrect wiring, or worn wire insulation.

What causes a ground fault circuit breaker to trip?
If the GFCI's internal current transformer senses more than a 4-5 milliamp loss, it instantly shuts down the outlet and any outlets it feeds to prevent accidental electrocution. Most often, when a GFCI “trips” it is the result of a faulty appliance plugged into the outlet or an outlet down circuit.
What to do if GFCI keeps tripping?
- Unplug all the appliances connected to the circuit in question. - Reset the circuit on your fuse box. - Wait several minutes. - Plug an appliance back in and turn it on. - Check to see that your circuit has not tripped.
What is the most common cause of ground faults?
The usual suspects for ground-faults include worn insulation, conductive dusts, water, or other "soft grounds." Ground faults account for more than 80% of equipment short circuits and in 90% of those cases it is caused by insulation deterioration on wires and cables.

How do you fix a GFCI that keeps tripping?
- Unplug all the appliances connected to the circuit in question. - Reset the circuit on your fuse box. - Wait several minutes. - Plug an appliance back in and turn it on. - Check to see that your circuit has not tripped. - Plug in the next appliance, turn it on, check the breaker, and so on.
What causes a GFCI to trip repeatedly?
The usual suspects for ground-faults include worn insulation, conductive dusts, water, or other "soft grounds." Ground faults account for more than 80% of equipment short circuits and in 90% of those cases it is caused by insulation deterioration on wires and cables.
What are the common causes of ground fault?
Ground faults can be caused by water leaking into a breaker box, damaged wires or appliances, poorly insulated or damaged wires, or even a build-up of debris within a box. Ground faults can lead to disastrous results such as electrical shock, fire, or burns.
Overcurrent, Overload, Short Circuit, And Ground Fault
How does water cause ground fault?
Water leaking into an electrical box can cause a ground fault, since water is a conductor of electricity. Worn hot wires or hot wires that are not completely seated into their terminals may come into contact with ground wires or grounding devices or boxes.
How does a ground fault work?
A ground fault circuit interrupter (GFCI) can help prevent electrocution. If a person's body starts to receive a shock, the GFCI senses this and cuts off the power before he/she can get injured. GFCIs are generally installed where electrical circuits may accidentally come into contact with water.
Why Does My Gfi Keep Tripping?
Can a loose wire trip a GFCI?
Loose wires or other faults within the equipment that's plugged into the outlet can cause grounding issues that will trip the GFCI. It may not be evident if the equipment gets unplugged often or if you unplug it before attempting a reset, and it may not trip the GFCI consistently.
What causes a GFCI to trip with nothing plugged in?
What could be causing it ? Typically there are other outlets on the same circuit with the GFCI outlet. The problem device could be plugged into one of those other receptacles. Typically there are other outlets on the same circuit with the GFCI outlet.
