The GFI switch, also known as the Ground Fault Interrupter switch, is an electrical device that has the duty of preventing electrical shocks and fires by detecting a ground fault and then automatically tripping off the power supply.

A GFI switch, or Ground Fault Interrupter switch, is a device designed to protect against electric shock by quickly cutting off power if it detects a fault in the circuit. It is commonly used in areas where water is present, such as kitchens and bathrooms, to prevent electrical accidents.

For all regular gfi outlets, the power travels through two wires. Think of it as a wire coming from the power company, delivering power to the appliance, and a wire going back, sending any leftover power to be reused.

Now, the earth is a huge mass, which can absorb a lot of electricity, and it will do so gladly. If lightning hits a tree. the power is transmitted through the tree to the earth. Usually the tree doesn't fare very well. The earth doesn't seem to mind at all.

Likewise, if a person is well grounded, by standing on wet ground, touching a grounded pipe or object or soaking in a tub, and they come in contact with electricity, it can travel through them to reach the ground. This can cause intense pain, burns and, sometimes, death.

A GFI has a very sensitive detector that notices if any of that power that came in isn't going back to the power company. It assumes that it is going to ground and shuts off. Wet appliances, wet outlets, frayed wires, evn excess damp in the air can cause GFIs to trip.

A GFI can also protect outlets that are "downstream" of it. If other outlets are wired to it, they will cause the GFI to trip if a ground fault occurs.

Why do CFL's keep blowing in my lamp that is pluged into a GFI outlet?

CFL bulbs can be sensitive to fluctuations in electrical currents, which may be more common with GFI outlets. It's possible that the GFI outlet is causing the CFL bulbs to flicker or blow out due to the way they regulate electrical flow. Consider using LED bulbs instead, as they are less sensitive to these fluctuations.


GFI electrical outlet at the garage where the freezer hook up keeps on tripping but when plug at the electrical outlet of the garage door openner does not trip. What is mostly the problem?

The GFCI outlet in the garage where the freezer is plugged in may be faulty or overloaded, causing it to trip. It's possible that the outlet for the garage door opener is on a separate circuit and not affected. Check the load on the GFCI outlet, inspect for any damage, and consider replacing it if the problem persists.

How do you find a triped circuit?

A tripped circuit is typically identified by a switch in the electrical panel that is in the "off" position, or a fuse that is visibly blown. You can reset a tripped circuit by flipping the switch back on or replacing the blown fuse. Make sure to investigate the cause of the trip before resetting to prevent any potential hazards.


Do both the breakers and the outlets need to be GFI if you are running two 15 amp GFI circuits?

If you're using a GFCI breaker then the entire circuit will be protected by just the breaker alone. Every receptacle, switch, etc on that breaker will utilise the GFCI protection. You may have problems with it tripping if you plug in a motor (vacuum, etc) on the circuit.

How does a GFI switch work?

An electric flow-monitoring switch (GFI switch) detects the difference between the entering and exiting current. So, it is concluded that if the breaker detects some difference then it indicates that the current is flowing through an undesirable path like water or a person is the case, so, it cuts off the power immediately, thus preventing the danger.

How do you wire a garbage disposal between the disposal and the GFI?

White and the ground go to the disposal, black goes through a switch and then to the disposal. All three go through the switch box, the white and ground just pass through on the way to the disposal. Break the black with the switch.


What is the solution for a refrigerator that is tripping the GFI?

When wiring a house, GFI plugs are strategically placed in areas that can be tripped by water. For example: in bathrooms, in garages, etc. There are certain areas that do not require GFI plugs. A refrigerator is one device that is usually on its own breaker and does not require a GFI plug. My recommendation is to locate where the refrigerator is. If it is in the house remove it and replace it with a non GFI plug.
