Ground Fault Interrupt Circuits

All About Ground Fault Interrupt Circuit (GFCI)

Ground Fault Interrupt Circuits (GFCI) are electrical safety devices that protect people from electric shocks and fires caused by ground faults. A ground fault occurs when electricity leaks from a circuit and flows to the ground through an unintended path, such as a person’s body, a wet surface, or a damaged wire. A GFCI detects this leakage and quickly shuts off the power to the circuit, preventing serious injuries and damages.

Since 1980, the GFCI building code requirements have expanded. Previously only used on construction sites, GFCI’s are now required in many different rooms of your home, especially those with moisture – washrooms, kitchens, pool areas, etc.

The GFCI monitors the input and output levels being passed through an outlet. If there is a slight difference in the current being transferred from the hot outlet to the neutral outlet, then the device will quickly cut off the power supply to prevent damage or injury. A GFCI can detect changes in current supply as minor as a few millamps. GFCI’s are a simply advancement in technology that could potentially save lives or prevent injury to your family.

If you need assistance installing a GFCI or determining the appropriate rooms to upgrade your outlet to a GFCI outlet, please contact Expert Electric. 604-681-8338
