What’s a GFI?

A GFI is an abbreviation for a Ground Fault Interrupter. It is a specially designed outlet normally used in locations where moisture can accumulate, such as kitchens, baths and laundry areas, to protect you from electrical shock. A GFI measures the resistance on the “positive” and “negative” loads connected to it, and if there is more resistance in either of the 2 loads, the GFI trips. The GFI has a built-in circuit breaker to reset once the problem has been resolved.
