Ground Fault Interrupters (GFI) in Bay Area
The idea of a GFI receptacle is that if there is the slightest electrical problem, the GFI immediately shuts off the power. This is an important safety feature.
More Technical Data About GFIs
A GFI receptacle (also called a GFCI receptacle) can measure differences in power as small as 3ma (which is a very small amount). When it detects more power coming in from the “hot” side than going out from the neutral side, it will shut off. This is a good thing because that extra electricity has to go somewhere, and it’s important to protect you and your family from it.
All GFI receptacles should be tested monthly. This is done by pressing the “TEST” button. If pressing the “TEST” button does not make the button labeled “RESET” pop out, then call an electrician. If the “RESET” button does pop out, the outlet is OK. Press the “RESET” button back in to reset the outlet.
