Per code, there are a minimum of four (4) GFCI receptacles in your house. GFCI stands for Ground Fault Circuit Interrupter. In layman's terms this device protects you from electrical shock. When it senses the slightest increase in resistance resulting from ground fault, (i.e., the use of electrical devices in or near water), it trips or shuts off to protect you.
The GFCI house circuit is typically the receptacle located next to the main electrical panel in the basement (or sometimes garage). This typically protects your basement, garage, utility and exterior weatherproof receptacles. Note: Receptacles on dedicated circuits and for the garage door openers are NOT protected by this circuit.
The GFCI bathroom circuit is typically located in the master bathroom (or sometimes hall bath) and typically protects all standard bathroom receptacles including your powder room(s).
Per code, there are two GFCI kitchen circuits with the GFCI receptacles typically located at the main counter area. These circuits protect the standard kitchen receptacles and many times some of the breakfast and dining area receptacles.
Please note: refrigerators and other heavy duty appliances such as power tools that are plugged into a GFCI protected receptacle may cause the circuit to trip due to the current they draw.
