Final answer:
The statement that all receptacles serving kitchen countertops must be GFCI protected is true, as GFCIs are critical safety devices designed to prevent electrical shocks by detecting and interrupting circuit imbalances.
Step-by-step explanation:
True or False: All receptacles that serve kitchen countertops must be GFCI protected? The correct answer is True. A Ground Fault Circuit Interrupter (GFCI) is a crucial safety device that is commonly installed in places where electricity and water could potentially interface, such as in kitchens and bathrooms. The purpose of a GFCI is to protect individuals from electrical shock by detecting imbalances in the electrical current and interrupting the flow of electricity.
The GFCI monitors the amount of current flowing from hot to neutral and if there is any imbalance, it trips the circuit. This protection is especially important for kitchen countertops where appliances and water use are frequent. The National Electrical Code (NEC) mandates that GFCIs must be installed on kitchen countertop outlets in residential homes to mitigate the risk of electrical shocks.
