What is the primary function of a GFCI protected receptacle?

• A. To provide standard power supply
• B. To protect against electrical shock
• C. To allow multiple devices
• D. To increase voltage supply

Answer: (B)

A GFCI (Ground Fault Circuit Interrupter) protected receptacle primarily serves to protect against electrical shock. It is designed to detect imbalances in the electrical current flowing through the circuit, which can occur if there is a ground fault—essentially when electricity travels outside its intended path, such as through a person's body to ground. When the GFCI senses this imbalance, it quickly shuts off the electrical supply to the receptacle, significantly reducing the risk of serious injuries or fatalities from electrical shocks. This safety feature is particularly important in areas where the risk of electric shock is higher, such as kitchens, bathrooms, and outdoor locations. The ability of a GFCI to interrupt power in microseconds makes it a crucial element in home and workplace safety, ensuring a safer environment for users.
