What does GFCI stand for?

• A. Ground Fault Current Interrupter
• B. Ground Fault Circuit Interrupter
• C. Grounded Fault Circuit Interrupter
• D. General Fault Circuit Interrupter

Answer: (B)

GFCI refers to a device that protects you from electric shock by detecting when current leaks to ground and then shutting the power off quickly. The word parts line up with what the device does: “Ground” points to the earth path, “Fault” means an abnormal leakage, “Circuit” is the electrical loop being powered, and “Interrupter” is the mechanism that opens the circuit when a fault is detected. So Ground Fault Circuit Interrupter is the official term for this safety device. Other phrasings would describe different concepts and aren’t the standard name.
