Which acronym stands for Arc-Fault Circuit Interrupter?

Back

AFCI

Answer explanation

The acronym AFCI stands for Arc-Fault Circuit Interrupter, which is designed to prevent electrical fires by detecting arc faults. The other options (ALCI, GFCI, OCPD) refer to different types of circuit protection devices.

Front

What is the correct full term for GFCI?

Back

Ground-Fault Circuit Interrupter

Answer explanation

The correct full term for GFCI is "Ground-Fault Circuit Interrupter." This device is designed to protect against electrical shock by interrupting the circuit when it detects a ground fault.
