A Ground Fault Circuit Interrupter (GFCI) is designed to do which of the following? Select the best option. Detect ground faults Detect any amount of electricity Shut down the power to the entire grid upon detection of a fault If you need to review this content, it can be found in the Ground Fault Circuit Interrupters module of the Avoiding E (Construction) topic.

A Ground Fault Circuit Interrupter (GFCI) is a device designed to protect against electric shock and electrical fires by detecting ground faults. A ground fault occurs when the flow of electrical current leaves the intended path and enters the ground or a grounded surface. Option A, "Detect ground faults," accurately describes the primary function of a GFCI. Option B, "Detect any amount of electricity," is not specific enough, as GFCIs are not designed to detect any amount of electricity but rather to detect imbalances that may indicate a ground fault. Option C, "Shut down the power to the entire grid upon detection of a fault," is incorrect because GFCIs do not shut down the entire power grid; they only interrupt the circuit in which the fault is detected.
