Ground Fault Circuit Interrupters (GFCIs) are the most effective at preventing major shocks due to their rapid response to changes in current paths.
Ground Fault Circuit Interrupters (GFCIs) are the most effective at preventing major shocks by detecting the loss of current to unintentional paths. They respond quickly to changes in current, opening the circuit rapidly to prevent shocks. Circuit breakers and fuses, while effective against thermal hazards, are not as fast or precise in preventing shocks as GFCIs.

D. GFCI (Ground Fault Circuit Interrupter)
A GFCI (Ground Fault Circuit Interrupter) is most effective at preventing major shocks because it quickly detects ground faults and shuts off the electrical circuit, preventing potential electrical shock hazards.
