GFCI
GFCI (Ground Fault Circuit Interrupter) is a safety device that protects people from electrical shocks. Think of it as a very fast safety switch that turns off power when it detects problems. You'll often see these in bathrooms, kitchens, or outdoor areas where water might be present. When candidates mention GFCI in their resumes, they're showing they understand electrical safety requirements. Similar terms include GFI (Ground Fault Interrupter) or RCD (Residual Current Device) in some countries. This knowledge is especially important for electricians, electrical contractors, and safety inspectors.
