A ground fault occurs when electrical current unintentionally flows to the ground or a grounded surface. This can happen due to damaged insulation, moisture, or faulty wiring, creating a path for the current that bypasses the intended circuit. Ground faults can pose serious safety risks, including electric shock or fire hazards. To prevent ground faults, devices like Ground Fault Circuit Interrupters (GFCIs) are used. These devices monitor the flow of electricity and can quickly cut off power if they detect an imbalance, indicating a ground fault. Regular maintenance and inspections of electrical systems can also help reduce the risk of ground faults.
