What device is designed to protect against ground faults?

The Ground Fault Circuit Interrupter (GFCI) is specifically designed to protect against ground faults, which occur when there is an unintended pathway between a power source and a grounded surface. GFCIs continuously monitor the electrical current flowing through a circuit and can detect imbalances, typically caused by a ground fault. When such an imbalance occurs, the GFCI quickly cuts off the electrical supply, effectively preventing electric shock or electrocution hazards. This protective mechanism is crucial in healthcare settings where exposure to moisture and bodily fluids can increase the risk of electrical hazards.

Other devices, such as surge protectors and power strips, serve different purposes. Surge protectors are designed to shield electrical equipment from voltage spikes by diverting excess voltage, while power strips simply provide multiple outlets for devices without offering ground fault protection. Voltage regulators maintain a constant voltage level to prevent equipment from receiving too much or too little voltage, but they do not address ground fault issues. Therefore, the GFCI stands out as the essential device for protecting against ground faults.
