What is the key purpose of having GFCIs tested regularly?

The key purpose of having Ground Fault Circuit Interrupters (GFCIs) tested regularly is to ensure worker safety from electrical shocks. GFCIs are designed to detect imbalances in electrical current and shut off power to prevent serious injury or fatality from electric shock. Regular testing helps confirm that these devices are functioning properly and will activate when needed to protect individuals who may come into contact with electrical equipment, especially in environments where water is present, such as construction sites, bathrooms, and kitchens. By ensuring the reliability of GFCIs, employers can maintain a safer workplace and minimize the risk of electrical hazards, thereby prioritizing the health and safety of workers.
