Which of the following is a primary function of workplace GFCIs?

The primary function of ground fault circuit interrupters (GFCIs) in the workplace is to prevent electrical shocks. GFCIs are designed to detect imbalances in electrical current, which can indicate that electricity is flowing through an unintended path, such as a person who is accidentally grounded. When such a fault is detected, the GFCI quickly cuts off the electrical supply to reduce the risk of electrocution or severe injury.

This protective mechanism is particularly important in environments where water is present, such as kitchens, bathrooms, and outdoor areas, since wet conditions heighten the risk of shocks. While GFCIs do not regulate power consumption, provide additional outlets, or directly enhance equipment efficiency, their role in safety is critical for preventing accidents and safeguarding workers from electrical hazards.
