During an inspection, what is the function of a GFCI outlet?

A Ground Fault Circuit Interrupter (GFCI) outlet is specifically designed to prevent electrical shock, particularly in areas where water is present, such as kitchens, bathrooms, or outdoor locations. The primary function of a GFCI outlet is to monitor the flow of electricity and quickly cut off power if it detects an imbalance between incoming and outgoing current. This typically happens when electricity finds an unintended path to the ground, which can occur if a person is in contact with water and an electrical source. By tripping the circuit very rapidly (in as little as 1/40 of a second), GFCI outlets protect individuals from potential electrical hazards and reduce the risk of severe injuries or fatalities due to shock.

The other options do not accurately represent the purpose of a GFCI outlet. Enhancing electrical capacity refers to increasing the overall power supplied to a circuit, which is not within the scope of a GFCI's function. Regulating power consumption involves managing how much energy is used by appliances or systems, but GFCI outlets are not equipped to control electrical consumption. Providing better light switches implies improving the functionality of lighting controls, which is unrelated to the protective qualities that GFCI outlets offer. Thus, option B correctly identifies
