True or False: Areas with an equipotential plane require GFCI protection.

An equipotential plane is designed to reduce the risk of electric shock in areas where there is a potential for high moisture, such as pools, spas, and other similar environments. In these areas, the ground potential is made uniform to minimize voltage differences between conductive surfaces that a person might touch. Because of the increased risk of electrical hazards in such locations, Ground Fault Circuit Interrupter (GFCI) protection is mandated. GFCIs are designed to quickly disconnect power when they detect an imbalance between the incoming and outgoing current, which can happen if there is an unintended path to ground, such as through a person.

The requirement for GFCI protection in areas with equipotential planes is especially important because it provides an additional layer of safety to prevent electric shock, ensuring that if any fault occurs, the circuit is interrupted swiftly to protect individuals in that environment. This safety measure is crucial regardless of the specific conditions such as wetness or the amperage of the circuits involved. Therefore, the statement about needing GFCI protection in areas with an equipotential plane is indeed true.
