Solution and Explanation
In damp or wet locations, electrical safety is critical to prevent shocks and electrical hazards. Hence, a Ground Fault Circuit Interrupter (GFCI) must be used. A GFCI detects any leakage current to ground and quickly disconnects the power supply to prevent harm. Insulation fault indicators detect insulation degradation but do not provide immediate disconnection.
