InterNACHI Electrical Practice Exam

The requirement for Ground Fault Circuit Interrupters (GFCIs) in kitchen countertops was established with the adoption of the National Electrical Code (NEC) in 1987. This change was significant because kitchens tend to have higher risks for electrical hazards due to the presence of water and other conductive materials. The 1987 NEC edition recognized this risk and mandated the use of GFCIs in areas where appliances and sinks might create potential electric shock hazards. By implementing this requirement, the code aimed to enhance safety in residential and commercial kitchens, making it essential for all new installations and renovations after this edition was adopted.
