The Air Conditioning Contractors of America (ACCA) announced that it has achieved the National Fire Protection Association (NFPA) exemption of all outdoor HVAC equipment from the 2020 and 2023 National Electrical Code (NEC) Ground Fault Circuit Interrupter (GFCI) protection. The exemption is in place until September 2026.
This achievement stems from a two-year-long campaign of proposals and appeals submitted to the NFPA Standards Council by ACCA, Leading Builders of America (LBA), and the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).
