Tecmark Corporation
Understanding HF-Rated GFCI Protection What is the HF note?. As the NEC now requires Ground Fault protection for a larger scope of applications & higher rated circuits in the recent Code cycles, high frequency during start up & cool down phases of equipment involving power inverters & variable frequency drives (VFDs) has created issues with inadvertent fault conditions. This is because the High Frequency "chatter " in the circuit is seen as electrical leakage by the GFCI. High Frequency (HF) rated Ground Fault Circuit Interrupters...
