As NEC expands ground fault protection, high-frequency noise from VFDs and inverters can cause nuisance GFCI trips. HF-rated GFCIs address this by adjusting leakage thresholds based on frequency, allowing safe operation without false trips. Codified in UL 943 for the 2026 NEC cycle, they work with UL 101-listed equipment to ensure compliance and reliable protection in high-frequen... Read more...
