Ground Fault Circuit Interrupters (GFCIs), whether installed as outlets or branch circuit breakers, provide essential electrical safety by disconnecting power when a ground fault is detected. While traditional GFCI devices were designed to operate effectively at 60 Hz, many of today’s appliances and HVAC equipment generate higher-frequency electrical signals. To support these modern loads, Leviton has enhanced its GFCI outlets and branch circuit breakers with improved high-frequency interoperability, helping reduce unwanted tripping while maintaining reliable ground-fault protection and seamless performance in today’s electrical environments.
