Carling Equipment Earth Leakage and Ground Fault Circuit Breakers combine the earth fault protection of GFCI with the overcurrent tripping characteristics common to conventional circuit breakers. PB and PC Series Circuitry GFCI circuit breakers have current ranges of 10 to 50 amps and are well suited for use in the marine industry as AC branch ground fault protection, AC main circuit ground fault protection, and portable generator ground fault protection.
