Why a GFEP (GEFP, RCCB, or heat trace circuit breaker) and not a GFCI breaker for WarmlyYours outdoor deicing and snow melting systems?

GFEP is the National Electric Code (NEC) required protection for fixed outdoor deicing and snow-melting equipment, which may be accomplished by using circuit breakers equipped with ground-fault equipment protection (GFEP) of 30 mA. It is important to understand that this required equipment protection is NOT the same as a 5 mA GFCI used for personal protection.
