The 2014 National Electric Code has mandated Ground Fault and Arc Fault circuit protection on many 15 & 20 amp kitchen and laundry circuits. General Electric's Dual Function Circuit Interrupter (DFCI) offers both Ground Fault and Combination Arc Fault (GFCI & AFCI) protection in a simple to apply and cost-effective solution. Dual function circuit interrupters utilize both GFCI and AFCI detection technology.
