2014 NEC Code change tightened the requirements on ground fault and arc fault protection on 15 and 20A kitchen and laundry circuits. This applies not only to new construction, but also to existing homes. The GFCI circuit interrupter provides protection against overloads, short circuits and ground faults. It detects very low levels of electrical current leakage (ground faults), and acts quickly to shut off power, preventing serious shock. An arc fault is the flow of electricity over an unintended path. faults. An arc fault is the flow of electricity over an unintended path. These arcs can exceed temperatures of 10,000° F and easily ignite combustible materials in the home. AFCIs are devices that protect your home by detecting dangerous arcs and safely de-energizing the circuit.
GE's GFCI and AFCI provide great protection from both shock and fire hazards
- GFCI Specifications
- Class A 5mA Ground Fault Circuit Interrupter
- 1 or 2 pole
- 15A, 20A, 25A, 30A, 40A or 50A
- 120 Vac or 120/240 Vac
- Wire Range #14-8 AWG CU / #12-8 AWG AL

- AFCI Features
- Parallel protection − Just like its Branch/Feeder counterpart, Combination AFCI can detect and neutralize parallel arc faults
- Series Protection − A series arc fault is the unintended flow of electricity over a gap within a single wire. These arc faults were not detectable until advanced technology allowed the development of the Combination AFCI breaker.
- Ground protection − Arcing between a single conductor and a ground line
- Overload protection
- Short circuit
