Square D by Schneider Electric Homeline 20 Amp 1-pole Plug-on Neutral Dual Function Circuit Breaker is a space and labor saving device, engineered to meet prevailing National Electric Code requirements. This device combines 2-critical technologies, Combination Arc Fault protection (CAFCI/CAFI) and Ground Fault protection (GFCI/GFI - class A), in a single, easy-to-install device. The National Electric Code now requires both Combination Arc Fault and Ground Fault protection on all 1-Pole, 15 Amp and 20 Amp kitchen and laundry circuits. The new Dual Function circuit breakers eliminate the hassle of using 2-separate devices to provide this essential protection. Designed for reliability, the Homeline Plug-on Neutral Dual Function Circuit Breaker connects directly to the neutral bar, providing a time and labor-saving installation. Several advantages from the Plug-on Neutral design are fewer connections which lead to faster installation and an innovative neutral clip eliminates pigtails which in turn frees gutter space. This breaker is only compatible with Square D's Homeline Plug-On Neutral electrical panels with available space for a 1-pole breaker. A total of 9-spaces required for entire offering. Like all Square D CAFI Circuit Breakers, it is integrated with time saver Diagnostics, a unique feature that provides additional circuit information and minimizes troubleshooting at the touch of a button. This breaker is designed for residential and single phase commercial uses.
