Delivering advanced residential safety, the HOM215CAFI provides combination arc-fault protection for 120/240V circuits. This 15A, 2-pole breaker detects and mitigates hazardous arcs to prevent electrical fires. It mounts into Square D Homeline load centers using a standard plug-on connection. The unit includes a pigtail neutral wire for straightforward installation. Rated for 10 kAIC, this thermal-magnetic breaker is UL listed, HACR rated, and accepts 14-8 AWG wiring.
Can I install the HOM215CAFI in a Square D QO load center?
No. This breaker is exclusively designed for Square D Homeline load centers. QO panels require a different bus bar connection and use QO series breakers.
Does this breaker require a pigtail connection to the neutral bar?
Yes. The HOM215CAFI features a pigtail neutral wire that must be manually routed and secured to the panel neutral bar. It is not a Plug-on Neutral breaker.
What types of circuits require a 2-pole combination arc-fault breaker like this one?
A 2-pole CAFI breaker is typically used to protect multi-wire branch circuits that share a single neutral wire, or dedicated 240V appliances that require arc-fault protection under the National Electrical Code.
What does the HACR rating mean for this 15A breaker?
The HACR rating indicates this breaker is approved for use with heating, air conditioning, and refrigeration equipment, provided the equipment nameplate specifies a 15A maximum overcurrent protection device.
Can I terminate two copper wires under a single lug on this breaker?
Yes. The clamp terminals are rated to accept two 14 AWG to 10 AWG copper conductors, which is useful when feeding multiple loads from the same pole.
What is the difference between the HOM215CAFI and the HOM215PCAFI?
The HOM215CAFI uses a pigtail neutral wire that connects to the neutral bar. The HOM215PCAFI is the Plug-on Neutral version, which connects directly to the neutral bar without a pigtail, requiring a compatible Plug-on Neutral Homeline panel.
What type of arc-fault protection does this CAFI breaker provide?
As a Combination Arc-Fault Circuit Interrupter, it detects and mitigates both parallel arcs, such as line-to-neutral faults, and series arcs, such as loose connections, to prevent electrical fires.
