Product FAQs
6 answersWhat load centers are UL classified to accept the Eaton CLCAF120?
This 1-inch classified breaker is UL listed for use in specific competitor plug-on load centers, including Square D Homeline, Siemens Type QP, Murray Type MP, and General Electric Type THQ panels. It is not designed for use in Eaton BR or CH panels.
How is the neutral connection handled on this AFCI breaker?
The CLCAF120 features a pigtail neutral. The coiled white wire must be connected directly to the neutral bus bar in the panel to ensure proper arc fault detection and operation.
What does combination arc fault protection mean for this breaker?
As a combination type AFCI, it detects both parallel arcs (line to neutral or ground) and series arcs (loose connections within a single wire). This provides comprehensive protection to meet National Electrical Code requirements for living spaces.
What wire sizes and materials are compatible with the box lugs?
When wiring the CLCAF120, the box lugs accommodate 14 AWG through 4 AWG conductors. The terminals are rated for both aluminum and copper wire.
Can I use the CLCAF120 to replace a standard 20A breaker in a classified panel?
Yes. If you need to upgrade a standard 20A circuit to meet current AFCI code requirements, this breaker serves as a direct replacement in approved GE, Siemens, Murray, and Square D Homeline load centers.
What is the interrupting rating of the CLCAF120?
This breaker has a 10kAIC rating at 120/240VAC. It is designed for residential and light commercial applications where the available fault current does not exceed 10,000 amps.
