Product FAQs
6 answersWhat panels are compatible with the BR120AF?
The BR120AF is designed for use in Type BR load centers. It is also UL approved as a direct replacement for older Westinghouse, Challenger, Bryant, and Cutler-Hammer panels that accept Type BR breakers.
How do I connect the neutral wire on the BR120AF?
This breaker features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the neutral bus bar in the panel, while the circuit's neutral wire connects to the breaker's neutral lug.
Can I install this pigtail breaker in a plug-on neutral panel?
Yes, you can install a pigtail AFCI breaker in a plug-on neutral panel. However, you will not utilize the plug-on neutral feature and must manually connect the pigtail wire to the neutral bus bar.
What type of protection does the BR120AF provide?
The BR120AF is a branch/feeder Arc Fault Circuit Interrupter (AFCI). It is designed to detect unintended electrical arcs in the circuit to help prevent electrical fires, providing protection that standard thermal-magnetic breakers may not catch.
Does the BR120AF require a dedicated neutral?
Yes, AFCI breakers generally require a dedicated neutral for the circuit they protect. Sharing a neutral with another circuit can cause nuisance tripping and prevent the breaker from functioning correctly.
Is the BR120AF a branch/feeder or combination AFCI?
The BR120AF is an older branch/feeder AFCI model. In many modern applications, it is replaced by combination AFCI (CAFCI) or dual-function (AFCI/GFCI) breakers to meet updated electrical codes. Verify your local code requirements before installation.
