Product FAQs

5 answers
What load centers are compatible with the QA120AFCWG?

This breaker is designed exclusively for Siemens WireGuide load centers, including both PL and ES WireGuide series. It features a pre-trimmed neutral wire tailored specifically for the WireGuide neutral bar layout.

How does the WireGuide pigtail neutral simplify installation?

The QA120AFCWG features a pre-trimmed pigtail neutral that slides directly into the neutral bar as the breaker is seated. This eliminates the time-consuming step of routing and trimming standard pigtails. It also includes a small loop of extra wire in case adjustments are needed.

Can I install the QA120AFCWG in a standard Siemens load center?

No, the pre-trimmed neutral on the QA120AFCWG is too short for standard panel routing. It is built specifically for WireGuide load centers. For standard Siemens panels, you must use a standard pigtail AFCI or a Plug-On Neutral AFCI, depending on your panel design.

What is the difference between the QA120AFCWG, QA120AFCP, and QA120AFCN?

All three are 20A single-pole combination AFCI breakers. The QA120AFCWG features a pre-trimmed pigtail neutral designed exclusively for WireGuide load centers. The QA120AFCP features a standard, full-length pigtail neutral for traditional Siemens load centers. The QA120AFCN is a Plug-On Neutral breaker that eliminates the pigtail entirely for compatible PN and SN series panels.

What type of arc fault protection does this breaker provide?

As a Combination Arc Fault Circuit Interrupter (CAFCI), the QA120AFCWG detects both series and parallel arcing faults. This provides comprehensive protection against electrical fires and meets National Electrical Code (NEC) requirements for residential living areas.
