Product FAQs
5 answersCan I install the FAL12015 in a standard QO or Homeline load center?
No. The FAL12015 is an F-Frame molded case circuit breaker designed for commercial Square D enclosures, switchboards, and panelboards. It is not interchangeable with residential QO or Homeline plug-on breakers.
Is the Square D FAL12015 still in active production?
The FAL12015 belongs to the legacy F-Frame series, which has been superseded by the modern Square D PowerPact B-Frame series for new installations. However, F-Frame breakers are still widely sourced for direct replacements in existing panels.
Does the FAL12015 require special terminals for aluminum wiring?
No. The factory-installed feed-thru lugs are dual-rated for both copper and aluminum conductors. They accept 14 to 4 AWG copper or 12 to 4 AWG aluminum wire without requiring separate adapters.
What does the LI trip function code mean on the FAL12015?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time (L) protection for sustained overloads and Instantaneous (I) protection for short circuits. Both the thermal and magnetic trip points are fixed on this model.
How does the FAL12015 mount into a panel?
This is a unit mount circuit breaker. It uses a feed-thru connection with line and load lugs, meaning it is individually mounted to a backpan and wired directly, rather than plugging directly onto a busbar like an I-Line breaker.
