Product FAQs
6 answersWhat panels are compatible with the Federal Pacific 2P125H circuit breaker?
This breaker is designed exclusively for use in legacy Federal Pacific (FPE) Stab-Lok load centers that accept plug-on breakers.
What does the H in the 2P125H catalog number indicate?
The H designates a high interrupting capacity. While the standard 2P125 model has a 10kAIC rating, the 2P125H is rated to safely interrupt up to 22kAIC at 240V.
What size wire do the load lugs on the 2P125H accept?
The load side lugs are designed to accept copper or aluminum conductors ranging from 1 AWG to 3/0 AWG.
How does the 2P125H connect to the panel bus?
It utilizes a plug-on connection specific to the FPE Stab-Lok bus design, snapping directly onto the bus bar without the need for bolt-on mounting hardware.
What safety checks are recommended when installing a replacement FPE Stab-Lok breaker?
Legacy Federal Pacific Stab-Lok panels have documented reliability issues. When installing a replacement breaker, a licensed electrician should thoroughly inspect the panel bus bars for pitting, arcing, or signs of overheating before seating the new breaker.
Are there modern aftermarket replacements available for the FPE 2P125H?
Yes, manufacturers like Connecticut Electric produce modern, ETL-listed aftermarket replacement breakers for Stab-Lok panels. If substituting the 2P125H, you must verify that the aftermarket replacement matches the 22kAIC high-interrupting rating required by your installation, as many standard replacements are only rated for 10kAIC.
