Product FAQs
5 answersWhat is the difference between the QB1025EP and a standard GFCI breaker?
The EP suffix in the catalog number stands for Equipment Protection. It features a 30mA ground fault trip threshold designed to protect machinery and heat tracing equipment, whereas standard GFCI breakers have a 5mA threshold for personnel safety.
Which panelboards accept the QB1025EP circuit breaker?
This BAB-frame breaker is designed exclusively for Eaton and Cutler-Hammer Pow-R-Line commercial panelboards. It requires a bolted connection directly to the panel busbar.
How does the ground fault sensing wire connect in the panel?
The breaker is equipped with a pigtail neutral wire. This pigtail must be routed and terminated directly to the neutral bus bar in the panelboard for the ground fault equipment protection to function properly.
What is the direct replacement for the legacy QBGFEP1025?
The QB1025EP is the current, direct replacement for the legacy Cutler-Hammer QBGFEP1025 catalog number. Both share the same physical dimensions, 30mA equipment protection rating, and bolt-on mounting.
What wire types and sizes are compatible with the load terminals?
The integrated box lugs accept either copper or aluminum wiring ranging from 14 AWG to 4 AWG. Ensure proper torque specifications are followed during installation.
