This bolt-on breaker is designed for use in Commander B/BC load centers, CEB load centers, and Sylvania bolt-on load centers.
Can the QBH1020GF be installed in standard plug-on panels?
No. This unit features a bolt-on mounting style. It physically bolts to the bus bar and cannot be installed in load centers designed for plug-on or snap-in breakers.
How is the neutral connected when installing this GFCI breaker?
The QBH1020GF includes a pigtail neutral wire. This coiled wire must be routed and terminated directly at the neutral bus bar in the panelboard to enable the ground fault detection circuitry.
What wire sizes are accepted by the terminal lugs on the QBH1020GF?
The box lugs on this breaker are rated to accommodate conductors ranging from 14 AWG up to 4 AWG.
What level of short circuit protection does the QBH series provide?
This model carries a 22kAIC interrupting rating at 120V. It is suitable for electrical systems where the available fault current exceeds standard 10kAIC limits, providing enhanced protection for commercial or high-capacity residential applications.
What specific protection functions does the QBH1020GF offer?
The breaker incorporates Long-Time, Instantaneous, and Ground-Fault (LIG) trip functions. It provides standard thermal-magnetic protection for overloads and short circuits, plus dedicated ground fault sensing to protect personnel from electric shock.
