Product FAQs
6 answersWhich electrical panels are compatible with the QBH1030GF circuit breaker?
This bolt-on breaker is designed to fit classic Commander B/BC, CEB, and Sylvania bolt-on load centers. It features a 3/4-inch form factor specific to these vintage panel designs.
Can I use the QBH1030GF to replace an older QBHGFT1030 breaker?
Yes, the QBH1030GF serves as a direct replacement for the legacy Eaton and Cutler-Hammer QBHGFT1030 model. It provides the same 30A rating, 22kAIC interrupting capacity, and bolt-on mounting.
What is the ground fault trip sensitivity of this breaker?
The QBH1030GF features a 5mA trip sensitivity. This Class A GFCI rating is designed for personnel protection, rapidly interrupting power to reduce the risk of electrical shock if a ground fault is detected.
How is the neutral wire connected on the QBH1030GF?
This breaker includes a pigtail neutral wire. During installation, the pigtail must be securely connected directly to the neutral bus bar in the load center to ensure the ground fault protection functions correctly.
What are the recommended terminal torque values for wiring this breaker?
For Eaton Quicklag miniature breakers, the recommended torque depends on the wire gauge. Use 20 in-lbs for 14 to 10 AWG, 25 in-lbs for 8 AWG, and 27 in-lbs for 6 to 4 AWG wire. Always verify the exact torque specifications printed on the side of the breaker before finalizing connections.
Does this breaker provide both thermal and magnetic trip protection?
Yes, it utilizes thermal-magnetic trip technology. The thermal element provides long-time protection against gradual overloads, while the magnetic element offers instantaneous protection against severe short circuits.
