Product FAQs

6 answers
Can I use the QOM125VH in both QO and Homeline load centers?

Yes, this main breaker is compatible with both Square D QO and Homeline load centers that are designed to accept a QOM1 frame main breaker.

What is the difference between QOM1 and QOM2 frame main breakers?

The QOM1 frame is physically smaller and supports 50A to 125A ratings, while the QOM2 frame is larger and supports 100A to 225A ratings. They are not interchangeable, so you must verify which frame size your panel requires.

What does the VH stand for in the QOM125VH catalog number?

The VH suffix indicates a higher interrupting rating of 22,000 AIC at 120/240VAC. The standard QOM125 without the VH suffix has a 10,000 AIC rating.

What is the recommended tightening torque for the lugs on the QOM125VH?

The factory recommended tightening torque for the box lugs is 53.1 lb-in when terminating aluminum or copper conductors within the accepted 4 AWG to 2/0 AWG range.

How does this main breaker mount inside the load center?

The QOM125VH features a bolt-on connection. It secures directly to the load center bus using a captive interior mounting screw, which allows for straight-in wiring from the service entrance.

Can the QOM125VH be used as a back-fed main breaker?

No. QOM1 frame breakers are dedicated main breakers designed to bolt directly to the main bus area of the load center. They cannot be installed on the branch circuit bus as a back-fed main.

    Works great as designed

    Needed this specific breaker for a drop-in replacement and this was it. I wasn’t disappointed. Superbreakers had it when others didn’t.
