Product FAQs
5 answersWhich load centers and metering equipment are compatible with the QOM2150MM?
This QOM2 frame main breaker is designed for use in Square D QO and Homeline convertible load centers, as well as MP Meter-Pak meter centers that accept 150A main breakers.
What is the difference between the QOM2150MM and the QOM2150VH?
The primary difference is the interrupting rating. The QOM2150MM is rated for 10kAIC at 120/240VAC, while the QOM2150VH is rated for 22kAIC. Both share the same physical QOM2 frame size and 150A rating.
What is the recommended lug torque for the QOM2150MM main breaker?
The main wire lugs should be torqued to 250 lb-in for 4 AWG to 300 kcmil aluminum or copper conductors. Always verify the exact torque specifications printed on the breaker label before installation.
Does the QOM2150MM require a specific mounting hardware kit?
No additional hardware kit is required. This bolt-on main breaker installs directly onto the busbar of compatible QO or Homeline load centers using the mounting screws provided with the breaker.
Does the QOM2150MM feature a Visi-Trip indicator?
Yes, like many Square D breakers, it includes a Visi-Trip indicator. When the breaker trips due to an overcurrent or short-circuit condition, the handle snaps to a center position and a highly visible red indicator appears, allowing for quick identification of the tripped circuit.
