Issue:
What is the difference between a QO and QOB breaker?

Product Line:
QO and QOB

Resolution:
A QO breaker is plug on mounting and can be used in QO load centers, old NQO and NQOD panelboards, and current NQ panelboards. A QOB breaker uses a bolt on connection to the bus and can be used in old NQOB and NQOD panelboards and current NQ panelboards. Otherwise the breakers are the same.
