NQOB panelboards and branch circuit breakers

Article available in these languages: Spanish

Issue:
What branch breakers does the obsolete NQOB panelboard accept?  Is there any mounting hardware required for them?

Product Line:
Obsolete NQOB Panelboards

Resolution:
NQOB panelboards accept QOB branch breakers, and a 60 A maximum branch circuit breaker can be installed into NQOB column width panelboard.  No mounting hardware is required for these.


Note: The QOB-VH and QHB breakers did not exist during the life of the NQOB interior and as a result were never UL/CSA tested or approved for use in the panel. They are not designed to be installed in the NQOB interior.
