Can a QOB-VH or QHB breaker be used in an NQOB panel?
Product Line:
Obsolete NQOB Panelboards
Resolution:
The NQOB panelboard originally took a Q1B branch breaker and was replaced by NQ with QO/QOB branch breaker.
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.
Additionally, 100 A QOB breakers are the maximum branch breakers that can be added to an NQOB panelboard. If not already installed, an SK5668 branch connector kit will also be required.
