Issue:

Do QOB-VH or QHB breakers will fit into the NQOB, QBL 330 Series T2 and 1W Panels?

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, 100A 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.
