Are the installation requirements the same for QO2150, QO2150VH, and QOB2150VH circuit breakers in single phase NQ Panelboards?

Issue:
Installation requirements for QO and QOB-VH breakers in single phase NQ Panelboards.

Product Line:
NQ Panelboard

Environment:
Application

Resolution:
Not exactly.  QO2150 and QO2150VH circuit breakers require the same installation restrictions as QO2175, QO2200, QO2175VH, and QO2200VH branch circuit breakers. QOB2150VH circuit breakers are slightly different in construction and do not require three-point latch trim fronts.  NQ Panelboard applications for all these circuit breakers are limited to single phase 400A and 600A interiors.
