Can I mount a QOB3150VH branch breaker in an NQOD442L400CU panel?
Issue:
QOB3150VH Application assistance
Product Line:
Panelboards
Environment:
UL 67, UL 50, CSA C22.2 No.'s 20-M1989 & 94-M91, NEMA PB1, NFPA 70 Art. 408, Federal Specification W-P-115C Type 1 Class 1 , 2003 IBC, NFPA 5000, ASCE/SE17
Cause:
It may be desirable to mount a 150A branch device, a comparatively large device for the typical lighting panelboard application, in a 400A rated panelboard.
Resolution:
Yes, but note that it requires 6 pole spaces and that the maximum amperage breaker that can be mounted across from it is 20A. NOTE: NQOD panelboards are obsolete, superseded by NQ. This FAQ is applicable to NQ.
