Is it possible to order an NQ factory assembled panelboard furnished with (42) QOB120CAFI?
Issue:
NQ factory assembled panelboard furnished with (42) QOB120CAFI
Product Line:
PTFDS - Final Distribution Enclosure Systems
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:
Changes to requirements for arc fault protection of some circuits has resulted in greater need for CAFI branch breakers. In the past a large proportion of these circuit breakers in an NQ panelboard necessitated a double panel. This is no longer the case.
Resolution:
Yes, an engineering change now allows for (42) QOB120CAFI to be installed in a single section NQ panelboard.
The neutral pigtails of the branch breakers will be spliced as needed in order for the panelboard to accommodate all of the branch devices in a single section panelboard.
