NQ 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:
Specifications occasionally require 100% copper neutrals, often in combination with other 100% copper current carrying interior components.
Resolution:
Field installable 100% copper neutral kits are for NQ panelboards with 20 inch wide boxes only.
The neutral assemblies for NQ panelboards with 14 inch wide and column width enclosures are of a different design, and there is not a 100% copper neutral kit for them.
For the 100A rated interiors in 20 inch wide enclosures use 100% copper neutral kit NQN1CU.
For the 225A rated interior in 20 inch wide enclosures use 100% copper neutral kit NQN2CU.
For the 400A and 600A interiors, 100% copper neutral kit NQN6CU can be used, except in applications requiring 600A rated interiors equipped with sub-feed lugs, feed-thru lugs or sub-feed circuit breaker(s): for these specific applications, the NQN6CU is incompatible.
