Footnotes

  1. DC voltage applications require installation of DC rated QO(B) circuit breakers
  2. Please note that some local building codes limit panelboards to 42 circuits, including those that reference 2005 or earlier version of NFPA 70.
  3. Accepts all QO(B) shown in Tables in Sections 7 and 9. Branch circuit breaker trip ampacity cannot exceed panelboard mains rating. 175 A and 200 A circuit breakers may only be installed in single phase 400 A and 600 A NQ Panelboards. Tandem circuit breakers may not be installed.
  4. “C” suffix indicates copper bussing.
  5. Enclosure height may increase if accessories including alternate neutral lugs, condo riser neutral assemblies, feed-thru lugs, or sub-feed lugs are installed. 26 in. wide enclosures and trim fronts are required if condo riser neutral assemblies are installed.
  6. Wall mounting brackets add 0.4 inches to back of MHxxWP enclosures.
  7. Nominal interior dimensions, see PBA600 for details.
  8. D9 suffix indicates the 8.75 in. Deep Enclosure required for panelboards wit PowerPacT L Main Breaker, Switch, or Sub-Feed Breaker. See PBA604 for dimensional details.
  9. If Blank End Walls are desired at both ends of NEMA 1 Enclosure, select catalog number with “BE” suffix.
  10. Add “F” for flush mount, “S” for surface mount.
  11. Three point latch trim fronts are required for enclosures on panelboards with QO2175, QO2200, QO2175VH, or QO2200VH branch circuit breakers. These breakers take four pole spaces in single phase NQ interior.
  12. Enclosure includes trim kit. Nominal interior dimensions, see PBA711 for details.
  13. Vented Type 3R enclosure with three point latch door. Required for outdoor applications with two sub-feed breakers, or sub-feed breaker with trip current >150A. NEMA 3R enclosures must be bottom fed, and a NQ12RDE kit should also be selected. Interior nominal dimensions, see PBA603WP for details.
  14. For the NQ14-inch-wide panelboard offer, See NQ 14-inch-wide—240 Vac, 48 Vdc.
  15. Use only if the Local Jurisdiction where this panelboard interior is being applied has adopted the 2008 NFPA 70—National Electrical Code® (NEC®), which allows single panelboard interiors greater than 42 circuits.
  16. NEMA 3R, 5, or 12 enclosures must be bottom fed, when selected, an NQ12RDE kit should also be selected. See NQ Merchandised Accessories.
  17. NEMA 3R, 5, or 12 enclosures must be bottom fed, when selected, an NQ12RDE kit should also be selected. See NQ Merchandised Accessories..
