Description
Features
- Engineered with a premium, solid copper busbar, this lighting and distribution panelboard interior delivers maximum electrical efficiency and significantly lower heat dissipation than aluminum alternatives. For facility managers and commercial electricians, this ensures minimized voltage drops, maximum joint integrity, and cool continuous operations in demanding 240V AC or 48V DC applications.
- Providing 18 available pole spaces in a standard 3-phase, 4-wire layout, this 100 Amp interior allows for precise, balanced phase loading across commercial distribution systems. The chassis accepts both QO plug-on and QOB bolt-on branch circuit breakers (including standard, high-interrupting QOB-VH, and QHB series), giving contractors the flexibility to lock down breaker attachments based on site-specific vibration or building specs.
- Purpose-built to drop directly into standard 20-inch wide Square D NEMA enclosures with a height of 26 inches and a nominal depth of 5.75 inches, this interior offers a perfect factory fit. The streamlined dimensions maximize gutter space for clean, compliant wire-bending loops, helping field crews wrap up complex commercial routing tasks quickly and neatly.
- The main connection block is equipped with high-grade lugs that safely secure aluminum and neutral conductors ranging from AWG 6 up to AWG 2/0. Tightening the terminal screws to the factory-certified torque profile of 40.01 to 50 lbf-in (4.52 to 5.65 N-m) ensures a compression bond that resists natural thermal expansion cycles, preventing arcing and localized degradation at the main feed drop.
- This NQ series interior supports short-circuit current ratings (SCCR) up to a maximum of 65 kA, varying dynamically based on the interrupting thresholds of the specific branch breakers installed. Carrying complete UL and CSA safety certifications, this rugged distribution interior ensures hassle-free compliance with national and provincial electrical codes during final building inspections.
