Square D NQ84SP Main Breaker Panelboard is an indoor, NEMA 1–enclosed 84-space distribution panelboard rated for 250 A with a 208Y/120 V, 3‑phase, 4‑wire service. Part of Schneider Electric’s Square D NQ/NQM family, the NQ84SP accepts a main breaker kit (for example, JDP36250) and provides 84 spaces for branch‑circuit breakers, enabling scalable distribution for commercial or light industrial applications. This panelboard is designed for 208Y/120V 3‑phase service, UL listed, and its installation guidance is documented in Schneider Electric’s NQ/NQM panelboards materials (80043‑712‑06), with the unit intended for indoor use in a NEMA 1 enclosure. Use cases include feeders and subfeed distributions in new construction or renovations where a robust 250 A main and 84‑space capacity is required.
