Description
NQ and NF Panelboards applications include commercial buildings, industrial buildings, data centers, stadiums, and offices. NQ and NF Panelboards are versatile panelboards that feature a wide selection of circuit breakers, accessories, and ready to install kits. These panelboards have many different options for your enclosure box and its accessories. This enclosure box is rated as a Type 1 with one blank end wall and one end wall with knockouts for common conduit sizes. The enclosure dimensions are 20 inch width x 44 inch height x 5.75 inch depth. NQ and NF enclosures are UL listed for use in the USA and Canada. The end walls of NF and NQ enclosures are removable to simplify field modification to support the widest range of electrical conduit connections. NC trim fronts for interiors rated up to 250A may be screwed directly to the deadfront of the NF or NQ panelboard. NC trim fronts for interiors rated 400A or greater are vented and designed to be screwed directly to the Type 1, 2 enclosure of the NF or NQ panelboard. MHxxWP enclosures provide Type 3R/5/12 protection to NF and NQ Panelboards, and are supplied with removable blank end walls. MHxxBE and MHxxD9 Type 1 enclosures are supplied with removable blank end walls at both ends. MHxx enclosures have one blank end wall and one end wall with knockouts for common conduit sizes.
Features
- Precision-engineered as a standard MH-type enclosure, this box is designed exclusively for 400A and 600A Square D NQ and NF panelboards. Utilizing the exact OEM enclosure prevents costly field modifications and ensures a seamless, professional fit for your interior, saving hours of labor during commercial electrical fit-outs.
- The 44"H x 20"W x 5.75"D dimensions provide an optimized internal volume that easily accommodates heavy-gauge copper or aluminum conductors. This spacious design prevents wire crowding and insulation damage, ensuring your industrial installation meets NEC wire-bending space requirements and maintains proper airflow for heat dissipation.
- Rated for NEMA Type 1 indoor protection, this heavy-duty steel housing shields your sensitive circuit breakers and busbars from dust, light, and accidental contact. It is the industry-standard choice for electrical rooms, data centers, and commercial basements where a robust, secure barrier is required to protect the building's core power distribution system.
- Fabricated from high-grade, galvanized steel with a phosphate-treated finish, this box is built to resist corrosion and physical impact during and after installation. The pre-punched knockouts and sturdy mounting holes allow for rapid, secure anchoring to masonry or stud walls, ensuring your electrical infrastructure remains stable and code-compliant for decades.
