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 26 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

Engineered for ultimate job-site flexibility, the MH26 enclosure box seamlessly accommodates both NQ (240VAC) and NF (480Y/277VAC) lighting and appliance panelboard interiors. This universal design eliminates ordering confusion and allows commercial electrical contractors to standardize their indoor distribution hardware across varying voltage requirements.
Measuring 26 inches high, 20 inches wide, and 5.75 inches deep, this housing provides code-compliant, generous wire-bending space and gutter room. The optimized layout ensures industrial electricians can cleanly route high-gauge feeders and branch circuit wiring without crimping cables, dramatically speeding up terminal connections and troubleshooting.
Featuring one pre-punched end wall with common conduit size knockouts and one blank end wall, this enclosure adapts smoothly to any top- or bottom-fed incoming service. The end walls are completely removable, allowing you to quickly punch custom entries or make field modifications on the fly without compromising the structural integrity of the main box.
Constructed from premium, hot-dipped galvanized sheet steel, the MH26 provides exceptional structural rigidity and corrosion resistance. Built to withstand physical impacts and accidental tool strikes during the rough-in phase, it safeguards sensitive internal electrical components from structural warping and workplace debris.
