Square D NC26F – Frequently Asked Questions

1) What size panelboard enclosure does the Square D NC26F flush cover fit?
The NC26F cover measures 26 inches by 20 inches, so it is sized for an NQ or NF enclosure box with that same 26 x 20 inch opening. Square D covers are box-specific, not universal, so measure the existing box height and width before ordering. If your box is a different height, you need the matching NC cover for that size instead.
2) Is the Square D NC26F a flush cover or a surface mount cover?
Flush mount. The NC26F sits against the wall surface for a low-profile finish, which is what you want when the NQ or NF box is recessed into a finished wall. For a box mounted on the face of the wall you need a surface-style front, not this one.
3) Can I use the NC26F cover on a 225A or 400A Square D panelboard?
No. The NC26F is matched to NQ/NF panelboard systems with a 125A line rated current. Higher-ampere NQ/NF assemblies use larger boxes and different front sizes, so the cover will not line up.
4) Is the Square D NQ/NF flush cover UL listed for a commercial inspection?
It is cULus listed, which covers both US and Canadian requirements, and the cover is Type 1 construction for indoor dry locations. Type 1 is not rated for washdown, outdoor, or dusty areas; the NQ/NF platform is also offered in NEMA Type 2, 3R, 4, 4X, 5 and 12 enclosures for those environments.
5) If the panelboard box is surface mounted rather than recessed, is the Square D NC26F cover still the right choice?
No. The NC26F is a flush mount cover, sized 26 in high by 20 in wide, so it is intended to sit against the wall surface over a recessed box. For a surface mounted box, the ABB AF A-Series surface mount panelboard front cover is built for that mounting arrangement instead. Match the cover mounting style to how the enclosure box itself was set in the wall.
6) What is the closest flush panelboard front to the Square D NC26F from another manufacturer?
The ABB AF-F is an AF Series RLP unassembled flush panelboard front, which is the same flush front concept. The difference in practice is that the NC26F is a steel cover matched to Square D NQ and NF enclosure boxes and ships as a finished gray cover, while the AF-F is supplied unassembled for the ABB RLP platform. Panelboard fronts are not interchangeable across manufacturers, so the box line decides the cover.
7) What torque should the NQ/NF panel cover screws be tightened to?
10 to 12 lb-in on the cover fasteners. Going past that can distort a flush steel front or strip the fastening points, and under-tightening leaves the trim sitting off the wall line.
8) I need a surface mount panelboard front instead of flush. What are my options?
The NC26F is flush only. If your box is surface mounted, look at a surface-style front for your panel brand, for example the ABB AF A-Series surface mount panelboard front cover for ABB A-Series panels. For a Square D NQ/NF box, order the surface version of the NC front in your box size rather than this flush one.
9) Does the NC26F include the panelboard box or interior?
No. The NC26F is the front cover and trim only. The enclosure box, the panelboard interior, breakers, and the directory card are all separate orders; this part is what you buy when the existing front is damaged, missing, or you are converting a job to a flush finish.
10) Is the Eaton P475810 sub-feed breaker cover an alternative to the Square D NC26F?
No. The Eaton P475810 is a Pow-R-Xpress sub-feed breaker cover for a 600A panel bottom, meaning it closes off a sub-feed breaker area within that panel rather than serving as the full panelboard front. The NC26F is the Type 1 flush enclosure cover for an NQ or NF box on a system with a 125A line rated current. They solve different openings and do not substitute for each other.
11) We standardize on ABB RLP panels in some buildings - what cover goes there instead of the Square D NC26F?
For ABB RLP panels, the ABB AF-55FD RLP Series panelboard front trim cover is the front built for that series. The NC26F is matched to Square D NQ and NF enclosure boxes and is cULus listed as a Type 1 flush steel cover. If a facility runs both platforms, keep the covers specified by panel line rather than by size alone, since the front mounts to the box hardware pattern.
