Square D NQ Blank Endwall Kit, Panelboard Accessory
The Square D NQ blank endwall kit is a field-installable accessory engineered for NQ and NF panelboards, which feature modular construction to accept a wide range of circuit breakers, accessories, and ready-to-install kits. This blank endwall kit closes out an open end of the panelboard enclosure, giving contractors and end users a clean, factory-matched finish when a panelboard is not fully populated or is being reconfigured on site. As part of the broader NQ/NF accessory and replacement-parts lineup, it supports the same modular design philosophy that lets these panelboards be adapted, expanded, or modified well after initial installation.
Key Features
- Wide Accessory Selection: NQ and NF offer a wide selection of accessories and replacement parts, supporting long-term serviceability of the panelboard system.
- Factory-Assembled Design: Factory assembled options allow design flexibility and maximize job productivity for panel installers.
- Ready-to-Assemble Kits: Ready to assemble kits and accessories support on-site design changes without custom fabrication.
- Modular Flexibility: Easy to modify or extend the use of the panelboard as load requirements or layouts change.
- Panelboard Compatibility: Designed specifically for NQ and NF panelboard endwall closures within Square D's modular enclosure accessory line.

Why Square D?
Square D builds NQ and NF panelboards around a modular platform so that endwall kits, breakers, and conversion accessories can be added or swapped without replacing the entire enclosure. Factory-assembled, ready-to-install components like this blank endwall kit help contractors and end users maintain a finished, code-compliant appearance while keeping panelboard systems flexible for future changes. That combination of modularity and factory quality control is what makes Square D panelboard accessories a practical choice for commercial electrical work.

Square D MHBE20 – Frequently Asked Questions
1) What does the Square D MHBE20 blank endwall kit actually do on a panelboard?
The MHBE20 is a blank endwall kit that closes out an open end of an NQ or NF panelboard enclosure. You use it when the panel isn't fully populated or is being reconfigured in the field, so the end of the box has a factory-matched, finished closure instead of an open gap. It ships factory assembled and installs in the field with no custom sheet metal work.
2) Can I add an endwall kit to a panelboard that's already installed, or do I have to swap the whole enclosure?
You can add it to an existing panel. Square D builds NQ and NF around a modular platform so endwall kits, breakers, and conversion accessories can be added or swapped without replacing the enclosure. That's the point of this part: it's a ready-to-install component for reconfiguration and renovation work on boards that are already in service.
3) Can an ABB A Series circuit numbering strip be used instead of the Square D MHBE20 endwall kit?
No, they do different jobs. The MHBE20 is a blank endwall kit that closes out an open end of an NQ or NF panelboard enclosure, giving a factory-matched finish when the panel is not fully populated or is being reconfigured. The ABB 569B806G is a circuit numbering strip for A Series PNBD panelboards, which labels circuit positions rather than closing an enclosure opening. If you need the end of an NQ or NF panelboard interior closed off, the MHBE20 is the part; a numbering strip will not fill that opening.
4) Does the Square D blank endwall kit meet RoHS and heavy-metal restrictions for our spec?
It's listed as RoHS EUR compliant, mercury free, and toxic heavy metal free, with a WEEE product category of 4. Recycled metal content at Cr level is 0 percent. Those are the environmental declarations Square D publishes for the part, which covers most institutional submittal checklists.
5) Is a blank endwall kit the same thing as a neutral kit or a circuit numbering strip?
No, and they solve different problems. The MHBE20 is sheet-metal closure for the end of the enclosure. If what you need is extra neutral capacity for harmonic loads, that's a neutral kit, such as the ABB NKA8474 200% neutral kit for Pro-Stock lighting panelboards. If you need to label circuits, that's a numbering strip, like the ABB A Series circuit numbering strip for PNBD panelboards. None of those three substitute for each other.
6) I need to add neutral capacity to a lighting panel, not close an end wall. Is the MHBE20 the right part?
No. The Square D MHBE20 is a blank endwall kit for NQ and NF panelboards and only serves to close an open end of the enclosure. For added neutral capacity on a lighting panelboard, the comparable part is the ABB NKA8474 200% neutral kit for Pro-Stock merchandise lighting panelboards. Note that these are different manufacturers' platforms, so confirm your panelboard brand and series before ordering either.
7) Are Square D NQ panelboard accessories interchangeable with ABB panelboard accessories?
No. The MHBE20 endwall kit is engineered specifically for Square D NQ and NF panelboards and their modular enclosure accessory line. ABB accessories such as the 569B806G numbering strip are built for ABB A Series PNBD panelboards, and the NKA8474 neutral kit for ABB Pro-Stock merchandise lighting panelboards. Each manufacturer's enclosure interiors and mounting provisions are specific to its own platform, so match the accessory to the panelboard series stamped on the panel label.
8) Is the Square D MHBE20 endwall kit meant for commercial work or residential?
Commercial. The market segmentation on the MHBE20 is commercial, and NQ/NF panelboards are the commercial distribution boards in Square D's lineup. Typical uses are new construction, renovation electrical work, and endwall closure on panels being reconfigured.
9) What is the part number and where is the Square D endwall kit made?
Order it as Square D MHBE20. Country of origin is Mexico, which is the detail most often asked for on government and institutional submittals.
