Square D MHKE20 – Frequently Asked Questions
1) Will the Square D MHKE20 endwall kit fit an NF panelboard, or only NQ?
The MHKE20 blank endwall kit works on both NQ and NF panelboards. Both families share the same modular construction that accepts field installable accessories and conversion kits, so the endwall kit mounts to either. If your panel is a different Square D family (I-Line, for example), this is not the part.
2) What does a blank endwall kit with knockouts actually do on a panelboard?
It closes off the end of an NQ or NF panelboard enclosure, and the knockouts give you conduit entry points or room to add accessories later without cutting sheet metal on site. It is how you close out, extend, or reconfigure an existing enclosure instead of replacing the whole panelboard when a job changes.
3) I need to add conduit entries to an existing NQ panel. Is this the right accessory?
Yes, if the entry needs to be at the end of the enclosure. The MHKE20 is supplied with knockouts specifically so the endwall can be opened up in the field for accessory additions and modifications on an existing NQ or NF installation. It is meant for panelboard field modifications and retrofits, not new-panel-only use.
4) Can an ABB 200% neutral kit be used in place of the Square D MHKE20 endwall kit?
No. The MHKE20 is a blank endwall kit with knockouts, an enclosure closure piece for Square D NQ and NF panelboards. The ABB NKA8474 is a 200% neutral kit for Pro-Stock merchandise lighting panelboards, which is a neutral bus component rather than an enclosure endwall, and it is built for ABB panelboards. The two address different parts of a panelboard and are not interchangeable.
5) Does the MHKE20 endwall kit come assembled or do I have to build it in the field?
It ships factory assembled, so field work is mounting it rather than piecing it together. Square D lists it among the ready-to-assemble kits and accessories that let you make on-site design changes without a full panelboard replacement.
6) Is this a genuine Square D part or an aftermarket equivalent?
Genuine Square D, catalog number MHKE20, manufactured in Mexico. For an NQ or NF enclosure modification that matters, since the endwall has to land on the factory mounting provisions of the panelboard.
7) Will an ABB panelboard kit work as a substitute for the Square D MHKE20?
No. The ABB accessories we carry serve different functions and different panel families: the ABB A Series circuit numbering strip is for PNBD panelboards, and the ABB NKA8474 is a 200 percent neutral kit for Pro-Stock merchandise lighting panelboards. Neither is an endwall closure, and neither mounts to an NQ or NF enclosure. Endwall hardware has to match the panelboard family it bolts to.
8) I need to label the circuits in my panel, not close out the end of the box. Is the MHKE20 the right part?
No. The MHKE20 is a blank endwall kit supplied with knockouts, used to close out, extend, or reconfigure an NQ or NF panelboard enclosure. For circuit identification, the part you want is a circuit numbering strip, such as the ABB 569B806G A Series circuit numbering strip for PNBD panelboards. Those are separate functions and the endwall kit does no labeling.
9) Do I have to replace the whole panelboard, or can I add an accessory kit to what is installed?
NQ and NF panelboards use a modular construction that accepts field installable accessories and conversion kits, and the Square D MHKE20 blank endwall kit is factory assembled so it can be added to an existing enclosure without replacing the unit. Accessory kits from other lines, such as the ABB NKA8474 neutral kit, are built for ABB panelboards rather than the NQ and NF platform, so match the accessory to the panelboard brand and series already in the wall.
10) Does the Square D MHKE20 endwall kit meet RoHS and mercury-free purchasing requirements?
It is RoHS EU compliant, mercury free, and toxic heavy metal free. That covers the usual sustainable-procurement screens institutional and government buyers run on electrical gear.
11) How many versions of the MHKE20 endwall kit are there?
One. MHKE20 is a single catalog number with no finish, size, or configuration options to pick from, so there is nothing to specify beyond the part number when you order.
