Eaton BX3673PBS – Frequently Asked Questions

1) Does the Eaton NEMA 1 panelboard enclosure come with the panelboard interior and breakers?
No. This is the enclosure box only, the housing that the panelboard mounts into. The interior (bussing and mains), the trim or front, and the branch breakers are ordered separately and have to match the panelboard configuration you are building. Order the box to the interior, not the other way around.
2) Is a NEMA 1 enclosure like the Eaton BX3673PBS or a Square D Type 1 box the right choice for a damp or outdoor location?
No. The Eaton BX3673PBS carries a NEMA 1 rating, which covers general-purpose indoor use and protection against incidental contact with the enclosed equipment and falling dirt. The Square D MH Series NQ/NF enclosure is likewise a Type 1 box, so it is held to the same indoor, non-hazardous service conditions. Neither is intended for washdown areas, exterior walls, or wet locations; those openings call for a rainproof or watertight rated enclosure instead.
3) What is the Square D equivalent to the Eaton BX3673PBS panelboard enclosure?
The closest cross-brand counterpart is the Square D MH Series NQ/NF panelboard enclosure, a Type 1 steel box with a blank end wall. Both are general-purpose indoor enclosures: the Eaton BX3673PBS is a NEMA 1 panelboard enclosure built to house Eaton panelboards, while the MH Series box is sized and prepped for Square D NQ and NF interiors. Because panelboard boxes are matched to the manufacturer's interior mounting and gutter layout, pick the box that matches the brand of interior and trim you are installing rather than treating the two as drop-in substitutes.
4) Can I reuse an existing Square D MH Series box and just drop in an Eaton panelboard interior?
Treat that as a no without verification. The Square D MH Series box is an NQ/NF panelboard enclosure, dimensioned and prepped for those Square D interiors, while the Eaton BX3673PBS is built to house Eaton panelboards. Interior mounting studs, gutter space, and trim alignment are brand-specific, so a retrofit that keeps the old box generally means keeping the matching brand of interior. If you are changing brands, plan on the enclosure, interior, and trim from the same manufacturer.
5) How do I know which Eaton panelboard enclosure size to order?
Eaton offers this NEMA 1 enclosure in a range of box sizes so it can be matched to the panelboard footprint going into it. The enclosure is selected from the interior you are using, its width, height, and gutter space, plus the wall opening if it is a flush install. Confirm the interior catalog number first, then order the box that Eaton lists against it; BX3673PBS is one specific size in that family.
6) Is a NEMA 1 panelboard enclosure acceptable in a commercial electrical room?
Yes, that is the normal application. A general-purpose electrical room, an interior riser closet, or a back-of-house distribution wall are exactly where a NEMA 1 box belongs, in both new construction and retrofit work. The limit is environment, not building type: keep it out of damp, wet, dusty, or hazardous locations.
7) Can I reuse an existing panelboard box and just change the guts, or do I need a new enclosure?
You can reuse a box only if the replacement interior is the same manufacturer and lines up with the existing mounting and gutter space. Since this Eaton NEMA 1 enclosure is dimensioned to Eaton panelboard footprints, swapping an off-brand interior into it is not a supported combination. On a retrofit where the interior brand is changing, plan on a new box and front.
8) What does the blank end wall on the Square D MH Series box mean compared with the Eaton BX3673PBS enclosure?
The Square D MH Series NQ/NF enclosure is supplied with a blank end wall, meaning the end of the steel box comes without factory knockouts so the installer punches conduit entries where the run actually lands. The Eaton BX3673PBS is a NEMA 1 panelboard enclosure for indoor panelboard housing; confirm the conduit entry arrangement you need against the box you order, since a blank end wall requires field punching and the correct hole saw or knockout set on site.
