B-LINE 10104 HC NK – Frequently Asked Questions

1) Can a NEMA 1 junction box like the Eaton B-Line 10104 HC NK be used outdoors or in a wet area?
No. The 10104 HC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It has no gasket rating for water, dust, oil, or washdown, so keep it out of wet locations, exterior walls, and any area subject to hose-down. Indoor mechanical rooms, electrical closets, and dry plant walls are where it belongs.
2) What are the actual box dimensions of the Eaton B-Line 10104 HC NK junction box?
It measures 10 inches high, 10 inches wide, and 4 inches deep, and weighs 6.5 lb. That 4 inch depth is the number to check before you order: it gives you room for splices and small terminal blocks, but a deep contactor or a panel-mounted device may need a deeper enclosure.
3) Does the 10104 HC NK enclosure come with knockouts, or do I have to punch my own conduit holes?
No knockouts. The NK in the model designation means the box ships blank, so every conduit entry is field-punched where you want it. Plan on a knockout punch or hole saw sized to your conduit. The only factory holes are the mounting thru holes in the back.
4) How does the hinged cover on this B-Line junction box work, and can it be taken off completely?
The cover is hinged for one-handed access, and it is also removable, which helps when you are pulling wire or mounting a sub-panel inside. It uses a recessed pull ring and a friction dimple to stay shut rather than a latch or lock, so if you need a locking enclosure this is not the one.
5) How is this 10x10x4 junction box mounted to the wall?
Surface mount, using thru holes in the back of the box. You fasten straight to the wall or to Unistrut with your own hardware, sized to the substrate; fasteners are not part of the box. At 6.5 lb empty it is light enough for most anchors, but count the weight of the conductors and any devices you add inside.
6) What gauge steel is the Eaton B-Line HC NK junction box, and what is the finish?
Body and cover are carbon steel at 16 gauge, painted in ANSI 61 grey, the standard grey used across most industrial control and electrical gear so it blends with existing panels. Since it is painted steel with no corrosion rating claimed, keep it in dry indoor locations.
7) Is the 10104 HC NK a single-door enclosure, and what is the correct part number to order?
Yes, it is a small single door style box. Order it as Eaton B-Line model 10104 HC NK. The first digits describe the size: 10 high by 10 wide by 4 deep, HC for hinged cover, NK for no knockouts.
8) Is this junction box made in the USA?
Country of origin is the United States. That matters if you are bidding public work with domestic-sourcing language in the spec.
