B-LINE 10104 HC – Frequently Asked Questions
1) Can the Eaton B-Line 10104 HC junction box be used outdoors or in a washdown area?
No. The 10104 HC is a NEMA Type 1 enclosure, which covers indoor use only, protecting against dust and incidental contact. It gives no protection against rain, hose-down, or corrosive atmospheres. For a wet exterior wall or a washdown bay you need a Type 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions on the B-Line 10104 HC enclosure?
It measures 10 inches high, 10 inches wide, and 4 inches deep. The 4 inch depth is the number to watch if you are landing large conductors or a terminal strip inside, since bending space eats that dimension fast.
3) Is the cover on this B-Line junction box hinged or do I have to unscrew it every time?
Hinged, and it is also removable. It has a recessed pull ring and a friction dimple, so it stays shut but opens by hand for inspection without chasing loose screws on a ladder. That is the practical reason to pick the HC version over a screw-cover box in a panel you open often.
4) Is the 10104 HC enclosure UL listed for an institutional spec job?
It carries UL 50, the standard covering enclosures for electrical equipment, and it is a NEMA Type 1 indoor enclosure. Country of origin is the US. Those are the three lines a spec reviewer or MRO buyer usually wants on the submittal.
5) How many knockouts does the B-Line 10104 HC come with and where are they?
Five knockouts on the top, five on the bottom, and five on the sides. That layout lets you bring conduit in and out on multiple faces without punching the box, useful when you are pulling a pull box or gutter into an existing run.
6) How does the B-Line 10104 HC mount to the wall?
Surface mount, with thru holes in the back of the box. You fasten straight through to the substrate, so no mounting feet or brackets are involved, and fasteners are not part of the box. It is not designed for flush or recessed installation in a wall cavity.
7) What is this junction box made of and what gauge is the steel?
Carbon steel at 16 gauge wall thickness, painted ANSI 61 grey. That gauge is what keeps a 10 x 10 box from oil-canning when you tighten connectors into it. Painted carbon steel suits dry indoor mechanical rooms and electrical closets; in a damp or chemical environment, go stainless or non-metallic.
8) Will the ANSI 61 grey finish match the other Eaton B-Line enclosures already in my electrical room?
Yes, ANSI 61 grey is the standard grey used across industrial enclosures and panelboards, so a wall of grey boxes will read as one set. The 10104 HC ships painted in that color, no field finishing required.
9) How heavy is the B-Line 10104 HC, and is it a one-person install?
6.5 lb empty. A single installer can hold it to the wall and drive fasteners through the back thru holes without help, though anchoring into drywall rather than a stud or strut is still a bad idea once conduit and conductors add load.
