B-LINE 30184 SC NK – Frequently Asked Questions
1) Can I use the Eaton B-Line 30184 SC NK junction box outdoors or in a washdown area?
No. The 30184 SC NK is a NEMA Type 1 enclosure, which is for indoor use only and provides protection against incidental contact with the enclosed equipment and falling dirt. It gives no protection against rain, hose-down, or dust ingress. For a wet or outdoor location you need a Type 3R or Type 4 enclosure instead.
2) What are the actual box dimensions on the B-Line 30184 SC NK enclosure?
It measures 24 inches high by 18 inches wide with a 4 inch depth, so the wiring gutter behind the cover is shallow. If you are pulling large conductors or stacking terminal blocks, check your bend radius against that 4 inch depth before committing.
3) Does the 30184 SC NK junction box come with knockouts for conduit?
No knockouts. The NK in the model designation means the box ships blank, so every conduit entry has to be punched or hole-sawed in the field where you want it. That is an advantage on a custom layout and extra labor if you expected pre-punched entries.
4) How is the Eaton B-Line 30184 SC NK mounted to the wall?
Surface mount, using thru holes in the back of the box. There is no flush or recessed trim provision, so you are fastening it flat to the wall or to a backing channel. At 27.8 pounds empty it needs solid anchoring, not drywall alone.
5) Is this a hinged door enclosure or a screw cover?
Screw cover. The 30184 SC NK uses a removable cover secured with plated screws, and the cover has keyhole slots so it hangs on the screws while you line it up single-handed. If you need a door you can swing open for routine access, pick a hinged cover enclosure instead of an SC type.
6) What gauge steel is the B-Line 30184 junction box, and will it match the other panels in my plant?
Body is 14 gauge carbon steel, painted ANSI 61 grey, which is the standard grey used across most industrial control enclosures, so it will blend with existing gear.
7) Is the B-Line 30184 SC NK enclosure UL listed, and where is it made?
It is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. That combination is what most government, healthcare and education specs are looking for on a junction box submittal.
8) What part number do I order for this B-Line screw cover junction box?
Order it as Eaton B-Line 30184 SC NK. The 30184 encodes the box size (24 by 18 by 4 inches), SC is the screw cover, and NK means no knockouts.
