B-LINE 18186 HC NK – Frequently Asked Questions

1) Can a B-Line 18186 HC NK junction box be used outdoors or in a washdown area?
No. The 18186 HC NK is a NEMA Type 1 enclosure, which is indoor use only, for protection against incidental contact and falling dirt. It offers no rated protection against rain, hose-down, dust, or oil. For a wet or outdoor location you need a NEMA 3R or 4 enclosure instead.
2) What are the actual box dimensions of the B-Line 18186 HC NK enclosure?
It measures 18 inches high by 18 inches wide with a 6 inch depth, so you need an 18 by 18 inch clear wall area plus 6 inches of projection off the surface, and room for the hinged door to swing. It weighs 18 lb, light enough for a one-man mount into blocking or anchors.
3) Does this Eaton B-Line junction box come with knockouts already punched?
No knockouts. The NK in 18186 HC NK means no knockout, so the box ships blank and you punch your own conduit entries wherever the run needs them. Plan on a knockout punch set for the trade sizes you are landing.
4) How does the 18186 HC NK mount to a wall?
Surface mount, using thru holes in the back of the enclosure. There are no external mounting feet or flanges in that description, so your fasteners pass through the back panel into the wall, block, or strut behind it. Pick anchors rated for the 18 lb empty weight plus whatever gear and conductors you put inside.
5) Is the cover hinged or removable on this B-Line enclosure?
Both, in effect. The cover is hinged as a medium single door for routine access, and it is also removable when you need the opening clear to pull wire or set a backplate. It has a recessed pull ring and a friction dimple to hold it closed.
6) Does the B-Line 18186 HC NK have a lock or latch?
It closes with a friction dimple and a recessed pull ring, not a keyed lock or padlock hasp. That is fine for an electrical room or back-of-house space where access is already controlled, but if you need a secured enclosure in a tenant corridor or public area, specify a latching or lockable enclosure instead.
7) What gauge steel and finish is this junction box, and will it hold up in an unconditioned mechanical room?
The body is 16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard gear grey most switchgear and panel enclosures are supplied in. Painted carbon steel is suited to dry indoor spaces; in a damp or corrosive area you want stainless or a coated Type 4X enclosure.
8) Is this enclosure UL listed for a spec job?
Yes, the 18186 HC NK carries UL 50, the standard covering enclosures for electrical equipment. It is made in the US. If your drawing calls for a UL 50 Type 1 surface enclosure, this meets that call-out.
9) Is a 6 inch deep pull box enough for my conduit bends?
The 18186 HC NK gives 6 inches of interior depth behind an 18 by 18 inch opening. That is generous for splices and straight pulls, but for angle or U pulls the NEC sizes the box off conduit trade size, not the box depth, so check your largest raceway against those pull-box rules before you commit to 18 by 18.
10) What is the exact part number to order this Eaton B-Line box?
Order it as Eaton B-Line 18186 HC NK. The number reads as the dimensions and options: 18 inch height, 18 inch width, 6 inch depth, hinged cover, no knockouts.
