B-LINE 18188 SCGV NK – Frequently Asked Questions
1) What size is the B-Line 18188 SCGV NK junction box?
The 18188 SCGV NK measures 18 inches high, 18 inches wide, and 8 inches deep, which is where the part number comes from. It weighs 20.6 lb, so plan on two hands or a helper when hanging it on a wall.
2) Can I mount this Eaton B-Line Type 1 junction box outdoors or in a washdown area?
No. It's a NEMA Type 1 enclosure, which is indoor-use only and gives protection against incidental contact with the enclosed equipment and falling dirt. It's not rated against rain, hose-down, dust, oil, or corrosive conditions. For outdoors or wet locations you need a Type 3R, 4, or 4X enclosure instead.
3) Does this B-Line junction box come with knockouts?
No. The NK in 18188 SCGV NK means no knockouts, so the box ships with solid walls and you punch or hole-saw your own conduit openings exactly where the run needs them. That is the usual choice on a custom or field-routed install; if you want factory knockout patterns you need the knockout version instead.
4) Is this junction box UL listed for a commercial electrical inspection?
Yes, the Eaton B-Line 18188 SCGV NK carries UL 50, the standard covering enclosures for electrical equipment. It is made in the US. Inspectors will also look at the Type 1 rating, which limits it to indoor, dry locations.
5) How does the cover come off on the 18188 SCGV NK, and can one person do it alone?
The cover is a screw cover with plated screws, and it has keyhole slots so once the screws are backed out part way the cover lifts and slides off without fully removing every screw. That is what makes an 18 x 18 cover manageable single-handed. No hinge, no latch, so plan for clearance in front of the box to pull the cover straight off.
6) How is this enclosure mounted to the wall?
Surface mount, through thru holes in the back of the box, so it fastens flat to a wall, backboard, or strut with your own hardware. It is not designed to recess into a wall cavity. At 20.6 lb empty, anchor into studs or a plywood backboard rather than drywall alone, and add for the weight of what you put inside it.
7) What is the 18188 SCGV NK box made of, and does it need painting?
16 gauge galvanized steel, supplied unfinished in a grey galvanized appearance. The galvanizing is the corrosion protection, so no paint is required for a dry indoor mechanical or electrical room. If you want it to match a painted panel line-up, you'd need to prep and coat it yourself, since no factory paint finish is applied.
8) Is this a hinged door enclosure?
No. It is catalogued as a medium single door style, but the closure is a removable screw cover, not a hinged and latched door. If the equipment inside needs frequent access, a hinged cover enclosure is the better fit; this one suits a box you open occasionally for pulls, splices, or service.
