B-LINE 18128 SCGV NK – Frequently Asked Questions
1) What size is the B-Line 18128 SCGV NK junction box?
The Eaton B-Line 18128 SCGV NK measures 18 inches high by 12 inches wide by 8 inches deep, and it weighs 15.5 lb. The 8 inch depth is generous for a box this size, so there's room to make up wire, land a terminal strip, or stack conductors without fighting the cover.
2) Can this Type 1 junction box be installed outdoors or in a wash-down area?
No. The 18128 SCGV NK is a NEMA Type 1 enclosure, which is indoor use only and provides a degree of protection against incidental contact with the enclosed equipment and falling dirt. It is not rated against rain, hose-down, dust, or oil. For an outdoor or wet location you need a Type 3R, 4, or 4X enclosure instead.
3) Does this Eaton B-Line box come with knockouts, or do I have to punch my own?
No knockouts. The NK in 18128 SCGV NK means no knockouts, so the box ships with blank walls and you drill or punch your own conduit entries exactly where the run lands. That is the usual choice on a make-up box when you don't want unused openings to seal off later. If you want factory knockouts, order the knockout version of the same size instead.
4) Does this junction box meet UL requirements for an electrical inspection?
The enclosure carries UL 50, the standard covering enclosures for electrical equipment, and it is a NEMA Type 1 rating. It is also made in the US, which matters if you're on a job with domestic sourcing requirements.
5) How does the cover attach, and can I get into the box after it's mounted?
The cover is a screw cover with plated screws, and it has keyhole slots so you can back the screws out part way and lift the cover off without removing them completely. Handy on an 18 x 12 cover you're taking off single-handed up a ladder.
6) How does this junction box mount to a wall?
Surface mount, through thru holes in the back of the enclosure. You anchor it straight to the wall, strut, or backboard with your own fasteners; mounting hardware and anchors are sized to your substrate and are not part of the box. At 15.5 lb empty, plus wire, anchor into structure or strut rather than drywall alone.
7) What is the 18128 SCGV NK made of, and does it need painting?
It's 16 gauge galvanized steel, supplied unfinished in its natural grey galvanized appearance rather than painted. The galvanized coating is the corrosion protection, so no paint is required for a normal dry indoor installation. If a job spec calls for a painted enclosure to match a panel line, you'd need to field-paint it or order a painted version.
8) Is a screw cover box like this the right choice, or should I use a hinged door enclosure?
A screw cover enclosure like the 18128 SCGV NK suits pull and junction points you open rarely: splices, make-up, terminal blocks, a feeder pull box. The cover comes fully off, which gives you unobstructed access to all four walls when you're pulling wire. If the box houses equipment someone opens routinely, a hinged door enclosure is the better call since the cover stays attached. Note this one is catalogued as a medium single door style body, still with a screw cover.
