B-LINE 18124 SCGV – Frequently Asked Questions
1) Can a NEMA 1 screw cover junction box like the B-Line 18124 SCGV be used outdoors or in a washdown area?
No. The 18124 SCGV carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It offers no protection against rain, hose-down, dust, or oil, so keep it out of wet locations, exterior walls, and food processing washdown zones. For those areas you need a gasketed NEMA 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions on the B-Line 18124 SCGV junction box?
It measures 18 inches high, 12 inches wide, and 4 inches deep. That 4 inch depth is what usually decides the job, since it sets how much room you have behind the screw cover for conduit bodies, splice bundles, and bend radius on larger conductors.
3) How many knockouts does the 18124 SCGV have and where are they?
Knockouts are provided on all four sides of the box: 9 on each side, 9 on top, and 9 on the bottom. That gives you a lot of freedom to run conduit in from whichever direction the raceway comes at the wall without having to punch fresh holes on site.
4) How does the 18124 SCGV mount to the wall?
It is a surface mount enclosure with thru holes in the back pan, so you fasten it directly to the wall or structure with your own anchors or bolts through those holes. Mounting hardware is not part of the enclosure, so pick fasteners to suit the substrate and the 11.4 lb box plus whatever wiring it will hold. It is not a flush or recessed box.
5) Is this a hinged door box or a screw-on cover?
The cover is a screw cover, not a hinged door, secured with plated screws. Keyhole slots on the cover let you hang it on the screws and then tighten, which is the difference between a one-man and a two-man cover install on an 11.4 lb box at ceiling height. If you need frequent access for troubleshooting, a hinged-cover enclosure is the easier choice.
6) Is the galvanized finish on this B-Line box paintable, or does it come painted?
The box is galvanized steel and listed as unfinished, grey in appearance, so there is no paint or powder coat on it from the factory. Galvanized is normally left bare in mechanical rooms, back-of-house, and plenum spaces. If the spec calls for a color-matched enclosure in a finished area, order a painted enclosure rather than trying to top-coat galvanizing.
7) What gauge steel is the B-Line 18124 SCGV junction box, and is it heavy enough for a commercial install?
Body wall thickness is 16 gauge galvanized steel. That is the usual commercial weight for a screw cover pull and junction box this size, stiff enough to carry conduit entries and terminal blocks without the sides oil-canning when you tighten locknuts.
8) Which exact part number do I order for the 18 x 12 x 4 B-Line screw cover box, and where is it made?
Order Eaton B-Line part number 18124 SCGV. The SCGV designation is the screw cover galvanized enclosure line, and this one is made in the US.
