B-LINE 18188 SC – Frequently Asked Questions

1) Can the Eaton B-Line 18188 SC junction box be used outdoors or in a wet location?
No. The 18188 SC is a NEMA Type 1 enclosure, which is indoor-only protection against incidental contact and falling dirt. It has no gasket and no rating for rain, washdown, or dust. For an exterior wall, a loading dock, or any damp location you need a Type 3R or Type 4 enclosure instead.
2) What are the actual box dimensions on the B-Line 18188 SC screw cover enclosure?
It measures 18 inches high, 18 inches wide and 8 inches deep, so it is a square-faced box with a deep back box for wire bending room and gutter space. Weight is 20.1 lb, which is a two-hand lift onto the wall but a single-person install with anchors pre-set.
3) Does this B-Line junction box come with conduit knockouts already punched?
Yes. The 18188 SC has 9 knockouts on each side, 9 on the top and 9 on the bottom, so you can bring conduit in from four directions without drilling or punching in the field. Thru holes in the back are provided for mounting.
4) Screw cover or hinged door junction box, which should I spec?
The 18188 SC is a screw cover box. The cover lifts off entirely on plated screws, with keyhole slots so you can back the screws out part way and drop the cover over them during install without juggling it. That suits a pull box or splice point you rarely open. If the enclosure will be opened routinely for testing or terminations, a hinged door version is easier to live with, because a loose screw cover has to be set down somewhere every time.
5) How does the 18188 SC mount, and does it need a backplate or strut?
It is a surface mount enclosure with thru holes in the back for lagging or bolting directly to a wall or to strut. Fasteners are not part of the box, so pick anchors rated for the 20.1 lb empty weight plus your conduit and conductor load. No back panel is included with a screw cover junction box of this style; if you need to mount devices inside, order a panel separately.
6) What is the 18188 SC junction box made of and how is it finished?
Carbon steel at 16 gauge, painted ANSI 61 grey. That is the standard grey used on most commercial switchgear and panelboards, so it matches the rest of the electrical room rather than standing out. Being painted steel it is fine for dry interior use; in corrosive or washdown areas look at a stainless or non-metallic enclosure.
7) What part number do I order to match an existing B-Line 18 x 18 x 8 screw cover box?
The manufacturer part number is 18188 SC, an Eaton B-Line series Type 1 screw cover enclosure. The number reads as the dimensions: 18 high, 18 wide, 8 deep, with SC for screw cover. If you are standardizing a building on one box size, that number is what the spec and the reorder should show.
