B-LINE 181810 SC – Frequently Asked Questions

1) Can the Eaton B-Line 181810 SC junction box be used outdoors or in a washdown area?
No. The 181810 SC carries a NEMA Type 1 rating, which is indoor, general purpose only. It offers no protection against rain, hose-down, dust or corrosive atmospheres. For an outdoor wall, a mechanical room with water exposure, or a food-service washdown area you need a Type 3R or Type 4/4X enclosure instead. It is UL 50 listed as an enclosure.
2) What are the actual box dimensions on the B-Line 181810 SC screw cover enclosure?
It measures 18 inches high by 18 inches wide with a 10 inch depth, so plan for a 10 inch projection off the wall plus room to pull the cover straight off. Shipping/handling weight is 22.8 lb, which is a one-man lift but heavy enough that you want the mounting anchors set before you offer it up.
3) How does the cover come off, and will I need tools to get back into the box?
The 181810 SC uses a screw-on cover, not a hinged door, so it comes off completely with a screwdriver. The cover has keyhole slots so you can back the plated screws out part way and lift the cover off without removing them entirely, which keeps you from dropping hardware into a live gutter. If you need frequent access without loose covers, specify a hinged-cover enclosure instead.
4) Does this B-Line junction box come with knockouts already, or do I have to punch my own conduit holes?
Knockouts are provided: 9 on the sides, 9 on the top, and 9 on the bottom of this 18 x 18 x 10 enclosure. That gives you feed and branch entries on three faces without punching steel in the field. If your conduit run doesn't land on a knockout, the 16 gauge carbon steel body takes a standard hole saw or knockout punch.
5) What part number do I order for the Eaton B-Line 18 x 18 x 10 screw cover Type 1 box?
The manufacturer part number is 181810 SC. The number reads directly as the dimensions, 18 high by 18 wide by 10 deep, with SC for screw cover. Same family as the hinged-cover B-Line enclosures, so if you want a door instead of a screw-on lid you order a different suffix in the same size.
6) Will this B-Line box match the grey gear already in my electrical room?
It ships painted in ANSI 61 grey, the standard light grey used on most switchgear, panelboards and control enclosures, so it lines up visually with typical existing equipment. Body and cover are carbon steel under the paint.
7) Is 16 gauge steel heavy enough for a wiring gutter or pull box in a commercial building?
16 gauge carbon steel is the usual wall thickness for Type 1 screw cover pull and junction boxes in this size range, and it holds shape on an 18 x 18 face without oil-canning. It is painted steel, not stainless, so keep it out of damp or corrosive rooms. The enclosure is UL 50 listed and made in the US.
