B-LINE 443 SC – Frequently Asked Questions

1) Can the B-Line 443 SC junction box be used outdoors or in a wet location?
No. The 443 SC 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, washdown, dust or oil. For an outdoor or damp area you need a Type 3R or Type 4 enclosure instead. The box is UL 50 listed.
2) What are the actual box dimensions on the B-Line 443 SC screw cover enclosure?
Four inches high by four inches wide with a three inch depth, so it's a 4x4x3 screw cover box. Shipping weight on the unit is 1.6 lb.
3) How many knockouts does the 443 SC junction box have and where are they?
Six total: two on the sides, two on the top and two on the bottom. That gives you straight-through runs either vertically or horizontally without having to punch the enclosure on site.
4) How does this B-Line junction box mount to a wall?
It's a surface-mount box with thru holes in the back pan, so it fastens flat to a wall, panel or strut with your own screws or bolts. Fasteners are not supplied, and the thru-hole design means the mounting hardware passes into the box interior, so allow for that when laying out your wiring.
5) Is the cover on the 443 SC hinged or does it come off completely?
It's a screw cover, not a hinged door, so the cover lifts away entirely once the screws are backed out. The cover uses keyhole slots and plated screws, which means you can loosen the screws and slide the cover off without fully removing them, useful when you're working overhead on a ladder.
6) What is the 443 SC made of and what's the finish?
Carbon steel at 16 gauge wall thickness, painted in ANSI 61 grey. That's the standard grey used on most industrial control and enclosure gear, so it'll blend with existing panels and pull boxes in a plant or mechanical room. Steel construction means it is for dry indoor locations, not corrosive or washdown areas.
7) Is the Eaton B-Line 443 SC UL listed for a commercial electrical inspection?
The enclosure is listed to UL 50, the standard covering enclosures for electrical equipment, and carries a NEMA Type 1 rating. It's made in the US.
8) What is the correct part number to order for this 4x4x3 B-Line screw cover box?
Order it as Eaton B-Line 443 SC. The number reads directly off the dimensions, 4 high by 4 wide by 3 deep, with SC denoting the screw cover version of the enclosure.
