B-LINE 48486 SC NK – Frequently Asked Questions

1) Can a NEMA 1 junction box like the B-Line 48486 SC NK be used outdoors or in a washdown area?
No. The 48486 SC NK carries a NEMA Type 1 rating, which is indoor, dry-location use only. It gives protection against incidental contact and falling dirt, not rain, hose-down, dust-tight service or corrosive atmospheres. For outdoor or wet locations you need a Type 3R, 4 or 4X enclosure instead.
2) Does this B-Line enclosure come with knockouts for conduit?
No knockouts. The 48486 SC NK is supplied blank, so every conduit entry is field-drilled or punched where you want it. That is why it suits pull and junction applications where the conduit layout is set on site, but it does mean you need a punch set or hole saw rated for 12 gauge carbon steel.
3) How is this 48 x 48 junction box mounted, and can one person hang it?
Surface mount through pre-provided thru holes in the back of the enclosure. At 183.6 lb it is not a one-man lift, and the substrate matters: on a stud wall you need blocking or a strut rack, and hardware is not included with the box. Plan for two people plus a lift or strut frame.
4) Is the B-Line 48486 SC NK junction box UL listed for a commercial or institutional spec job?
The enclosure is built to UL 50, the standard for enclosures for electrical equipment, and it is made in the US. If your drawing calls for a UL 50 Type 1 screw cover enclosure, this meets that callout at 48 x 48 x 6.
5) Is the cover on the B-Line 48486 SC NK hinged or does it come off?
It is a screw cover, not a hinged one, built as a medium double door style. The cover has keyhole slots so you can back the plated screws out part way and lift the cover off the slots rather than fully removing every fastener, which helps when you are working the box alone at height.
6) Can I mount devices or a terminal strip inside this B-Line box?
It ships as a bare Type 1 screw cover enclosure with no knockouts and thru holes in the back for mounting the box itself. Any back panel, mounting rails or terminal blocks are separate items you order and drill for. With only 6 inches of depth, check the projection of whatever you plan to mount plus wire bending room before you commit to it.
7) How do I order this exact B-Line enclosure, and what does the part number mean?
Order Eaton B-Line model 48486 SC NK. The digits read as the dimensions, 48 high by 48 wide by 6 deep, SC for screw cover, NK for no knockouts. There is a single configuration, so there are no finish or size options to pick on this one.
