B-LINE 36306 SC NK – Frequently Asked Questions

1) Can a NEMA Type 1 junction box like the B-Line 36306 SC NK be installed outdoors or in a washdown area?
No. The 36306 SC NK carries a NEMA 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It offers no protection against rain, hose-down, dust ingress, or corrosive atmospheres. For a wet or outdoor location you need a NEMA 3R, 4, or 4X enclosure instead.
2) What are the box dimensions on the B-Line 36306 screw cover junction box?
It measures 36 inches high, 30 inches wide, and 6 inches deep, which is where the 36306 designation comes from. That 6 inch depth is the number to check first if you are stacking terminal blocks or landing large conductors with bending radius to respect.
3) Does this Eaton B-Line junction box come with knockouts already punched?
No knockouts. The SC NK box ships blank on all sides, so the installer drills or punches conduit entries where the job needs them. Budget for hole saws or a knockout punch set, plus the appropriate connectors, since none are included.
4) How is this B-Line box mounted, and how much weight does the wall have to carry?
Surface mount, using thru holes in the back of the enclosure. The box alone weighs 84.5 lb empty, so anchor into studs, strut, or masonry with hardware rated for that plus the wiring and devices you add. Mounting hardware is not supplied.
5) What gauge steel is this junction box, and will it hold up in a plant or mechanical room?
Carbon steel at 12 gauge, which is heavier wall than the 14 and 16 gauge typical of light commercial pull boxes. That thickness resists denting in a mechanical room, plant floor, or loading area and supports internal panels and terminal strips without flexing.
6) Is this junction box UL listed for a spec job?
The 36306 SC NK is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. For a submittal, the pairing to cite is UL 50 with the NEMA Type 1 rating.
7) What is the exact part number to order this 36 x 30 x 6 B-Line box?
Order it as Eaton B-Line 36306 SC NK. The number reads height, width, depth (36 x 30 x 6), SC for screw cover, NK for no knockouts.
8) What color is the Eaton B-Line 36306 enclosure, and is it primed or finish painted?
It arrives painted in ANSI 61 grey, the standard grey used across most industrial control and distribution equipment. No field painting is needed to match adjacent panels finished in the same standard.
