B-LINE 666 SC NK – Frequently Asked Questions

1) Can the Eaton B-Line 666 SC NK junction box be used outdoors or in a washdown area?
No. The 666 SC NK is a NEMA Type 1 enclosure, which is indoor-only protection against incidental contact and falling dirt. It has no rating for rain, hose-down, dust-tight or corrosive locations. For outdoor or wet areas you need a Type 3R or Type 4 box instead.
2) Does the B-Line 666 junction box come with knockouts for conduit?
It does not. The SC NK designation means no knockouts, so the carbon steel body ships blank and you punch or drill your own conduit openings wherever the run lands. That is useful when hole placement has to match existing conduit, but it does mean a knockout punch or step bit is part of the job.
3) Is the Eaton B-Line 666 SC NK a UL listed enclosure?
It is built to UL 50, the standard covering enclosures for electrical equipment. That is the certification carried on this Type 1 screw cover box, and it is the one an inspector or facility spec typically calls out for indoor junction boxes.
4) How does the 666 SC NK enclosure mount to a wall?
Surface mounting through holes in the back of the box. The mounting holes are thru holes, so fasteners pass all the way through the enclosure wall and into the wall or strut behind it. Hardware for the wall itself is not part of the box, so pick anchors or bolts to suit the substrate.
5) Is the cover on this B-Line junction box hinged or does it screw on?
It is a screw cover, not a hinge. The cover has keyhole slots so once the plated screws are backed off a turn or two you can lift the cover clear without removing them entirely, which helps when you are working one-handed on a ladder.
6) Should I order a no-knockout box or one with knockouts for a standard branch circuit pull box?
If your conduit entries are standard trade sizes in predictable spots, a box with factory knockouts saves field time. The 666 SC NK is the blank version, meant for jobs where the entry locations are not standard or where you want a sealed body until you open it. Field-punched holes also let you keep the Type 1 box tidy with no unused knockouts to plug.
7) What is the exact part number for the 6x6x6 B-Line screw cover box with no knockouts?
Order it as Eaton B-Line 666 SC NK. The 666 gives the 6 x 6 x 6 inch dimensions, SC is screw cover, NK is no knockouts. It is made in the US.
8) What gauge steel is the 666 SC NK box and what color does it come in?
The body is 16 gauge carbon steel, painted ANSI 61 grey, which is the standard grey used across most industrial control and junction enclosures, so it blends with existing panels on a wall. It weighs 4 pounds.
