B-LINE 666 SC – Frequently Asked Questions

1) Can the B-Line 666 SC junction box be used outdoors or in a wash-down area?
No. The 666 SC is a NEMA Type 1 enclosure, which is indoor use only, for protection against incidental contact and falling dirt. It gives no protection against rain, hose-down, dust ingress or corrosive environments. For a wet or outdoor location you need a Type 3R or Type 4 enclosure instead.
2) How many knockouts does this 6x6x6 screw cover junction box have and where are they?
Knockouts come on three faces: 3 side, 3 top and 3 bottom. That lets you bring conduit in from the sides and run straight through top to bottom, so the box works as a pull point or a splice point without drilling. The back is solid for surface mounting.
3) How does the B-Line 666 SC mount to a wall?
It is a surface mount enclosure with thru holes in the back pan, so you fasten it directly to the wall, panel or strut with your own hardware. Mounting screws or anchors are not part of the box, so pick fasteners to suit the substrate. At 4 lb empty it is light enough for most wall types.
4) Is this B-Line junction box UL listed for an inspected commercial installation?
Yes, the 666 SC carries UL 50 certification, the standard for enclosures for electrical equipment. Paired with its Type 1 rating, that covers indoor general purpose use on commercial and institutional work.
5) What are the actual box dimensions of the B-Line 666 SC?
It is a 6 x 6 x 6 inch box: 6 inch height, 6 inch width and 6 inch length/depth. That is the nominal enclosure size, so allow for the screw cover and conduit hubs when you lay out the wall space.
6) Is the cover on this junction box hinged or does it screw on?
It is a screw cover, not hinged. The cover has keyhole slots so you can back the plated screws out part way and lift the cover off instead of removing them completely, which keeps the screws with the box when you are up a ladder. If you need frequent access with the cover staying attached, look for a hinged door enclosure instead.
7) What is the exact part number to order this Eaton B-Line 6x6x6 screw cover box?
Order it as B-Line (Eaton) model 666 SC. The number reads directly off the size: 6 high, 6 wide, 6 deep, SC for screw cover. It is made in the US.
8) What is the B-Line 666 SC made of and what is the finish?
Carbon steel at 16 gauge, painted in ANSI 61 grey. That is the standard grey that matches most commercial panelboards and control enclosures, so it blends with existing gear on a facility standardization job. Steel, not stainless, so keep it out of corrosive or damp locations.
