B-LINE 866 SC – Frequently Asked Questions

1) Can the B-Line 866 SC junction box be used outdoors or in a wet location?
No. The 866 SC is a NEMA Type 1 enclosure, which is indoor-use only and protects against dust and incidental contact, not water. For a washdown area, a rooftop, or anywhere exposed to rain or hose spray, you need a NEMA 3R, 4 or 4X box instead. Indoor dry locations such as electrical rooms, mechanical spaces, and above ceilings are what this one is built for.
2) Does the 866 SC come with knockouts, or do I have to punch my own conduit holes?
Knockouts are already provided: 4 on the sides, 3 on the top, and 3 on the bottom. That gives you straight-through runs top to bottom plus side entries for branch conduit without pulling out a punch set. If your layout needs an entry where there is no knockout, you would be drilling or punching the carbon steel body yourself.
3) How does the 866 SC mount to a wall?
Surface mount, using thru holes in the back of the box, so you fasten it directly to the wall, strut, or backboard with your own screws or bolts. Anchors and fasteners are not part of the box. It is not a flush or recessed enclosure, so the body sits proud of the finished wall by its full 6 inch depth.
4) Is the B-Line 866 SC a UL listed enclosure?
It is built to UL 50, the standard covering enclosures for electrical equipment, and carries a NEMA Type 1 rating. That is the combination most inspectors look for on an indoor junction or pull box in commercial work.
5) What are the actual box dimensions of the B-Line 866 SC?
It measures 8 inches high, 6 inches wide, and 6 inches deep, so it fits in a 6 inch stud bay depth footprint on a wall face. Shipping weight of the box is 4.8 lb, light enough for one person to hold while driving the mounting screws.
6) Screw cover versus hinged door, which should I pick for a junction box I have to open often?
The 866 SC has a screw-on cover, which is the right choice for a pull or splice box you rarely reopen: fewer parts, and the cover cannot be swung open casually. The cover has keyhole slots and plated screws so you can back the screws out part way and lift the cover off rather than chasing loose hardware. If you are terminating controls or anything you expect to service regularly, a hinged-cover enclosure is the easier one to live with.
7) What gauge steel is the 866 SC, and will it hold up in a mechanical room?
The body is 16 gauge carbon steel with a painted finish in ANSI 61 grey, which is the standard commercial enclosure gauge and colour. It takes knocks in a plant or mechanical room without denting the way a light sheet box does, and the ANSI 61 grey matches typical switchgear and panel finishes on the same wall.
8) What is the exact part number to order this B-Line box, and where is it made?
Order it as Eaton B-Line 866 SC, the SC (screw cover) version of the 8 x 6 x 6 Type 1 box. It is made in the US.
