B-LINE 864 WPSC – Frequently Asked Questions

1) Does this B-Line enclosure carry a UL listing for an inspected commercial job?
Yes, UL 50 is the certification on file for the 864 WPSC, which is the standard covering enclosures for electrical equipment. It is also made in the US, which helps on Buy American and domestic-content specs.
2) How does the 864 WPSC mount to a wall or strut?
Surface mount, using external mounting feet welded to the back of the box. Because the fastener holes are outside the enclosure, you are not drilling through the back wall and you keep the Type 3R seal. The whole box weighs 4.2 lb, so two anchors sized for the substrate are enough on block, drywall with backing, or a strut channel run.
3) Does the B-Line 864 WPSC come with conduit knockouts or is it blank?
The 864 WPSC is a screw-cover junction box with a flanged cover and no knockouts called out in its specification. Plan on drilling or punching your own hub openings and using watertight hub fittings to keep the Type 3R seal intact. The body is 16 gauge carbon steel, so a standard Greenlee-style punch handles it cleanly.
4) Is the 864 WPSC painted, and what color will it match on an existing panel lineup?
It ships painted in ANSI 61 gray, the standard gray used across industrial enclosures and switchgear, so it will sit alongside existing B-Line and other ANSI 61 panels without looking off. Note the finish is paint over carbon steel, not stainless or galvanized, so in salt air or washdown areas a stainless enclosure is the better call.
5) Screw cover or hinged door, which should I use for this size box?
The 864 WPSC uses a gasketed screw-on cover. That is the right choice for a splice or pull point you rarely open, since the sealing screws are what hold the NEMA 3R rating. If the box houses a device someone opens routinely, such as a disconnect or a controller, a hinged-door enclosure saves you handling loose screws at height on every visit.
6) What is the exact part number to order this B-Line box?
Order it as B-Line (Eaton) model 864 WPSC. That is the manufacturer part number, and the WPSC suffix identifies the screw-cover, gasketed weatherproof series rather than a hinged or flat-cover box.
7) What are the inside dimensions of the 864 WPSC box, and will a 4 inch deep device fit?
The 864 WPSC measures 8 inches high, 4 inches wide and 4 inches deep. In B-Line's numbering, the 864 designation follows that same 8 x 6... no, read it straight from the spec: height 8 in, width 4 in, depth 4 in. Those are the box's stated overall figures, so a device needing a full 4 inches of clear depth will not clear the gasket and cover surface. Step up to a deeper WPSC box for anything close to 4 inches deep.
