B-LINE 483616-SD – Frequently Asked Questions

1) What are the actual outside dimensions of the B-LINE 483616-SD enclosure?
Outside, it runs 48 inches high, 36 inches wide and 16 inches deep. That 16 inch depth is what makes it usable for a real control panel: a back panel, DIN rail, starters and wireway all fit with door clearance left over. Lay out your wall space for the full 48 x 36 face plus swing room for a single hinged door.
2) How much does a 48 x 36 x 16 steel enclosure like this weigh, and what does that mean for hanging it?
Empty, it is 134.1 lb. Add a back panel and components and you are well past that, so it is a two-person lift and the wall needs real structure. Mounting is through holes in the back of the box; optional external mounting feet are available if you would rather stand it off the wall or you are fastening to unistrut or block. On stud wall, land the fasteners in studs or a plywood backer, not drywall anchors.
3) Will this enclosure satisfy a spec calling for a UL listed NEMA 4 wall mount enclosure?
It carries UL 50 certification and a NEMA 4 rating, which is what most control panel specs cite for an enclosure of this type. It is also made in the US, which helps on public and institutional jobs with domestic sourcing language in the contract.
4) Does the B-LINE 483616-SD come with a back panel?
The enclosure is the shell, hinged cover, gasket and latching hardware. A back panel is the usual separate order on an SD-style box, and so are the external mounting feet noted as optional. Plan on specifying those with the enclosure if your drawing calls for subpanel-mounted components.
5) How does the door latch, and can it be padlocked or opened without tools?
Closure is a 1/4 turn operator driving a 3-point latching system, so the door pulls tight at three points along the edge for even gasket compression. No tools needed to open it, which matters for a panel an electrician services regularly, and the 3-point arrangement is what keeps a 48 inch tall door sealing at top and bottom rather than bowing in the middle.
6) Is 14 gauge steel heavy enough for an industrial control panel enclosure?
The walls are 14 gauge carbon steel, which is the standard body thickness for industrial NEMA 4 wall boxes in this size and is stiff enough to carry a loaded back panel without oil-canning. Finish is painted ANSI 61 gray, the usual control panel color, so it will match existing MCC and panel shop equipment on the same wall.
7) Can I drill conduit holes in this enclosure and keep the NEMA 4 rating?
Yes, but only with watertight fittings. The box ships without knockouts on the gasketed face, and any penetration you make has to use a hub or fitting rated for wet locations, otherwise the NEMA 4 seal is gone at that hole. Standard practice is to enter the bottom or sides rather than the top. The poured in-place gasket around the door itself is not affected by field drilling elsewhere in the body.
8) What is the part number to order for the B-LINE 48 x 36 x 16 single door enclosure?
The manufacturer part number is 483616-SD, a B-LINE medium single door wall mount enclosure. The digits read height, width, depth: 48 high, 36 wide, 16 deep, with SD for the single door series.
