B-LINE 48366 TCF NK – Frequently Asked Questions

1) What are the actual box dimensions of the Eaton B-Line 48366 TCF NK utility cabinet?
The 48366 TCF NK measures 48 inches high, 36 inches wide and 6 inches deep. That 6 inch depth is shallow for a flush wall cabinet, so check your wiring bend space and any breaker or terminal depth before committing. It weighs 155.4 lb, which is a two-person set even before conduit is landed.
2) Can the B-Line 48366 TCF NK be used outdoors or in a washdown area?
No. It carries a NEMA 1 rating, which is indoor use only, protecting against incidental contact with the enclosed equipment and falling dirt. No rain, hose-down, dust or oil protection. For an exterior wall or a wet plant area you need a NEMA 3R, 4 or 4X enclosure instead.
3) Is this B-Line cabinet surface mount or does it go into the wall?
It is a flush mount cabinet with a trim cover, so the box body sets into the wall opening and the trim laps onto the finished surface to hide the rough edge. Plan the framed opening during rough-in, because a flush box is not something you convert to surface mount later. Mounting is through thru holes in the enclosure.
4) Does the 48366 TCF NK come with knockouts for conduit?
No knockouts. The NK in the model designation means the enclosure ships blank, so every conduit entry gets punched or hole-sawed on site to suit your layout. That is the usual choice on a switchgear or control cabinet where the raceway plan is not fixed, but it means you need a knockout punch set on the job.
5) Is this a single door or double door enclosure, and how much clearance do I need in front of it?
Medium double door style, with a hinged cover on heavy-duty butt hinges. Two leaves across 36 inches of width means each door swings roughly half that, so it fits corridors and equipment rooms where a single 36 inch leaf would block the aisle. Still allow full working clearance in front of live parts per your electrical code.
6) What gauge steel is this Eaton B-Line cabinet and what finish does it come in?
Carbon steel in 12 gauge and 10 gauge construction, painted ANSI 61 grey. ANSI 61 is the standard grey used across most industrial switchgear and panelboards, so it matches existing gear in a plant or mechanical room without repainting. Made in the US.
7) Is the B-Line 48366 TCF NK UL listed for a spec job?
It is certified to UL 50, the standard covering enclosures for electrical equipment. Pair that with the NEMA 1 indoor rating when you submit it against a drawing that calls for a general purpose indoor utility cabinet.
8) What is the exact part number to order this 48 x 36 x 6 B-Line flush cabinet?
Order it as Eaton B-Line 48366 TCF NK. The digits read as the dimensions, 48 high by 36 wide by 6 deep, with TCF for the trim cover flush cabinet and NK for no knockouts. Distributors quoting against a cut sheet should match all three segments, since the same size exists in knockout and surface versions.
9) Does this cabinet have anywhere to keep the panel schedule or maintenance record?
Yes, there is a card holder on the door. That is where the panel directory, arc flash record or PM card lives, which is what an MRO or institutional maintenance group wants for standardizing documentation across a facility.
