B-Line Eaton series utility enclosures

The 30304 TCF NK cabinet measures 30 inches high by 30 inches wide with a 4 inch depth. It is a medium double door style, so you get two doors across that 30 inch width rather than one wide swing, which matters when you have limited clearance in a corridor or equipment room. Shipping weight is 70.8 lb, so plan on two people to set it.

Flush mount. The 30304 TCF NK is built to recess into the wall, and it ships with a trim cover to close the gap between the cabinet and the finished wall surface. If your install is on a block or concrete wall where you cannot cut a 4 inch deep pocket, this is the wrong cabinet and you want a surface mount enclosure instead.

No. It carries a NEMA 1 rating, which is general purpose indoor only, protecting against incidental contact with the enclosed equipment and falling dirt. It is not rated for rain, hosedown, dust or corrosive locations. For an exterior wall, a loading dock or a wet process area you need a NEMA 3R, 4 or 4X enclosure.

It uses a T-handle with 3-point latching, so the door pulls tight at the top, middle and bottom rather than at a single point. The handle has a key locking provision, and the doors ride on heavy duty butt hinges. For a facility standardizing on keyed access to telecom or control cabinets, that T-handle is the piece to match across your other enclosures.

It is built to UL 50, the standard covering enclosures for electrical equipment. That, with the NEMA 1 rating, is what a spec on a drawing typically calls for on an indoor general purpose cabinet. It is also made in the US, which matters if your project carries a domestic sourcing requirement.

Through holes in the enclosure body, so you provide the fasteners suited to your framing or substrate. Nothing is welded on for mounting. Since it recesses flush and the trim cover laps the wall finish, set your rough opening before the drywall or panel goes up and anchor the box to the studs behind it.

Yes, there is a card holder on the door. For MRO and facilities crews that is where the circuit directory, the panel schedule or the service record lives, so a tech opening the cabinet a year later knows what it feeds without tracing anything.
