B-LINE 30304 TCS NK – Frequently Asked Questions

1) Can the Eaton B-Line 30304 TCS NK enclosure be used outdoors or in a washdown area?
No. The 30304 TCS NK cabinet is a NEMA 1 enclosure, which is for indoor use only and gives protection against incidental contact and falling dirt. It is not rated for rain, hose-down, dust-tight or oily environments. For a wet or outdoor location you need a NEMA 3R, 4 or 4X enclosure instead.
2) What are the box dimensions on the B-Line 30304 TCS NK utility cabinet?
It measures 30 inches high, 30 inches wide and 4 inches deep. That 4 inch depth is shallow, so check your wire bending space and breaker or terminal depth before committing, and note the door is a medium double door style.
3) Does this B-Line utility enclosure come with knockouts for conduit?
No knockouts. The 30304 TCS NK is supplied blind, so every conduit or cable entry has to be punched or hole-sawed on site in the 12 gauge carbon steel. Plan for a knockout punch set and touch-up paint on the cut edges.
4) How does the door lock on the Eaton B-Line TCS NK cabinet?
It uses a T-handle with 3-point latching, so the door pulls in at the top, middle and bottom rather than at a single point. The handle is key locking, which is what utilities and facility groups typically want on a cabinet that has to stay closed to unauthorized hands.
5) How is this 30 x 30 B-Line cabinet mounted to the wall?
Surface mount, through thru holes in the back of the enclosure. You supply the anchors sized to the wall you are fastening into. Weight matters here: the cabinet runs 67.7 lb empty, so block or masonry anchors, or fastening into studs or Unistrut, rather than drywall toggles.
6) What gauge steel and finish is the B-Line 30304 TCS NK made from?
Carbon steel at 12 gauge on both body and cover, painted in ANSI 61 grey. ANSI 61 is the standard grey used across most industrial control gear, so it matches adjacent panels and starters in a typical electrical room.
7) Is the B-Line TCS NK enclosure UL listed?
It carries UL 50, the standard covering enclosures for electrical equipment. Paired with the NEMA 1 rating, that is what an inspector will be looking for on an indoor surface-mounted cabinet.
8) Does the hinged door on this B-Line cabinet come off, and is there anywhere to keep drawings inside?
The door is hinged on a heavy-duty butt hinge and the cabinet ships with a trim cover and a card holder on the door, which is where crews normally keep the circuit schedule or equipment card. Closure and cover are both hinged rather than screw-on lift-off.
9) What part number do I order for the 30 x 30 x 4 B-Line TCS cabinet, and where is it made?
Order Eaton B-Line model 30304 TCS NK. It is made in the US.
