B-Line Eaton series CT lift off cover, 3R, 12 gauge steel, ANSI 61 gray paint, Galvanized steel, 1P or 3P, Lift off cover

Yes. The Eaton B-Line 303611 RTCT current transformer cabinet carries a 3R degree of protection, which is the outdoor rating for rain, sleet and snow, and it is UL listed. Surface mounting is the intended method, so it bolts to a wall or a structural backing rather than flush into it.

The cabinet measures 30 in high, 36 in wide and 11 in deep. Allow clearance above it as well: the lift off cover comes straight off the front, so you mainly need working room in front, but the 36 in width is the governing number for fitting between conduit runs or adjacent metering equipment.

Both. The 303611 RTCT is rated for single phase or three phase current transformer applications, so the same cabinet covers a residential or small commercial single phase service and a three phase commercial service.

It weighs 115 lb, so plan on two people to lift and hold it while the fasteners go in. At that weight on a surface mount, fasten into studs, blocking or masonry anchors rather than sheathing alone. The lift off cover means the front panel comes away entirely during rough-in, which drops some of that weight while you are positioning the box.

A lift off cover, like the one on the 303611 RTCT, is a full front panel that unbolts and comes away completely. That gives you unobstructed access to the whole interior for pulling large service conductors and setting CTs, which is why utilities commonly specify it on CT cabinets. A hinged door stays attached and swings, which is faster for repeat access but leaves the door in your way during the pull. If the utility spec on your job calls for a hinged and sealable door, this is not that version.

Body construction is 12 gauge steel over galvanized steel, finished in ANSI 61 gray paint. The 12 gauge wall is heavier than the 14 or 16 gauge typical of general purpose enclosures, which is what lets a 30 x 36 box carry service conductors and CTs without the sides oil canning.

No. It is a 3R enclosure, which handles falling rain, sleet and snow outdoors but is not a watertight or dust tight rating. For hosedown or washdown areas you want a 4 or 4X enclosure, and for a dust tight indoor industrial space a Type 12. Use the 3R cabinet for exterior wall mount service and metering work.

The finish is ANSI 61 gray, the standard light gray used across most North American switchgear, panelboards and metering equipment, so it lines up visually with the rest of a typical service lineup. Underneath the paint the body is galvanized steel, which is what carries it outdoors in the 3R rating.
