Milbank U1855-O-NE – Frequently Asked Questions

1) Will the Milbank U1855-O-NE CT enclosure work outdoors on an exterior wall?
Yes. The U1855-O-NE current transformer enclosure carries a Type 3R NEMA rating, which covers outdoor service against rain, sleet and ice formation, and it is built for wall mounting. The shell is G90 galvanized steel with a powder coat finish in ANSI 61 grey, which is the standard exterior-grade combination for utility metering gear on a building wall.
2) How much wall space do I need for a Milbank 12x36x36 current transformer enclosure?
Plan for a 36 by 36 inch footprint on the wall with 12 inches of projection off it. The catalogued size is 12L x 36W x 36H inches, so the box stands 36 inches tall, spans 36 inches across, and comes 12 inches out from the mounting surface. Give yourself working clearance in front of that 12 inch depth, because both doors swing out.
3) Does the Milbank U1855-O-NE come with knockouts for conduit entry?
No knockouts. The U1855-O-NE ships as a blank box, so the installing electrician punches or hole-saws the conduit entries where the run actually lands. That is deliberate on a CT can: line and load conduit positions vary by service, and the utility usually dictates where they enter. Budget for hole punching tools and the right sealing fittings to keep the Type 3R rating intact after you cut.
4) Do I have to buy a separate mounting rack for the current transformers?
No, the rack is already in the box. The U1855-O-NE comes with the current transformer mounting rack installed, complete with lugs at three per landing. There is also a ground stud on the back panel. What you are buying separately is the CTs themselves, the conduit fittings, and the wall mounting anchors.
5) Is this Milbank CT cabinet approved for a Northeast Utilities service?
Yes, the U1855-O-NE is built to the Northeast Utilities specification, which is why the O-NE suffix is on the model number. If your service falls under a different utility's metering requirements, order the enclosure built to that utility's spec instead, because CT can approvals are utility by utility and an unapproved cabinet gets rejected at inspection.
6) What kind of line and load connections does this Milbank CT enclosure have?
Single mechanical line side and single mechanical load side. That means one mechanical lug landing per phase on each side, so it suits a single set of conductors in and a single set out. If your service brings in parallel conductor sets per phase, this configuration will not land them and you need a cabinet with multiple lugs per phase.
7) How do the doors open on the Milbank U1855-O-NE, and can I take the cover off completely?
It is a double door design with a lift off hinge cover, so both doors swing open for wiring and either can be lifted straight off the hinge pins for full, unobstructed access to the CT rack. That matters when you are setting transformers and dressing large line conductors in a 12 inch deep box, where a fixed door in the way costs you real time.
8) Is the Milbank current transformer enclosure UL Listed?
Yes, the U1855-O-NE is UL Listed. Between that and the Type 3R rating, it satisfies the two things an inspector and a facility electrical standard normally ask of an outdoor CT cabinet on a commercial service.
9) Will a galvanized CT enclosure hold up in a coastal or wash-down environment?
The U1855-O-NE uses G90 galvanized steel with a powder coat finish, which is the standard corrosion package for outdoor service equipment and handles ordinary weather exposure well. It is not stainless. For salt spray, chemical exposure, or regular hose-down, a Type 4X stainless or non-metallic enclosure is the right call rather than a painted galvanized 3R box, and note that Type 3R is a rain and ice rating, not a hose-directed-water rating.
10) What is the exact part number to order this Milbank CT enclosure on a purchase order?
Order Milbank U1855-O-NE. That is the full manufacturer part number for the 12 x 36 x 36 inch Type 3R current transformer enclosure with the double door and the Northeast Utilities configuration. The O-NE portion is the piece that identifies the utility build, so dropping it off the PO risks the wrong cabinet arriving.
11) Do I have to paint the Milbank CT cabinet to match the rest of the switchgear?
No paint needed in most cases. The enclosure arrives powder coated in ANSI 61 grey, the standard gear grey used across utility metering and switchboard equipment, so it lines up with existing service equipment on the wall without field finishing.
