Milbank U5838-O – Frequently Asked Questions

1) Can the Milbank U5838-O current transformer enclosure be installed outdoors?
Yes. The U5838-O carries a NEMA Type 3R rating, which covers outdoor use against rain, sleet and ice formation. The shell is G90 galvanized steel with a powder coat finish in ANSI 61 gray, so it holds up on an exterior wall at a service entrance. It is not a washdown or dust-tight rating, so for hose-down or heavy dust areas you want a 4 or 12 rated box instead.
2) What are the actual dimensions of the Milbank U5838-O CT enclosure, and how much wall space do I need?
The box measures 10.125 inches deep (length) by 36 inches wide by 36 inches high. Plan on a 36 by 36 inch wall footprint plus clearance in front of the double doors to swing them fully for CT work.
3) Does the Milbank U5838-O come with conduit knockouts, or do I have to punch my own?
No knockouts. The U5838-O ships blank so you punch or hole-saw the entries where your conduit runs land, top, bottom or side. Budget time for that in the install, and plan on your own weathertight hubs for any top entry since a 3R box relies on the entry being sealed properly.
4) Do I need to buy a separate rack to mount the current transformers in the Milbank U5838-O?
No. A current transformer mounting rack is included with the U5838-O, so the CTs land on a factory rack rather than something you fabricate. The back panel also carries a ground stud for bonding.
5) Is this Milbank CT cabinet UL Listed for a utility service entrance?
The U5838-O is UL Listed. It is built as a current transformer enclosure for metering service, and utilities commonly require a listed CT cabinet ahead of the meter. Your serving utility still has final say on cabinet size and sealing provisions, so match the box to their service requirements sheet.
6) Single door or double door on the Milbank U5838-O, and why does it matter?
Double door. Across a 36 inch wide opening, two hinged doors cut the swing clearance roughly in half compared with one 36 inch door, which matters in a tight equipment room or an alley wall. It also gives you full-width access to the CT rack and conductors for installation and later service.
7) Can the U5838-O CT enclosure be floor or pad mounted?
It is configured for wall mount. The U5838-O is meant to be fastened to a structural wall; for a freestanding pad installation you need a pedestal or rack-mount style CT cabinet instead. At 36 by 36 inches, anchor into studs, masonry or an equivalent backing rather than sheathing alone.
8) What model number do I order for a 10 x 36 x 36 Milbank CT cabinet?
Order Milbank U5838-O. That is the 10.125 by 36 by 36 inch NEMA 3R double door current transformer enclosure, part of Milbank's CTEN current transformer enclosure family.
9) Will the Milbank U5838-O match the gray gear already on my building?
The finish is ANSI 61 gray powder coat over G90 galvanized steel, the standard utility and switchgear gray, so it reads the same as most panelboards, meter stacks and CT cabinets already on a commercial wall. Good choice if you are standardizing enclosure appearance across a site.
