Milbank U6238-XT – Frequently Asked Questions

1) Will the Milbank U6238-XT CT enclosure accept 600 kcmil conductors on a 400A service?
The U6238-XT is built around a 400 ampere, 3-phase, 600 volt current transformer installation, with a single mechanical lug on the line side and a single mechanical lug on the load side. The cabinet measures 10L x 24W x 45H inches, which is what gives you bending room for large service conductors landing on those mechanical connections. One lug per landing means one conductor per phase, so if your service is run in parallel sets you need a different cabinet or a separate tap arrangement ahead of it.
2) Does the Milbank CT enclosure come with knockouts, or do I have to punch my own conduit openings?
No knockouts. The U6238-XT ships blank, so the installer drills or punches the cabinet for whatever conduit size and entry location the job calls for, top, bottom, or back. Plan on a hole saw or a knockout punch set on the truck. The upside is you place the entries exactly where the utility and the inspector want them instead of working around factory locations.
3) Is this Milbank CT cabinet rated for outdoor wall mounting on the side of a building?
Yes, it is a NEMA Type 3R enclosure intended for wall mount, so it belongs outdoors on a building wall or a structural backboard, not free-standing on a pad. Type 3R protects against falling rain, sleet, and ice formation. The shell is G90 galvanized steel with a powder coat finish in ANSI 61 Gray, which is the standard utility gray you will already see on the meter stack next to it.
4) Do I need to buy a separate CT mounting rack for the Milbank U6238-XT?
No. The current transformer mounting rack is installed at the factory with lugs already fitted, one per landing. That is the part that usually eats field labor on a CT cabinet, so you are buying the enclosure and the rack as one assembly. You still supply the current transformers themselves and the metering conductors, since those are specified by the utility.
5) What is the difference between a CT cabinet and a meter socket, and which one do I need for a 400A service?
They do different jobs. A meter socket takes the meter directly and is used where the service is small enough to meter through the socket jaws. A CT cabinet like the U6238-XT houses current transformers that scale the service current down to a level the meter can read, which is how utilities meter larger services such as this 400 ampere 3-phase 600 volt arrangement. On a CT-metered service you typically need both: this cabinet for the transformers, plus a separate meter socket or metering trough downstream for the meter itself. The utility's metering standard decides the split.
6) How much wall space do I need to lay out for a 400A CT cabinet before I frame the backboard?
Allow for 45 inches of height, 24 inches of width, and 10 inches of depth off the wall for the U6238-XT, plus the working clearance in front that the electrical code requires for the voltage class. The 10 inch depth matters on a narrow walkway or an alley-side meter bank, since the door swings out past that on a single-door cabinet.
7) Is there a ground point inside the Milbank CT enclosure, or do I have to add one?
A ground stud is provided on the back panel of the U6238-XT, so the bonding point is built in and you are not drilling and tapping the cabinet in the field. Land your grounding electrode conductor or equipment bonding jumper there per the service arrangement the AHJ approved.
8) Can the utility seal the Milbank U6238-XT CT cabinet after inspection?
The cover is a continuous piano hinge design with a 3-point latch, which is the arrangement utilities expect on a CT cabinet because the single latch point can be sealed while the full-length hinge keeps the door aligned and weather-tight over the life of the installation. Always confirm the specific seal provision with the serving utility, since each one publishes its own metering standard.
9) Is the Milbank CT enclosure UL Listed for commercial metering work?
Yes, the U6238-XT carries a UL Listed marking. For an institutional or MRO submittal that is the line the reviewer is looking for alongside the NEMA Type 3R rating. The UNSPSC classification for procurement systems is 39121319.
10) What exact Milbank part number should I put on the purchase order for a 400A 3-phase CT cabinet?
Milbank U6238-XT. That single model covers the 24 x 45 x 10 inch NEMA 3R current transformer enclosure at 400 amperes, 3-phase, 600 volts, with the CT rack and lugs installed. There are no finish or size options to select underneath it, so the base number is the whole order.
11) Will the ANSI 61 Gray finish on this Milbank CT cabinet match the rest of my meter bank?
ANSI 61 Gray is the standard gray used across utility and industrial electrical gear, so a U6238-XT will read as the same color family as most switchgear, meter stacks, and pull sections already on the wall. The finish is powder coat over G90 galvanized steel, which is the corrosion package you want on a coastal or high-humidity site.
