Milbank U4808-X-21-BLG – Frequently Asked Questions

1) Which amperage and voltage combinations does the Milbank U4800 series ringless CT cabinet come in?
Three build-outs are offered, all with a single front cover with hasp: U4808-X-21-BLG at 200-400A, 120-208V; U4810-XT-21-BLG at 400-800A, 120-208V; and U4809-XT-21-BLG at 400-800A, 277-480V. Pick by the service size and the utility's secondary voltage on the job. All are 3 phase, 60 hertz, and rated 600 volts AC as an enclosure class.
2) Can a Milbank ringless CT cabinet be mounted outdoors on an exterior wall?
Yes. The cabinet is a Type 3R enclosure, so it is built for outdoor wall mounting where rain, sleet and ice are the exposure. It is surface mount, and the shell is G90 galvanized steel with a powder coat finish for corrosion resistance. It is UL Listed.
3) Does this Milbank CT cabinet include a main breaker or a meter bypass?
No on both counts. The U4800 ringless CT cabinet ships with no main breaker and no bypass provision. It houses the current transformers and the prewired test switch only, so overcurrent protection has to come from separate gear upstream or downstream. There is one meter position and no receptacles.
4) Will a 13 terminal CT cabinet work for a 3 phase 4 wire wye service?
The Milbank U4800 CT cabinet is built with 13 terminals on glass polyester insulation, which is the standard landing count for 3 phase transformer rated metering, and it is offered in both 120-208V wye and 277-480V configurations. Match the terminal block arrangement and the CT ratio to your serving utility's metering spec before the meeting.
5) Can service conductors enter this CT cabinet from underground, or is it overhead only?
Either. Cable entry is rated for overhead or underground, so the same cabinet works for a pole-fed lateral or a padmount-fed underground service. A ground lug is provided for the equipment grounding connection.
6) How does the barrel lock provision work on this Milbank CT cabinet?
The cabinet comes with a 7/8 inch knockout and an angle bracket sized for a utility barrel lock, plus a hasp on the single front cover. That lets the serving utility seal the enclosure against unauthorized access after the CTs are installed. Most utilities supply the barrel lock itself, so it is not part of the cabinet.
7) What is the difference between a ringless CT cabinet and a ring-type meter socket?
A ringless enclosure uses a removable cover secured by a hasp and lock rather than a sealing ring around the meter, which is what most utilities in ringless territory require. Beyond that, this unit is a CT cabinet, not a self-contained socket: it houses current transformers and a prewired test switch for transformer rated metering on services too large to meter directly, and is offered up to 800A. A self-contained socket with jaws is the right choice for smaller services.
8) Is the test switch already wired in, or does the electrician have to field wire it?
The test switch is factory prewired in the Milbank U4800 CT cabinet, so the technician does not have to build that circuit in the field. It lets a meter tech verify or swap the meter without opening the CT secondaries.
9) What is the cabinet depth on the Milbank U4800 CT cabinet?
The stated product length is 10 inches. Verify the wall clearance and conductor bending space against your utility's CT cabinet requirements for the amperage you are running, since 800A conductors need considerably more working room than 200A.
10) Is this CT cabinet suitable for a school or municipal building metering upgrade?
It is built for exactly that kind of work: 3 phase transformer rated metering, UL Listed, Type 3R for outdoor mounting, in 200-400A and 400-800A sizes at 120-208V or 277-480V. The G90 galvanized steel with powder coat holds up on exterior walls. For a facility standardizing across multiple buildings, the same 13 terminal layout and barrel lock provision runs across all three configurations.
