Milbank UC7449-XL-871-ALT – Frequently Asked Questions

1) What does the 20 amp rating on a Milbank UC7449 transformer-rated meter socket actually mean for my service size?
The 20 continuous ampere rating is the socket's own rating, not the size of the service it meters. These are CT-cabinet style sockets (product family CT20) wired to current transformers, so the service current stays in the CT gear and only the metering leads land in this can. That is why the line and load side wire range is 12 to 10 AWG, which is instrument wiring, not service conductors. If you are looking for a socket that carries the full load current, this is the wrong part.
2) What is the difference between the Milbank UC7448 and UC7449 meter socket?
Terminal count. The UC7448-XL is the 8 terminal version and the UC7449-XL is the 13 terminal version. Pick the one the utility's meter form calls for: 8 terminal for the shorter test-switch arrangement, 13 terminal where the meter form needs the extra points. Everything else, 600V, 3 phase, 20A continuous, single meter position, is common to both.
3) Do I have to wire the test switch myself, or can I order a Milbank meter socket with it prewired?
Both are available. The UC7448-XL and UC7449-XL come with the test switch provision only, so you mount and wire the switch in the field. The prewired versions ship with the test switch already installed and landed: UC7448-XL-341 in 8 terminal, and UC7449-XL-871 or UC7449-RL-411 in 13 terminal. Prewired saves the electrician the bench work and removes a source of miswiring at the utility inspection.
4) Which Milbank meter socket do I order for an Alliant Energy job?
UC7449-XL-871-ALT is the Alliant Energy configuration, 13 terminal with the test switch prewired. Utility metering equipment is approved by list, so if the drawing or the service application names Alliant, order the ALT suffix rather than the standard UC7449-XL-871.
5) Can I pull the meter and keep power on with a Milbank UC7449 socket?
No. These sockets have no bypass provision, so there is no way to maintain service through the can while the meter is out. On a facility that cannot take an outage for a meter change, you need a socket ordered with a lever or horn bypass instead. The test switch versions do let a technician test and verify metering without disturbing the meter itself.
6) How much wall space do I need for a Milbank UC7448 ringless meter socket?
Plan on a 4.125 x 12 x 20 inch footprint (length x width x height as the spec states it), surface mounted. Height is 20 inches, width 12 inches, and it stands 4.125 inches off the wall, so allow clearance in front for the meter and the working space your inspector requires.
7) Can a Milbank ringless meter socket be mounted outdoors on the side of a building?
Yes. The enclosure is Type 3R and UL Listed, which covers rain, sleet and ice on an outdoor wall. The shell is G90 galvanized steel with a powder coat finish for corrosion resistance, and internal insulation is glass polyester. Type 3R is not a washdown or dust-tight rating, so it is not the enclosure for an indoor process area that gets hosed down.
8) Does the Milbank UC7449 meter socket take an overhead service drop or an underground lateral?
Either. Cable entry is rated for overhead or underground, so the same socket works whether the service comes down from a weatherhead or up from a lateral. Note the hub arrangement differs by part: UC7449-RL-411 is the small hub open version, while the UC7448-XL ships with a double cover and small closing plate.
9) Does the Milbank UC7448 meter socket include a disconnect or receptacle?
No. It is a metering enclosure only: zero main breakers, no main breaker provision, no bypass, and no receptacles. Any service disconnect, overcurrent protection, or convenience outlet has to be ordered as separate gear alongside it.
10) How does the equipment ground land in a Milbank UC7448 meter socket?
A ground lug is provided for the equipment grounding conductor, and the terminals are single mechanical type, so conductors are landed under set screws with no crimping or added lugs needed. Terminal wire range is 12 to 10 AWG on both line and load side.
