Milbank UC3425-XL – Frequently Asked Questions

1) What does the Terminal Option number mean on the Milbank UC342 meter socket, and how do I pick one?
The UC342 ringless meter socket is ordered by terminal count: 13 terminals (UC3423-XL), 5 terminals (UC3425-XL), 6 terminals (UC3426-XL), or 8 terminals (UC3428-XL). That number is the only difference you specify on the order. Everything else stays the same across all four: single meter position, 20 continuous ampere, 600V AC, 60 Hz, ringless, with provision for a test switch. Match the terminal count to the utility's metering scheme for the service you're wiring; the utility or the meter tech dictates it, not the socket.
2) What size wire can I land in the Milbank UC342 meter socket?
Both line side and load side terminals on the UC342 take 12 to 10 AWG, on single mechanical lugs. That's CT secondary and metering wire, not service entrance conductors. If you're pulling anything heavier than 10 AWG into it, you have the wrong socket for the job.
3) Can a Milbank ringless meter socket be mounted outdoors?
Yes. The UC342 carries a Type 3R enclosure rating and is UL Listed, so it's built for outdoor wall mounting where rain and ice are in play. The shell is G90 galvanized steel with a powder coat finish, with glass polyester insulation inside. Type 3R is not a washdown or dust-tight rating, so don't put it where it gets hosed down or sits in blowing dust.
4) Does the Milbank UC342 meter socket have a bypass, or will the power be off while the meter is out?
There is no bypass provision in the UC342. It does have provision for a test switch, which is how you test and service the metering on a CT installation without dropping the customer's load. If your utility requires a lever or horn bypass socket, the UC342 will not satisfy that spec and you need a bypass-equipped socket instead.
5) Does the Milbank UC342 socket include a main breaker or disconnect?
No breaker, no disconnect, no receptacles. The UC342 is metering only, a single position socket with zero main breakers. Your service disconnect and overcurrent protection have to be provided separately, either in a combination panel downstream or a separate disconnect ahead of it depending on how the service is laid out. Buy the disconnect as a separate line item on the order.
6) Do I need a meter ring for the Milbank UC342, and what about the hub?
No ring needed. The UC342 is a ringless socket, so the two-piece front holds the meter without a sealing ring, which is what most utilities in ringless territory require. On the top, it comes with a small hub closing plate, so if you're bringing conduit in overhead you drill or cut that plate for the hub you need rather than ordering a separate cover for an unused opening.
7) Can I standardize on one Milbank meter socket across a portfolio of buildings with different utilities?
Partly. The UC342 body is the same across all four orderable versions, 600V AC, 60 Hz, Type 3R, UL Listed, single position, same 5.125 x 12 x 20 inch enclosure, so the mounting detail and the wall opening repeat from site to site. What does not standardize is the terminal count, which comes in 5, 6, 8, and 13 terminal versions because each serving utility specifies its own metering arrangement. Spec the enclosure once, then confirm terminal count per utility before each release.
8) Will the Milbank UC342 work on a 480V three phase service?
The UC342 is rated 600 volts AC at 60 hertz, so it covers the common 120/240, 208Y/120, and 480Y/277 volt utility services in North America by voltage class. The deciding factor is not voltage but the metering form the utility specifies, which is what the terminal count (5, 6, 8, or 13) has to match. Get the form from the utility first, then order the matching terminal option.
9) How is the equipment ground made up in a Milbank UC342 meter socket?
A ground lug is provided in the enclosure for the equipment grounding connection, so you don't have to add a separate ground bar kit to land the EGC. Everything landing in the box is in the 12 to 10 AWG range.
