Milbank UC7237-XL – Frequently Asked Questions

1) What is the Terminal Option number I have to pick when ordering the Milbank UC-XL meter socket?
The Milbank UC-XL ringless CT socket is ordered by terminal count, and five choices exist: 5 terminals (UC1290-XL), 6 (UC1299-XL), 7 (UC7233-XL), 8 (UC7235-XL), and 13 (UC7237-XL). The terminal count has to match the utility's metering scheme for the service, single phase versus three phase and the number of CT and potential leads being brought in. Get the count from the utility's meter specification before you order, because the socket interior differs between them.
2) Will this Milbank socket work for an underground service lateral, or is it overhead only?
Either. Cable entry is rated for overhead or underground, so the same socket serves a mast-fed overhead drop or an underground lateral. It ships with a small closing plate on the hub opening, so for an overhead feed you remove the plate and fit the hub size the conduit calls for; for an underground feed the plate stays in place and the conduit comes in from below.
3) What does the auto bypass on this Milbank meter socket do, and do I need it?
The auto bypass shorts the metering circuit automatically when the meter is pulled, so the CT secondaries stay closed and service is not interrupted while the meter is out for testing or replacement. Many utilities require a bypass on CT metering for exactly that reason. If your utility specifies a manual or lever bypass instead, or no bypass, specify a different socket, since the bypass type is built into the unit and cannot be added later.
4) What wire size do the terminals on this Milbank CT meter socket take?
Both line and load side terminals are rated 12 to 10 AWG, with single mechanical lugs. CT secondary leads are typically run in that range, so standard 10 AWG control wire lands fine. Anything larger than 10 AWG will not fit the lug.
5) Can this Milbank ringless socket be installed outdoors on an exterior wall?
Yes. The enclosure is UL Listed and Type 3R, which is the rain, sleet and ice rating for outdoor service equipment, and it is built from G90 galvanized steel with a powder coat finish for corrosion resistance. It is a surface mount unit, so it bolts to the face of the wall or a backboard rather than recessing into it.
6) How much wall space do I need for the Milbank 20 amp CT meter socket?
The enclosure measures 14 x 8 x 3.313 inches (height, width, length as published). Plan the surface mount location with clearance for the hub or conduit entry above and the utility's required working space in front.
7) Does this meter socket include a main breaker or receptacle?
No. It is a metering enclosure only, with zero main breakers and zero receptacles, and one meter position. Overcurrent protection and any disconnect have to come from separate equipment downstream or upstream, per the utility and the AHJ.
8) Is a ringless socket the right choice, or do I need a ring type?
Ringless means the cover itself retains the meter and is sealed by the utility, with no separate sealing ring. Which one you can install is dictated by the serving utility, not by preference, and the two are not interchangeable in the field. These Milbank UC-XL units are ringless, so confirm your utility accepts ringless CT sockets before ordering.
9) Can I use this 600 volt Milbank socket on a 480Y/277V three phase service?
The voltage rating is 600 volts AC, which covers 480Y/277V and the lower 208Y/120V and 240V services. The deciding factor is the terminal arrangement, not the voltage: three phase CT metering generally needs a higher terminal count than single phase, and the UC-XL family runs from 5 up to 13 terminals. Match the terminal option to the utility's wiring diagram for that service.
