Milbank UCSSP3433-O – Frequently Asked Questions

1) Does the Milbank UCSS 13 terminal meter socket carry the service current, or is it for CT metering only?
It is rated 20 continuous amperes at 600V AC, which is instrument-transformer (CT) rated metering, not service-rated. The 13 jaw arrangement and 20A rating mean the socket carries only the secondary current from current transformers on a 3 phase service, not the full load. Wire ranges bear this out: both line and load side lugs take 12 to 10 AWG only. If you need the socket in the service conductor path, this is the wrong device.
2) What is the difference between Milbank UCSS3433-O and UCSSP3433-O?
Test switch provision. UCSSP3433-O comes with the test switch, UCSS3433-O without. The test switch lets a meter tech shunt the CT secondaries and isolate the potential leads to test or swap the meter without opening a CT secondary or dropping the customer. Utilities frequently mandate it on CT installations, so check the serving utility's metering spec before picking between the two.
3) Can this Milbank 13 terminal socket be installed outdoors on an exterior wall?
Yes. It is UL Listed and Type 3R rated, so it is built for outdoor rain-tight service, and it is a surface mount enclosure that fastens flat to a wall or backboard. The body is 304 stainless steel with a powder coat finish, which holds up in coastal and industrial air better than painted galvanized.
4) Does the Milbank UCSS3433-O include a bypass or a main breaker?
Neither. It is a no-bypass, no-main-breaker socket with a single meter position and no receptacles. Overcurrent protection and any disconnecting means have to come from separate equipment. If your utility requires a lever bypass on the meter can, specify a different socket.
5) Is the top of this Milbank socket pre-punched for a conduit hub?
No. It ships plain top, with no hub opening, and the cable entry is configured for underground service. If you are coming in overhead with a rigid riser, this enclosure is not set up for it as supplied.
6) Will 10 AWG CT secondary leads land in this socket, and how do I ground it?
Yes, the single mechanical terminals accept 12 to 10 AWG on both line and load sides, which is the usual range for CT secondary and potential conductors. Equipment grounding is handled by a factory ground lug in the enclosure.
7) Is this Milbank socket suitable for a 480Y/277V 3 phase commercial service?
Yes, it is rated 600 volts AC, 60 Hertz, 3 phase, so it covers 480Y/277V and 208Y/120V CT metering installations. The glass polyester insulating base is what carries that 600V rating.
8) Is this a ring type or ringless meter socket?
Ring type. The meter is retained by a sealing ring around the cover collar rather than a ringless lift-off cover. Many utilities specify one or the other, so match the arrangement your serving utility accepts before ordering.
9) What is the UNSPSC code for the Milbank UCSS meter socket for our purchasing system?
UNSPSC 39121102. Milbank also groups it under product family code CT20, which is useful when cross-referencing the CT metering line on a submittal.
