Milbank U3850-O-TG – Frequently Asked Questions

1) Will the Milbank U3850-O meter socket work for a 200 amp underground residential service?
That is exactly what it is built for. The U3850-O is a single phase, 200 continuous amp ringless socket with underground cable entry through a side wireway, rated 600V AC at 60 Hz. It is a 4 terminal, single meter position socket with a plain top (no hub), surface mounted, in a Type 3R enclosure for outdoor service entrance work.
2) Does this Milbank ringless socket include a main breaker or disconnect?
No. The U3850-O is a meter socket only, with no main breaker and no receptacles. Main breaker size is listed as No Main Breaker and breaker count as zero, so the service disconnect and overcurrent protection have to come from a separate panel or disconnect downstream.
3) What does the KK suffix mean on the Milbank U3850-O-TG-KK?
KK denotes the horn bypass option. U3850-O-TG-KK is the triplex ground socket with horn bypass, U3850-O-QG-KK is the quadplex ground with horn bypass, and U3850-O-TG is the triplex ground without it. Many utilities require a bypass so the meter can be pulled without dropping the customer's service, so check the utility's approved meter socket list before you pick between TG and TG-KK.
4) Plain top versus hub top meter socket, which do I need for an underground service?
Plain top is the right call for underground. The U3850-O has a plain top closing plate, meaning no hub opening on the top of the can, because the service conductors come up from below through the side wireway rather than down through an overhead mast. If your service is overhead with a riser into the top of the socket, you want a hub top socket instead, not this one.
5) Is a 4 terminal Milbank socket right for 120/240V single phase, or do I need a 5 jaw?
Four terminal is the standard configuration for 120/240V single phase, three wire residential and light commercial metering, and that is what this socket is: 4 jaws, one meter position, one phase, rated to 600V AC. If your utility meters a network or three phase service, they will call for a 5 jaw or 7 jaw socket instead and this one will not accept that meter.
6) What is the difference between the triplex ground and quadplex ground versions of the U3850-O?
It comes down to how many service conductors the socket's grounding and connector arrangement is set up for. The triplex versions (U3850-O-TG and U3850-O-TG-KK) suit a three conductor triplex service drop; the quadplex version, U3850-O-QG-KK, is for a four conductor quadplex arrangement. All are the same 4 terminal ringless plain top body with a side wireway.
7) Is there a version of this Milbank socket approved for Alliant Energy territory?
Yes. U3850-O-TG-KK-ALT is the Alliant Energy variant, triplex ground with horn bypass. If you are working in an Alliant service area, order that one rather than the standard TG-KK, since utilities specify their own accepted configurations.
8) How much wall space do I need for this Milbank meter socket?
The enclosure measures 4.5 inches deep by 13 inches wide by 15.25 inches high and mounts to the surface of the wall. Allow for the side wireway when you lay out conduit and adjacent equipment, and keep the meter within the utility's required height window off finished grade.
9) Can this Milbank socket be mounted outdoors on an exterior wall?
Yes. It is a Type 3R enclosure, which is the outdoor rating for rain, sleet and ice, and the body is G90 galvanized steel with a powder coat finish for corrosion resistance. It is also UL Listed.
10) Do I need a meter ring with this Milbank socket?
No ring is needed. It is a ringless design, where the cover itself secures the meter, which is what most utilities in ringless territories require. Utilities are split on ringless versus ring type, so confirm which your local utility accepts before ordering a batch for multiple units.
