Milbank U1253-RRL-KK-K1-BLG-SLVG – Frequently Asked Questions

1) Will 4/0 aluminum SER land in a Milbank U125 meter socket?
Yes. Both line and load terminals on the U125 socket take 6 AWG through 350 kcmil, so 4/0 aluminum sits comfortably inside that range. The lugs are single mechanical terminals, meaning one conductor per terminal per phase, so a parallel feed will not land here. Equipment grounding is a ground lug.
2) Does the Milbank U125 meter socket include a main breaker or main disconnect?
No. The U125 is a meter socket only, with no main breaker and no receptacles. You are providing the service disconnect separately, either as a utility-side main ahead of it or as tenant disconnects downstream of each position. Budget panel space and conduit accordingly, because this enclosure is metering and wireway only.
3) Can the Milbank 200 amp ringless socket be mounted outdoors on a building wall?
Outdoor wall mounting is what it is built for. The U125 socket is UL Listed and Type 3R rated, surface mount, with a G90 galvanized steel body and powder coat finish for weather exposure. Internal insulation is glass polyester. Type 3R covers rain and falling debris outdoors; it is not a washdown or submersion enclosure.
4) Will my utility accept a ringless socket, or do they require a ring type?
Ringless versus ring type is a utility decision, not an installer preference. The Milbank U125 is a ringless socket, meaning the cover locks over the meter without a sealing ring, and utilities that specify ringless will reject a ring type sealed unit and vice versa. Check the serving utility's approved meter equipment list before ordering, and confirm they accept a 4 terminal, single phase, horn bypass socket.
5) Can I feed a Milbank U125 socket from an underground lateral, or is it overhead only?
Either. The U125 accepts overhead or underground cable entry and uses a center wireway, so service conductors can come down from a weatherhead or up from a lateral and route to each meter position through the middle of the enclosure. Knockout selection at the top or bottom is what sets the entry direction on the job.
6) Is the Milbank U125 meter socket rated for 240 volt single phase residential service?
Yes. The U125 socket is rated 300 volts AC at 60 hertz, single phase, which covers standard 120/240 volt single phase residential and light commercial service. It is not a three phase socket, so a 120/208 three phase or 277/480 service needs different equipment entirely.
7) Will a 4 terminal Milbank socket work with my utility's meter?
A 4 terminal socket takes a standard single phase self-contained form meter with four jaws, two line and two load. If the utility is setting a 5 jaw or 7 jaw meter, the U125 is the wrong socket and you need a socket matching that jaw count. Confirm the meter form the utility will set before the enclosure goes on the wall, because the socket cannot be reconfigured in the field.
8) What does the horn bypass on a Milbank meter socket actually do for me?
Horn bypass lets the utility or a qualified tech pull the meter without dropping power to the tenant. The bypass horn shunts current around the meter socket jaws so the load stays energized during a meter change or test. On a multi-position U125 feeding apartments, that means a meter swap does not mean a call from every unit in the building. Sockets without a bypass provision require a full outage for the same work.
9) Does the Milbank U125 socket have a provision for a barrel lock?
It does. The U125 comes with a 7/8 inch knockout and an angle bracket for a barrel lock, so a utility or property manager can secure the cover where lock-off is required. The barrel lock itself is a separate purchase, and utilities typically supply their own.
10) Does a 6 position Milbank U125 mean the service needs to be 1200 amps?
No. The 200 amp continuous rating on the U125 is the rating of each meter position, not a sum. A 6 position unit gives six 200 amp single phase tenant meters, but the incoming service and the bussing feeding those positions are sized by the utility and the service calculation, typically well below the arithmetic total because of diversity. Size the lateral and the service disconnect from the load calc, not from position count times 200.
11) What is the difference between the U1252 and U1254 Milbank meter socket suffixes?
Beyond position count, the suffix block changes. The 2 and 3 position units are U1252-RRL-KK-K1-BLG-SLVG and U1253-RRL-KK-K1-BLG-SLVG, while the 4, 5 and 6 position units carry an RXL designation instead of RRL: U1254-RXL-KK-K1-BLG-SLVG, U1255-RXL-KK-K1-BLG-SLVG and U1256-RXL-KK-K1-BLG-SLVG. If a utility or spec sheet calls out the full part number, match the whole string, not just the U125 base.
