Milbank U1234-X-HSP – Frequently Asked Questions

1) How much wall space do I need for a Milbank 4-position 150A ringless meter socket?
Plan for a surface-mounted enclosure measuring 5.125L x 42.688W x 16H inches. That 42.688 inch width is the dimension that catches people out on narrow walls or between-stud locations, since all four meter positions sit side by side in one gangable enclosure. It bolts to the wall surface, so no recess or back box is needed.
2) Is the 150 amp rating per meter position or for the whole Milbank 4-gang socket?
The 150 continuous ampere rating is the socket rating at 300 volts AC, 1-phase, 60 Hz. It is a 4-position, 4-terminal ringless socket with no main breaker and no bypass provision, so overcurrent protection for each tenant has to come from separate equipment downstream. If you need a main disconnect or lever bypass built in, this is not the unit for that job.
3) What size service conductors will fit the lugs on this Milbank 150A 4-position meter socket?
Line side terminals take 4 AWG through 600 kcmil, or two conductors from 1/0 AWG through 250 kcmil when you are paralleling. Load side lands 6 AWG through 350 kcmil. Equipment grounding is by ground lug. If your service lateral is larger than 600 kcmil single, you will need a separate gutter or trough ahead of the socket.
4) Can this Milbank ringless meter socket be used for an underground service, or is it overhead only?
Both. Cable entry is rated for overhead or underground service. It ships with a large closing plate over the hub opening, so for an overhead drop you remove the plate and fit the hub your utility specifies; for an underground lateral you leave the closing plate in place and bring conduit in through the bottom.
5) Will a 150A 1-phase meter socket work on a 3-phase commercial service?
No. This is a 1-phase, 4-terminal socket rated 300 volts AC. Three-phase metering needs a 7-terminal socket and a different enclosure entirely. For single-phase 120/240 tenant metering in apartments, strip centers and mixed-use buildings, the 4-position layout is the right fit.
6) Is a Type 3R meter socket OK to mount outdoors on an apartment building?
Yes. The enclosure is UL Listed and carries a Type 3R rating, which covers rain, sleet and falling dirt, so exterior wall mounting is the normal application. The shell is G90 galvanized steel with a powder coat finish for corrosion resistance, and internal insulation is glass polyester.
7) Ringless versus ring-type meter socket, which one do I order for a multi-family service?
That call belongs to your serving utility, not to the installer. This Milbank unit is a ringless design, meaning the meter is held by a sealable pull-down cover rather than a separate locking ring. Many utilities now specify ringless for tenant metering because the cover can be sealed and opened without removing a ring. If your utility's handbook calls for ring-type, a ringless socket will not pass their inspection.
8) What is the difference between the two ordering options on the Milbank U1234-X 4-position socket?
Two configurations are offered. U1234-X-5T-K3 is built with a single connector rated 4 to 600 kcmil for the line side. U1234-X-HSP is the version supplied with a stainless steel hasp for padlocking the cover. Pick the hasp version where the property requires the enclosure locked rather than just utility sealed.
9) Does this Milbank 4-position socket include tenant breakers or receptacles?
No. There are zero main breakers and zero receptacles in the unit, and no bypass provision. It is strictly a 4-position metering enclosure, so tenant disconnects and branch panels are separate purchases. Budget for those when you price out the service.
10) What is the Milbank product family code for this 4-gang 150 amp socket, for matching the rest of a job?
It falls under Milbank family code G150, with base part number U1234-X. Useful if you are standardizing meter stacks across several buildings and want the same socket style, closing plate and amperage on every service.
