Milbank U1232-X-HSP – Frequently Asked Questions

1) Does the Milbank U1232-X meter socket come with a main breaker or bypass?
No on both counts. The U1232-X is a straight 2-position ringless meter socket with no main breaker and no bypass provision, so any overcurrent protection has to sit downstream in a separate disconnect or panel. Equipment grounding is handled by a ground lug in the socket. If your utility requires a lever bypass for hot meter pulls, this is not the socket for that job.
2) Is the 150 amp rating per meter position or for the whole Milbank 2-gang socket?
The U1232-X carries a 150 continuous ampere rating at 300 volts AC, 60 hertz, single phase. It is a 4-terminal single-phase socket with two meter positions, and the line and load lugs on both sides take 6 AWG through 350 kcmil, which is what lets it land service conductors sized for that 150A class.
3) Will 4/0 aluminum service entrance cable land in this Milbank meter socket?
Yes. Both line side and load side terminals on the U1232-X accept 6 AWG up to 350 kcmil, so 4/0 falls comfortably inside that range. If you need to land two conductors per terminal, order the U1232-X-5T-K1 version, which ships with double connectors rated for the same 6 to 350 kcmil range.
4) Can this Milbank ringless socket be fed from an overhead drop, or is it underground only?
Either. The U1232-X is built for overhead or underground cable entry and ships with a large closing plate over the hub opening, so you can leave the plate in place and bring conduit in from below for an underground lateral, or remove it and fit the hub your utility specifies for an overhead service mast.
5) What is the difference between the three Milbank U1232-X versions?
Three build options share the same 150A 2-position ringless body. U1232-X is the standard unit. U1232-X-5T-K1 adds double connectors rated 6 AWG to 350 kcmil for landing two conductors per terminal. U1232-X-HSP adds a stainless steel hasp for padlocking the cover, which is what most property managers and institutional buyers want on an accessible exterior wall.
6) Can I use this Milbank socket on a 3-phase service?
No. The U1232-X is a 4-terminal, single phase, 3-wire socket rated 300 volts AC. Three-phase metering needs a 7-terminal socket instead. Trying to meter a 3-phase service through this one is not an option.
7) What wall space do I need for a Milbank U1232-X 2-position meter socket?
Plan for a surface-mounted enclosure measuring 5.125 inches long by 26.5 inches wide by 14 inches high. The 26.5 inch width is the number that catches people out on a 2-gang socket, so check your stud spacing and any clearance the utility requires around the meters before you set it.
8) Is this Milbank meter socket rated for outdoor mounting on a duplex?
Type 3R rated and UL Listed, so it is intended for outdoor use where rain, sleet and ice are the exposure. The enclosure is G90 galvanized steel with a powder coat finish, and internal insulation is glass polyester. That combination is the usual specification for an exterior wall on a duplex or small multi-unit building.
9) Ringless versus ring type meter socket, which one does my utility want?
That is a utility call, not a product call. The U1232-X is ringless, meaning the cover itself locks over the meter and is sealed by the utility rather than using a separate sealing ring. Many utilities specify one or the other exclusively, so confirm with the serving utility before ordering. If ringless is approved, this one covers two single-phase meter positions at 150A on a single enclosure.
10) What else do I have to buy to finish a Milbank U1232-X installation?
The socket has no receptacles and no integral disconnect, so each tenant position needs its own downstream service disconnect and panel. For an overhead feed you supply the hub sized to your conduit, since the unit ships with the large closing plate over that opening rather than a hub. Mounting hardware for the surface-mount enclosure, grounding electrode conductor to the ground lug, and utility seals round out the job.
