Milbank U4667-X-8031 – Frequently Asked Questions

1) Will a Milbank U4667-X meter socket work on a 480 amp 3-phase 480V service?
The U4667-X is a 480 continuous amp, 3-phase socket rated 600 volts AC at 60 hertz, so a 480V three-phase service sits inside its rating. It's a 7-terminal bolt-in socket, which is the standard jaw arrangement for 3-phase 4-wire metering. Note there is no main breaker and no meter main in it, so overcurrent protection has to come from separate gear downstream.
2) What size conductors can I land in the Milbank U4667-X line side?
Line side takes two 6 AWG to 350 kcmil conductors per phase onto 1/2 inch line side studs. Lug capacity past that depends on which connector option you order: the 8031 build carries 3 double connectors rated 6-350 kcmil, the 8013 adds 5 double connectors at 4-350 kcmil, and the 8512 build steps up to 8 double connectors rated 4-500 kcmil. If you're paralleling 500 kcmil feeders, the 8512 is the one to order.
3) Can a Milbank U4667-X meter socket be mounted outdoors?
Yes. The enclosure is UL Listed and rated Type 3R, which is the weather-resistant rating for outdoor wall mounting, and the box is G90 galvanized steel with a powder coat finish for corrosion resistance. It's a surface mount socket, so it bolts to the wall face rather than recessing into it.
4) What is the DPL version of the Milbank U4667-X and do I need it?
DPL means the build is approved for Delmarva Power and Light. Two versions carry it: U4667-X-8043-DPL with 3 double connectors rated 6-350 kcmil, and U4667-X-8527-DPL with 8 double connectors rated 4-500 kcmil. If the service is in Delmarva territory, order one of those two, because the utility will reject a socket that isn't on its approved list at inspection. Anywhere else, the non-DPL equivalents (8031 and 8512) are the same electrical build.
5) Is one Milbank U4667-X enough to meter multiple tenants in a building?
No. The U4667-X holds a single meter position, so it meters one service. A strip mall or multi-tenant building needing separate billing per space requires either one socket per tenant or a multi-position meter stack. There are also no receptacles and no main breakers in the enclosure, so any tenant disconnects live in separate gear.
6) What does link bypass mean on a meter socket, and do I need it?
Link bypass puts a bolted link across the line and load terminals so the meter can be pulled and swapped while the service stays energized and the load stays up. On the U4667-X that matters for occupied commercial buildings and tenant spaces where you can't drop power to change a meter. Many utilities require bypass on services at this ampere level; if your utility does not, a socket without bypass provision is the simpler order. Check the utility's meter spec sheet, because they specify this, not the electrician.
7) Does the Milbank U4667-X come with a safety barrier over the line side?
Only on two builds. U4667-X-BAR-8532 is the single plate socket with a safety barrier, and U4667-XT-BAR-9572 pairs the barrier with the dual plate configuration. The other builds ship without one. Facilities that require barriered line terminals for arc flash work rules should order one of the BAR versions up front, since the barrier is part of the factory build.
8) What is the difference between the U4667-X and U4667-XT dual plate Milbank sockets?
The XT builds use a dual plate closing arrangement rather than the single plate on the X builds. Images of the 9526 show it as a 7 terminal bolt-in with two large closing plates and link bypass. Dual plate versions are 9504, 9505, 9506, 9526, and the barriered 9572; the 9506 is the higher wire capacity dual plate. All are the same 480 amp, 600V, 3-phase, 7 terminal socket underneath, so the choice comes down to the closing plate arrangement and lug capacity your feeder entry needs.
9) Can I feed a Milbank U4667-X from an underground lateral, or is it overhead only?
Both. Cable entry is overhead or underground, so the same socket serves a weatherhead drop or an underground service lateral. What changes between jobs is the connector build you pick, since the lug count and range per phase differ across the 8013, 8031, and 8512 options.
10) How wide is the Milbank U4667-X meter socket for wall layout?
The enclosure measures 20.25 inches on the width dimension and 6 inches on the length dimension as published. Lay out the wall opening and any adjacent gear from those figures, and remember it's surface mount, so the box stands proud of the wall rather than sitting flush.
11) What insulates the terminals inside the Milbank U4667-X socket?
Glass polyester carries the terminal assembly, with 1/2 inch studs on the line side and bolted rather than jaw-clamped connections at the 7 terminals. Bolt-in terminals are what you want at 480 amps continuous, since bolted joints hold contact pressure under sustained high current better than a spring jaw does.
