Milbank UA4667-X-8062 – Frequently Asked Questions

1) Will a Milbank UA4667 meter socket work on a 480V 3-phase service?
Careful here, the 480 on the Milbank UA4667 is amperes, not volts. It is a 480 continuous ampere socket rated 600 volts AC, so it covers 480Y/277V and 480V delta services within that 600V ceiling, but the amp rating is what the 480 refers to. Frequency rating is 60 Hertz.
2) Is a 7-terminal meter socket the right one for a 3-phase 4-wire service?
Seven jaws is the standard count for a 3-phase 4-wire wye metering installation, and the Milbank UA4667 is a 7 terminal 3 phase socket. If the utility is metering a 3-phase 3-wire delta service they will normally call for a 5-jaw socket instead, and a single-phase residential service takes a 4-jaw. Confirm the jaw count on the utility's meter installation requirements before ordering, since the socket has to match what the meter shop will set.
3) Can the Milbank UA4667 meter socket be mounted outdoors?
Yes. The enclosure is Type 3R and UL Listed, which is the rainproof outdoor rating utilities normally require for an exterior service wall. It is surface mount, so it hangs on the wall face rather than recessing into it. The body is unpainted aluminum with glass polyester insulation on the internals.
4) What does link bypass do on a meter socket, and do I need it?
Link bypass lets the utility jumper the line and load sides through bolted links so power stays on while the meter is pulled or swapped. On a commercial building where you cannot drop the whole service to change a meter, that matters. The Milbank UA4667 carries the link bypass provision as built. Many utilities specify bypass on services this size, so check the utility's spec sheet, because a non-bypass socket will get rejected on inspection if they require it.
5) Does the Milbank UA4667 meter socket include a main breaker or disconnect?
No. It is a meter socket only, with no main breaker and no receptacles, so the service disconnect and overcurrent protection have to be provided separately downstream (or upstream, per the utility's arrangement). If you need metering and a main in one enclosure, you want a meter main, not this unit.
6) How do the line conductors land in the Milbank UA4667 socket, are there lugs?
Line side is 1/2 inch stud terminals, not mechanical lugs. That means you land on studs with terminations sized for the run, which at 480 amps usually means multiple conductors per phase or bus. Plan the terminations before the socket goes on the wall, because stud landings and lug landings are not the same prep.
7) What is the difference between the UA4667-X and UA4667-XT closing plate options?
The Milbank UA4667 comes three ways. UA4667-X-8062 and UA4667-X-8529 are single large closing plate builds (configurations 8062 and 8529), and UA4667-XT-9527 is the dual large closing plate version, configuration 9527. The closing plate arrangement is what covers the unused hub or entry openings, so pick the one that matches how your conduit and cable are entering the enclosure. The XT part number is the one to specify when you need two plates.
8) Can I feed a Milbank UA4667 meter socket from underground, or does it have to be an overhead service?
Either one. Cable entry is overhead or underground, so the same socket works for a weatherhead drop or a lateral coming up from below. That flexibility is why one part number covers both service types on a commercial job.
9) How wide is the Milbank UA4667 meter socket, will it fit my wall space?
The socket measures 20.25 by 6 inches on the width and length figures Milbank publishes. On a crowded service wall, the 20.25 inch dimension is the one that usually decides whether it lands clear of adjacent gear, so check that against the space between your conduit runs.
10) Is unpainted aluminum a problem for a coastal or corrosive install?
Unpainted aluminum is the standard utility finish and it holds up outdoors under the Type 3R rating, but there is no factory paint or coating on it. In heavily corrosive or salt-air environments, or where an architect wants a finished look, specify a painted or stainless enclosure instead. Interior parts use glass polyester insulation.
11) What UNSPSC code should I use for a Milbank meter socket on a purchase order?
UNSPSC 39121102 covers the Milbank UA4667 bolt-in meter socket. Institutional and government buyers who classify electrical distribution material by UNSPSC can code it straight off that number.
