Milbank U4015-O – Frequently Asked Questions

1) Will the Milbank U4015-O meter socket work for an overhead service drop, or is it underground only?
Underground only. The U4015-O is built for underground cable entry with a plain top, meaning there is no hub opening punched in the lid for a service mast or weatherhead conduit. If you are feeding from an overhead drop you need a socket with a hub or hub opening instead. For an underground lateral coming up into the bottom of the can, this is the right configuration.
2) What size service conductors fit the Milbank 200A ring type meter socket?
The lay-in terminals take 6 AWG through 350 kcmil on both the line and load sides, so 4/0 aluminum or 2/0 copper 200-amp service conductors land without an adapter, and smaller 100A or 150A feeders are still within range. Lay-in style means the conductor drops into the jaw terminal rather than threading through a hole, which is faster on large stiff aluminum.
3) Does this Milbank socket have a main breaker or disconnect built in?
No. The U4015-O is a meter socket only, with no main breaker and no bypass provision. You still need a separate service disconnect or a panel with a main downstream of it. If your utility or inspector requires a bypass lever for hot meter changes, this is not the unit.
4) Is a 4 terminal ring type socket right for 120/240V single phase residential service?
Yes, that is exactly the application. Four jaws on a single-phase socket handles two line conductors and two load conductors, which is standard 120/240V three-wire residential and light commercial service at 60 Hz. Three-phase service needs a 7-jaw socket instead, and a 5-jaw is used for certain network configurations.
5) Will the utility accept a ring type meter socket, or do they require ringless?
That depends entirely on your serving utility. Ring type sockets use a sealing ring to clamp the cover over the meter, and many utilities specify ring type while others require ringless with a hinged cover. The U4015-O is a ring type unit, so confirm your utility's approved equipment list before ordering, because the two are not interchangeable in the field.
6) Can I run 480V three phase through a 600V rated meter socket like this?
No. The 600V AC rating is the insulation voltage ceiling, not a license for three-phase use. This socket is wired as 1 phase with 4 terminals, so it only serves single-phase service. A 480V three-phase installation needs a 7-jaw three-phase socket, typically with instrument transformer provisions above 200A.
7) How much wall space do I need for the Milbank U4015-O, and can it mount on a pedestal?
The enclosure measures 5L x 14W x 16.25H inches and is configured for surface mount, so it fastens flat to a wall, backboard, or a flat-faced meter pedestal. The 5 inch depth is what to watch on tight installations with conduit behind. It is not a flush or semi-flush can.
8) Can this meter socket be installed outdoors in rain and coastal weather?
It is UL Listed and rated Type 3R, which is the standard outdoor rating for rain and sleet on service equipment. The can is G90 galvanized steel with a powder coat finish for corrosion resistance, and internal insulation is glass polyester. Type 3R is not a washdown or dust-tight rating, so for hosedown or heavy dust environments you want a higher enclosure type.
9) Does the U4015-O include a ground connection for a triplex service?
Yes, the socket is furnished with a triplex ground provision, so the bare messenger of an underground or triplex service conductor set has a landing point in the can. Grounding electrode conductor sizing and bonding still follow your local code and the AHJ's requirements.
10) Can I meter two units with this Milbank socket?
No. It is a single meter position socket with no auxiliary receptacles. For a duplex or multi-unit property where each tenant needs separate billing, you need a multi-position meter stack or individual sockets per unit.
11) What is the exact part number to order this Milbank 200A underground meter socket?
Order Milbank U4015-O. It falls in Milbank's 4T20 product family, the 4-terminal 200-amp group, and the O suffix corresponds to the underground, plain-top configuration. If a utility spec sheet calls out a hub or a bypass, you need a different suffix in that family.
12) What UNSPSC code should I use for this meter socket on a government purchase order?
The Milbank U4015-O carries UNSPSC 39121102, which is the classification line for meter sockets. That is the code to drop into a government, healthcare, or education procurement record for this item.
