Milbank U1255-X-KK-K1 – Frequently Asked Questions

1) Will a 4 terminal ringless meter socket work for a standard 200 amp residential single phase service?
That's exactly what the Milbank U1255-X is built for. It's a 4 jaw, single phase socket rated 200 continuous amperes at 300 volts AC, 60 Hz, which covers a typical 120/240V single phase residential or light commercial service. Four jaws is the standard single phase self-contained arrangement. Before you set it, confirm your serving utility accepts a ringless cover socket, since some utilities specify ring type instead.
2) Does this Milbank meter socket come with a main breaker or disconnect?
No. The U1255-X is a meter socket only, with no main breaker and no receptacles. You'll need a separate service disconnect or a main breaker panel downstream of it. If you want metering and the disconnect in one enclosure, you're looking for a meter main combination instead, not this socket.
3) What size conductors can I land in a 200A Milbank U1255-X meter socket?
Load side lugs take 6 AWG through 350 kcmil. That range covers the usual 200 amp service conductors, including 2/0 copper or 4/0 aluminum SER, with room up to 350 kcmil if the run length pushed you to upsize for voltage drop.
4) Can this meter socket be mounted outdoors on an exterior wall?
Yes. It's UL Listed with a Type 3R enclosure rating, which is the rain tight rating used for outdoor service equipment, and the can is G90 galvanized steel with a powder coat finish for corrosion resistance. It's a surface mount unit, so it bolts flat to the wall or a backing board rather than recessing into it.
5) What is the difference between the hub options on the Milbank U1255-X, K1 through K4?
The base U1255-X ships with a large closing plate over the hub opening, so you can bring conduit in through the plate or through a hub you add later. The hub-equipped versions come with the hub factory fitted: K1, K2, K3, and K4 are the available hub sizes, ordered as U1255-X-K4, U1255-X-K2-CAPL (which adds a sealing cap), and the KK combinations. Pick the hub that matches the service entrance conduit your utility requires overhead; if you're feeding underground from below, the standard large closing plate version is usually what you want.
6) What does the KK in the Milbank U1255-X-KK part numbers mean?
KK is the horn bypass option. A horn bypass lets the utility pull or change the meter without dropping power to the customer, and many utilities require it on 200 amp services. It's available combined with hubs, for example U1255-X-KK-K1 with a K1 hub or U1255-X-KK-K4-PED for pedestal mounting. If your utility doesn't call for bypass, the plain U1255-X is the one to order.
7) My utility spec sheet lists a BL, BLG, DLC or QG code. Which Milbank part do I order?
Those suffixes are utility specific builds of the same 200 amp 4 terminal socket. Order U1255-X-KK-K3-BL for BL, U1255-X-KK-K3-BLG for BLG, U1255-X-KK-K3-DLC for DLC, and U1255-X-QG-KK-K4 for QG. All four include the horn bypass. Match the letter code on your utility's approved equipment list exactly, because a socket built to a different utility's spec will fail inspection even though the electrical ratings are identical.
8) Is there a lockable version of this Milbank meter socket for a property where tampering is a concern?
Yes, U1255-X-HSP is the same 200 amp ringless socket built with a stainless steel hasp, which gives you a padlock point on the cover. That's the one property managers usually want on multi-family and rental sites where the meter stack is publicly accessible. The hasp version has to be ordered as such; you can't add it to the plain U1255-X later.
9) Ringless versus ring type meter socket, which one do I need?
It's the utility's call, not yours. The Milbank U1255-X is ringless, meaning the cover itself slides over the socket and is sealed rather than being clamped by a separate sealing ring. Ringless is common across much of the country and makes cover removal simpler for meter work. If your serving utility's approved list specifies ring type, this socket won't be accepted and you need a ring type can instead.
10) Is there a version of this Milbank socket for a pedestal or freestanding installation instead of a wall?
U1255-X-KK-K4-PED is the pedestal mount build, with horn bypass and a K4 hub. Use that one where there's no building wall to hang the meter on, such as a manufactured home site, a well or pump service, or a lot where the service lands at the property line. The rest of the U1255-X family is surface mount for wall installation.
11) For a procurement spec, what UNSPSC code and product family does this Milbank socket fall under?
The UNSPSC is 39121102 and Milbank's family code for it is G200. Those two plus the MPN, U1255-X for the base unit, are what you need to line it up on a purchase requisition or an approved materials list.
