Milbank U2730-XL-KK – Frequently Asked Questions

1) Will a Milbank U2730-XL-KK ringless meter socket work for a 125A single-phase residential service?
That's exactly what the U2730-XL-KK is built for. It's a 5 terminal, 1 position socket rated 125 continuous amperes at 600V AC, 60 Hz, single phase. The 5 jaw configuration is the standard single-phase 3-wire network/self-contained arrangement utilities use for residential and small commercial service. No main breaker is built in, so overcurrent protection has to live in the panel downstream or in a separate disconnect.
2) What size conductors can I land in the Milbank U2730-XL-KK meter socket?
Line side lugs take 6 AWG through 350 kcmil, and the load side takes 6 AWG through 2/0. That line side range is generous enough for an oversized service lateral or a utility drop run long for voltage drop, but check the load side before you pull: 2/0 is the ceiling on the way out to the panel. All connections are lay-in terminals, so you set the conductor in rather than fishing it through a hole.
3) Can a Milbank ringless meter socket be mounted outdoors on an exterior wall?
Yes. The U2730-XL-KK carries a Type 3R enclosure rating, which covers rain, sleet and ice on an outdoor wall, and it's UL Listed. The body is G90 galvanized steel with a powder coat finish for corrosion resistance. It surface mounts, so it goes on the face of the wall rather than recessed into it, and you'll need a backing surface that can carry a 4.125 x 11 x 15.5 inch enclosure.
4) What does horn bypass do on a meter socket, and do I need it?
Horn bypass lets the utility or an electrician keep power flowing to the building while the meter itself is pulled for testing or replacement. On the U2730-XL-KK the bypass is built into the socket. Whether you need it is usually not your call: many utilities require bypass on their service equipment and some prohibit it, so the utility's approved meter equipment list decides. If yours specifies bypass, this is a bypass socket; if it specifies non-bypass, order a socket without the horn bypass provision.
5) Can I feed a Milbank U2730-XL-KK from an underground lateral, or is it overhead only?
Either. Cable entry is rated for overhead or underground service. The socket ships with a small closing plate over the top hub opening, so for an overhead drop you remove the plate and fit the hub your utility requires. For an underground feed you leave the closing plate in place and bring conductors in through the bottom.
6) Does the Milbank 125A ringless meter socket come with a main breaker or disconnect?
No. It is a socket only, with zero main breakers and no receptacles. That means a service disconnect has to be provided elsewhere, typically the main breaker in the panel immediately downstream or a separate fused disconnect. If you need the disconnect and the meter in one enclosure, you want a meter main combination instead of this socket.
7) Can I use a 125A meter socket on a 200A service?
No. The U2730-XL-KK is rated 125 continuous amperes, and the socket has to be rated at or above the service size. For a 200A service you need a 200A rated socket. Going the other way is fine: this socket will serve a 100A or smaller service as long as the utility accepts the 5 terminal ringless horn bypass configuration.
8) Ringless vs ring type meter socket, which one do I order?
Ringless means the cover itself is what secures and seals the meter, held by a sealable hasp, rather than a separate locking ring clamping the meter to the socket. Neither is better; the serving utility specifies one or the other and will reject the wrong style at inspection. Call the utility or check their meter equipment standard before ordering. The U2730-XL-KK is the ringless style with a small closing plate covering the hub opening.
9) Is the neutral bonded in the Milbank U2730-XL-KK meter socket?
The equipment ground is bonded neutral, meaning the neutral is factory bonded to the enclosure. That matters for where you make the service bond: if the bond happens at the socket, you do not bond again at the panel downstream, and the panel's neutral and ground bars get separated. Internal insulation is glass polyester.
10) I'm standardizing meter sockets across a multi-family property, what should I record for reordering?
Record the Milbank model U2730-XL-KK along with the attributes that have to match unit to unit: 125A continuous, single phase, 5 terminal, ringless, horn bypass, small closing plate, Type 3R. Those seven attributes are what separate this socket from the adjacent Milbank models, and a mismatch on jaw count or bypass provision is what gets a replacement rejected by the utility. The UNSPSC code for procurement systems is 39121102.
