Milbank UF7021-KO – Frequently Asked Questions

1) Will a Milbank UF7021-KO meter socket work for a 200 amp single phase residential service?
Yes. The UF7021-KO is rated 200 continuous amperes, single phase, 600V AC at 60 Hz, with one meter position and a 4 terminal jaw configuration. That 4 jaw, 1 phase arrangement is the standard single phase 3 wire residential and light commercial service socket. It has no main breaker and no bypass, so the disconnect and overcurrent protection live downstream in a separate panel or in the utility's arrangement.
2) Is the Milbank UF7021-KO for overhead or underground service entrance?
Overhead. Cable entry on the UF7021-KO is overhead, and there is no hub opening in the top of the can, so it is not set up to take a threaded hub for a mast riser conduit. For an underground lateral you want a socket built for underground entry instead. Check what the serving utility requires on the meter before ordering either way, since most of them publish an approved socket list by entry type.
3) What wire size can I land in a Milbank UF7021-KO 200A meter socket?
Both line and load terminals take 6 AWG through 350 kcmil, so 4/0 aluminum SER or 2/0 copper for a 200 amp service lands without an adapter, and you have headroom up to 350 kcmil if the utility pulls larger service conductors. The terminals are lay-in type, which means the conductor drops into the jaw pocket rather than threading through a closed lug, so you are not fishing 4/0 through a hole in a tight can.
4) Does the Milbank UF7021-KO come with a main breaker, or do I need a separate disconnect?
No breaker in the can. The UF7021-KO carries no main breaker, zero breaker positions, no bypass provision and no receptacles. It is a meter socket only, so plan on a separate service disconnect and distribution panel downstream. If you want the meter and the main in one enclosure, you are looking for a meter main combination rather than this socket.
5) Will a 4 terminal meter socket work for 208V three phase or a 120/208 network service?
No. The UF7021-KO is a 4 jaw, single phase socket. Three phase metering needs a 7 jaw socket, and a 120/208 network service typically calls for a 5 jaw. Ordering the 4 terminal for a three phase service means the meter will not seat and the utility will reject the install. The 600V AC rating on this socket refers to the insulation class, not to a service voltage you can pick freely.
6) Ringless versus ring type meter socket, which one does my utility want?
A ringless socket like the Milbank UF7021-KO uses a removable cover that the utility seals directly, instead of a sealing ring clamping the meter to the socket rim. Which style you install is not an installer preference, it is dictated by the serving utility, and the two are not interchangeable in the field. Most of the western and midwestern US utilities specify ringless; much of the east specifies ring type. Confirm on the utility's approved meter equipment list before you buy, because a socket in the wrong style will not get released for service.
7) Is the Milbank UF7021-KO neutral bonded, and do I need a separate ground bar?
The equipment ground on the UF7021-KO is a bonded neutral, meaning the neutral is bonded to the enclosure at the socket. That is the normal arrangement where the meter socket sits ahead of the service disconnect. Downstream of the service disconnect, grounds and neutrals get separated, so do not carry that bond forward into your subpanels.
8) Can a Milbank ringless meter socket be mounted outside in the weather?
Yes. The UF7021-KO enclosure is UL Listed and rated Type 3R, which is the rainproof outdoor rating used for service equipment. The can is G90 galvanized steel with a powder coat finish, and the jaw block is glass polyester insulation. Type 3R sheds rain, sleet and snow; it is not a washdown or corrosive duty rating, so a coastal or heavy chemical exposure site is worth a harder look at the environment.
9) Can I pull the meter and keep power on with the Milbank UF7021-KO?
No. The UF7021-KO has no bypass provision, so removing the meter opens the service. If your job needs the load kept live during meter changes or testing, such as a healthcare or data facility, specify a socket with a horn bypass or lever bypass instead. Many utilities also mandate bypass above a certain service size or for commercial accounts, so check that requirement before choosing a no-bypass socket.
10) What do the flange knockouts on the Milbank UF7021-KO do, and do I need a hub?
The knockouts are the pre-scored conduit entries you punch for your service raceway or load conduit, and the flange is what laps the finished wall on a flush installation. There is no hub opening in this can, so it does not accept a threaded meter hub for a rooftop mast. Overhead conductors come in through the knockouts, and any weatherproofing at the entry is your fitting selection, not something built into the socket.
