Milbank UC1299-RL – Frequently Asked Questions

1) Will a Milbank UC1299-RL 20A meter socket work for a standard 200 amp residential service?
No. The UC1299-RL is rated 20 continuous amperes, which is a transformer-rated (CT) metering socket, not a self-contained service socket. Its line and load side terminals only accept 12 to 10 AWG wire, so it cannot take service entrance conductors. For a 200A self-contained residential service you need a 4-jaw, 200A rated socket instead. Use the UC1299-RL where current transformers do the measuring and the socket only carries instrument-level current.
2) Does this Milbank meter socket include a main breaker or disconnect?
No breaker and no disconnect. The UC1299-RL is a meter socket only, with zero main breakers and no receptacles in the enclosure. Any overcurrent protection or service disconnect has to be provided in separate gear downstream.
3) Can this Milbank ringless socket be mounted outdoors on an exterior wall?
Yes. It is a surface mount enclosure in G90 galvanized steel with a powder coat finish, carrying a Type 3R rating for rain, sleet and ice, and it is UL Listed. Type 3R is an outdoor rating, not a washdown or dust-tight one, so avoid locations subject to hose spray or heavy airborne dust.
4) What is the difference between the standard UC1299-RL and the UC1299-RL-ALT version?
Two versions are sold. UC1299-RL is the standard build; UC1299-RL-ALT is the Alliant Energy utility-approved variant. Order to match your serving utility's approved equipment list, since utilities will refuse to set a meter in a can that is not on their list.
5) What wire size do the terminals on the Milbank UC1299-RL accept?
Single mechanical terminals rated 12 to 10 AWG on both line and load side. That is CT secondary wiring territory. If your conductors are larger than 10 AWG, this socket is the wrong can for the job.
6) What does the 6 terminal ringless configuration on this Milbank socket mean for the meter I install?
Six jaws in a single meter position, wired single phase at 600V AC, 60 Hz. Ringless means the cover clamps over the socket rim rather than using a sealing ring, so you need a ringless-style meter cover and the utility seals the cover screw. Six terminals is the standard jaw count for transformer-rated single-phase metering, where separate current and potential connections are brought in.
7) How big is the Milbank UC1299-RL enclosure and how does the cable come in?
The enclosure measures 3.313 x 8 x 14 inches (L x W x H). Cable entry can be overhead or underground, and it ships with a small hub opening closing plate, so if you are running overhead you fit a hub sized to that small opening. Equipment grounding is through a ground lug in the can.
8) What does the auto bypass on this Milbank socket actually do for meter changes?
The auto bypass provision lets the load stay energized while the meter is pulled, so a meter swap or test does not drop the customer. For a property manager metering tenants, that means no outage notice for a routine meter exchange. The bypass is automatic, engaging as the meter is removed rather than needing a separate manual lever operation.
9) Is the Milbank UC1299-RL suitable for a 480V three phase metering installation?
Voltage is covered, phase is not. The socket is rated 600 volts AC, so 480V is within rating, but it is wired single phase with six jaws. A three phase transformer-rated installation needs a 13-jaw three phase socket instead.
10) What insulation is used behind the jaws on this Milbank meter socket?
Glass polyester supports the jaw assembly, which is the standard thermoset insulating base in utility metering cans and holds up to heat and tracking better than a plain thermoplastic block.
