Milbank UC1300-RL – Frequently Asked Questions

1) Does the Milbank UC series 20A ring-type socket carry the service load, or is it only for CT secondary wiring?
It is a CT-rated meter socket, so the service conductors never pass through it. The 20 continuous amp rating and the 12-10 AWG line and load terminals are sized for current transformer secondary leads and potential leads only. The actual service current stays in the CT cabinet. If you need a socket that carries the full service, you want a self-contained 100A, 200A or 320A socket instead, not this one.
2) What is the difference between the terminal options 5, 6, 8 and 13 on the Milbank UC CT meter socket?
Terminal count is the only ordering choice, and it has to match the metering configuration your utility specifies. Four builds are offered: 5 terminal (UC1291-RL), 6 terminal (UC1300-RL), 8 terminal (UC7544-RL) and 13 terminal (UC7545-RL). Get the terminal count off the utility's metering spec sheet before you order, because the socket jaw arrangement has to match the meter the utility will set.
3) Can this Milbank CT meter socket be mounted outdoors on an exterior wall?
Yes. The enclosure is UL Listed and rated Type 3R, which is the outdoor rain-tight classification, and the body is G90 galvanized steel with a powder coat finish for corrosion resistance. It mounts to the surface of the wall or structure, and cable can come in overhead or underground.
4) Will the utility be able to change the meter without dropping power to the tenant?
Yes. The socket includes an auto bypass provision, which shorts the CT secondaries and maintains the circuit while the meter is pulled, so the load stays energized during a meter change or test. That is the main reason to spec this over a non-bypass CT socket on a building you cannot take offline.
5) Is this a ring type or ringless meter socket, and does that matter for my utility?
It is a ring type socket, meaning the meter is retained by a sealing ring rather than a removable ringless cover. Utilities specify one or the other and will not set a meter in the wrong style, so confirm the requirement with your serving utility before ordering. If they require ringless, this socket will not be accepted.
6) How much wall space do I need for the Milbank 20A ring-type CT socket?
Plan on a footprint of 3.313 x 8 x 14 inches, with 14 inches the height and 8 inches the width. It is a single meter position enclosure, so it is narrow enough to sit beside the CT cabinet on most service walls.
7) Is there a main breaker or disconnect in this Milbank meter socket?
No. This is a metering enclosure only, with no main breaker and no receptacles. Overcurrent protection and the service disconnect have to be provided separately, typically in the panel or the CT cabinet assembly downstream.
8) What voltage and frequency can the Milbank UC CT socket be used on?
It is rated 600 volts AC at 60 hertz, which covers standard 120/240V, 120/208V and 277/480V metering installations in North America.
9) How do the equipment ground and the conduit entry work on this Milbank CT socket?
Grounding is made up at a ground lug inside the enclosure. The top is furnished with a small hub opening closing plate, so you pick a hub sized for your conduit or leave the plate in place for underground entry from below. Terminals are single mechanical type, taking 12 to 10 AWG on both line and load sides.
10) I'm standardizing meter sockets across a multi-building property. Can I spec one part number for all of them?
Only if every opening uses the same metering configuration. The enclosure, the 600V 60Hz rating, the Type 3R construction and the single meter position are common across the range, but the terminal count varies by utility requirement: 5, 6, 8 or 13 terminal. Pull the terminal count for each service and order accordingly; the rest of the assembly is identical, so spares interchange within a given terminal count.
11) What is the insulation material inside this Milbank meter socket, and how does it hold up outdoors?
The internal insulating base is glass polyester, which is the standard dielectric barrier material for CT metering enclosures and tolerates the heat and moisture cycling of an exterior Type 3R installation. The outer shell is G90 galvanized steel with a powder coat finish.
