Milbank UC7461-WL-171 – Frequently Asked Questions

1) Will the Milbank UC7461 meter socket work on a 3 phase 600V service?
That's exactly what the UC7461 is built for: 3 phase, 600 volts AC, 60 hertz, with a 13 terminal ring type jaw configuration. The 13 terminal arrangement is what a 3 phase 4 wire meter installation needs, and it gives you the connection points for the test switch as well. One meter position per enclosure.
2) Why is this Milbank meter socket only rated 20 amps when the service is much larger?
Because it's a CT rated socket, not a self contained one. The UC7461 carries a 20 continuous ampere rating and a CT20 product family code, meaning it sits downstream of current transformers that do the actual load metering. The 20 amps is the secondary current from the CTs, not the service size. If you're metering a service directly at full load current, this is the wrong socket and you want a self contained socket rated for that service amperage instead.
3) Which hub size should I order on the Milbank UC7461 meter socket?
Match it to the conduit carrying your CT secondary leads. Three choices: a small hub opening on UC7461-RL and UC7461-RL-131, a 1 inch hub on UC7461-WL-171, and a 1.25 inch hub on UC7461-YL-TGE-DES. The socket accepts overhead or underground cable entry either way, so the hub selection is about conduit trade size, not service direction.
4) Can the Milbank UC7461 meter socket be mounted outdoors?
Yes. It's UL Listed and Type 3R rated, so it's suited to outdoor surface mounting where rain and falling debris are the concern. Enclosure is G90 galvanized steel with a powder coat finish. Type 3R is not a washdown or dust tight rating, so for interior process areas or hosedown environments you'd specify a higher enclosure type.
5) What is the difference between the test switch provision and test switch prewired options on the Milbank UC7461?
Provision means the socket is built to accept a test switch but ships without one, so you supply and wire the switch yourself. Prewired means the test switch comes installed and wired to the meter terminals, so the can lands on the wall ready for the utility. Four builds are offered: UC7461-RL with small hub opening and test switch provision, UC7461-RL-131 with small hub opening and test switch prewired, UC7461-WL-171 with a 1 inch hub and test switch prewired, and UC7461-YL-TGE-DES with a 1.25 inch hub, test switch installed, and Tucson Gas and Electric specification.
6) Does the Milbank UC7461 meter socket include a main breaker or bypass?
No on both. The UC7461 is a straight metering enclosure: no main breaker, no bypass provision, no receptacles. Disconnecting means is handled upstream or downstream in separate gear, and because there's no lever bypass, pulling the meter on a live installation is done through the test switch rather than at the socket. If your utility requires a bypass at the meter, this build won't satisfy it.
7) How much wall space do I need for the Milbank UC7461 meter socket?
Enclosure measures 4.125 inches deep by 12 inches wide by 20 inches high. It's a surface mount can, so plan on the full 20 inch height of clear wall plus working clearance in front per code for the utility and for anyone opening the test switch.
8) Is the Tucson Gas and Electric version of the Milbank UC7461 usable in other utility territories?
UC7461-YL-TGE-DES is built to a Tucson Gas and Electric specification with a 1.25 inch hub and the test switch installed. Meter socket acceptance is set by the serving utility, so outside that territory order against your own utility's approved list. For a general 13 terminal CT rated socket the plain builds are UC7461-RL, UC7461-RL-131, and UC7461-WL-171.
9) What else do I need to complete a CT metering installation with the Milbank UC7461?
The socket is one piece of the assembly. You'll still need the current transformers and a CT cabinet or enclosure sized to the service, the secondary conductors in 12 to 10 AWG to land in the socket terminals, conduit matched to the hub you ordered, and a test switch if you order the UC7461-RL provision build rather than one of the prewired versions. No breaker is in the can, so overcurrent protection lives in separate gear.
10) Is the Milbank UC7461 a ringless or ring type meter socket?
Ring type. The meter is retained by a sealing ring around the cover opening, which is the style many utilities require for 13 terminal CT metering. If your utility spec calls for ringless, this socket does not meet it and you need a ringless bodied socket instead.
11) Will the Milbank UC7461 meter socket hold up on a coastal or exposed industrial site?
Enclosure is G90 galvanized steel with a powder coat finish, and internal insulation is glass polyester. G90 is a heavier zinc coating than standard galvanized sheet, which is what gives the can its corrosion resistance outdoors under the Type 3R rating. For heavy salt or chemical exposure, a stainless enclosure is the usual step up.
