Milbank UC2427-XL – Frequently Asked Questions

1) Is the Milbank UC 2-Position meter socket a self-contained 200A socket or a transformer-rated one?
It's transformer rated. The UC 2-Position carries a 20 continuous ampere rating at 600V AC, 60 Hz, which is instrument-transformer metering territory, not self-contained service. The line and load side terminals only accept 12 to 10 AWG, so full service conductors never land in this can. Load current is carried by the CTs; this socket only sees the metering secondary. If you're metering a service directly with the service conductors, this is the wrong socket.
2) Does the Milbank UC 2-Position meter socket come with a main breaker or bypass?
No on both counts. The UC 2-Position is a metering enclosure only: no main breaker, zero breaker spaces, and no bypass provision. Any disconnect or overcurrent protection has to be a separate device ahead of or behind the socket. If your utility requires a lever bypass on the meter position, this one won't satisfy it.
3) How do I pick between the 8 terminal and 13 terminal Milbank UC 2-Position sockets?
Terminal count follows the meter form the utility specifies. The 2-position UC comes as 8 terminal (UC2427-XL, ring type) and 13 terminal (UC2428-XL ring type for Wisconsin Public Service, UC3453-XL ringless). Get the terminal count and ring/ringless requirement off the utility's metering standard before you order; the jaw arrangement is not field-changeable.
4) Ring type versus ringless meter socket - which Milbank UC 2-Position do I need?
That is a utility call, not a preference. Ring type covers seal with a sealing ring around the meter; ringless uses a full cover that seals over the meter. UC2427-XL and UC2428-XL are ring type; UC3453-XL is ringless. Utilities publish one or the other in their service handbook, and they will refuse to set a meter in the wrong style.
5) What size wire lands in the Milbank UC 2-Position and is there a ground lug?
Both line and load side terminals take 12 to 10 AWG on single mechanical terminals, which is sized for CT secondary and voltage leads, not service conductors. An equipment ground lug is provided in the can for bonding. If the metering leads your utility runs are outside 12 to 10 AWG, this socket won't terminate them.
6) Can the Milbank UC 2-Position meter socket be installed outdoors?
Yes. It's a UL Listed Type 3R enclosure built from G90 galvanized steel with a powder coat finish, which is the standard rain-tight rating for outdoor wall-mounted service equipment. It surface mounts to the wall or structure; there's no flush or recessed version.
7) Will the Milbank UC 2-Position work for an underground service lateral, or is it overhead only?
Either. Cable entry is rated for overhead or underground, so the same socket serves a riser feed or a lateral coming up from below. It ships with a small closing plate for the hub opening, so if you're feeding overhead through a hub you supply the hub separately and pull the plate; underground you leave the closing plate in place and enter from the bottom.
8) What does 2 position mean on the Milbank UC meter socket?
The enclosure carries two positions, which gives the utility a separate test switch position next to the meter. Pick 2 position where the utility's standard calls for that layout. If the test switch mounts inside the can behind a single cover, the single-position UC-XL deep shell (UC3887-XL, UC3889-XL) is listed separately.
9) Is the Milbank UC 2-Position suitable for a 480Y/277V three-phase commercial service?
The socket itself is rated 600 volts AC, 60 Hz, three phase, so 480Y/277 is within its voltage rating. Understand what you're buying though: it's a CT-rated metering can at 20 amps continuous, so the actual service current runs through separate current transformers and switchgear. It is not the service disconnect and holds no breaker.
10) Is the Wisconsin Public Service version of the Milbank UC 2-Position usable in other utility territories?
UC2428-XL is a 13 terminal ring type socket built to a Wisconsin Public Service specification. Utility-specific sockets are approved against that utility's metering standard, so ordering it outside WPS territory risks a rejected inspection even though the electrical ratings match. Outside WPS, the generic 13 terminal 2-position option is the UC3453-XL ringless.
11) Does the Milbank UC 2-Position have receptacles or space for auxiliary devices?
No receptacles and no breaker spaces. The UC 2-Position is strictly a metering enclosure with glass polyester insulation supporting the meter jaws and provision for a test switch. Anything else on the job, disconnects, auxiliary power, panels, goes in separate equipment.
