Milbank UC5732-XL – Frequently Asked Questions

1) Will a Milbank UC5732-XL 15 terminal meter socket work on a 3 phase 600V service?
That's exactly what the UC5732-XL is built for. It's rated 600 volts AC, 3 phase, 60 Hertz, with 15 jaws and a single meter position. The 20 continuous ampere rating is the socket's own continuous current rating, which is why this is a CT-family device (product family code CT20): it's metered through current transformers rather than carrying full service current across the jaws. If you're looking for a socket that carries the full load directly, this is not it.
2) What wire size lands in the Milbank UC5732-XL meter socket terminals?
12 to 10 AWG, on both the line side and the load side, into single mechanical terminals. That is CT secondary wiring size, not service conductor size, so don't plan on landing service entrance cable here. Equipment grounding is a ground lug.
3) Can the UC5732-XL ringless meter socket be mounted outdoors?
Yes. It's UL Listed and carries a Type 3R rating, which covers outdoor use against rain and falling debris. The enclosure is G90 galvanized steel with a powder coat finish, and it surface mounts to a wall or backboard.
4) Does the Milbank UC5732-XL have a meter bypass or a main breaker?
Neither. The UC5732-XL is a no-bypass socket with no main breaker and no receptacles, so pulling the meter interrupts metering with no lever bypass to hold service. If your utility requires a bypass provision, or you need overcurrent protection integral to the socket, you need a different Milbank socket, not this one.
5) What does ringless mean on a meter socket, and does my utility allow it?
Ringless means the cover itself seals over the meter instead of a separate sealing ring clamping the meter to the socket. The UC5732-XL is a ringless design, and whether that is accepted is decided by the serving utility, not the code book. Utilities publish a service handbook that specifies ring type or ringless for their territory. Check that before ordering, because the two are not interchangeable in the field.
6) Can I bring conduit in overhead or does the UC5732-XL require underground service?
Either works. Cable entry is rated for overhead or underground, and the socket ships with a small closing plate for the hub opening. That closing plate is what you leave in place for underground entry from the bottom; for an overhead feed you swap it for the correct hub for your conduit size and utility spec. The hub is a separate item.
7) Is a 15 jaw socket the same as a 7 jaw or 13 jaw meter socket?
No, and they are not interchangeable. Jaw count follows the meter form the utility assigns. The UC5732-XL is a 15 terminal socket for a single meter position on a 3 phase 600V system, wired as a CT installation with 12-10 AWG conductors. A 7 jaw socket takes a different meter entirely. Confirm the meter form your utility is setting before you buy the socket, because the meter has to match the jaw configuration.
8) How much wall space does the Milbank UC5732-XL meter socket need?
Plan on 3.313 x 8 x 14 inches (L x W x H) for the enclosure itself. It surface mounts, so you also need working clearance in front per your local code and enough room above or below for the service entry, depending on whether you're coming in overhead or underground.
9) Which Milbank part number do I order for a 15 jaw ringless CT rated socket with a small closing plate?
Milbank UC5732-XL. That's the 15 terminal ringless socket, 3 phase, 600V, 20 continuous amp, Type 3R, with the small closing plate. The closing plate size matters when you're matching an existing installation, because a large closing plate socket takes a different hub range.
10) Will the UC5732-XL hold up in a coastal or wash-down environment?
The enclosure is G90 galvanized steel with a powder coat finish, rated Type 3R. Type 3R covers rain, sleet and falling dirt for outdoor use, but it is not a wash-down or hosedown rating and it is not sealed against windblown dust. For a corrosive coastal exposure or a plant area that gets pressure washed, look at a stainless or Type 4X socket instead.
11) What keeps the meter jaws isolated inside the Milbank UC5732-XL socket?
Glass polyester. The jaw block is molded glass polyester, which is what holds the 600V rating and the phase to phase separation on a 3 phase socket. It's the standard insulating material for commercial metering enclosures and it will not track or carbonize the way a lower grade phenolic can in a damp outdoor cabinet.
