Milbank U612X-BL 125A 240V Multi-Position Ringless Meter Socket with Type 3R Enclosure

The Milbank U612X-BL is a ringless meter socket designed for condo-style, multi-position service entrances, available in 3-, 4-, and 5-position configurations rated 125A continuous at up to 240V AC, 1-phase, 60 Hz. Housed in a Type 3R enclosure built from G90 galvanized steel with a powder coat finish, this Milbank meter socket is suited for surface-mount indoor or outdoor multi-unit residential service entrances. The common area meter position includes a lever bypass while residential positions have none, and a 9/16-inch knockout with angle bracket provides barrel lock provision for tamper resistance. UL Listed for code-compliant, utility-accepted installation.

G90 galvanized steel with a powder coat finish keeps the Type 3R enclosure performing in exposed outdoor locations without the corrosion issues common on lesser-grade housings, while the ringless, multi-position layout with lever bypass on the common area meter and a 9/16-inch barrel lock knockout simplifies metering and tamper resistance across condo and apartment service entrance installations.

Milbank U6123-X-BL – Frequently Asked Questions

1) How many meter positions does the Milbank U6123, U6124, and U6125 condo meter socket come in?
Three, four, and five position versions. U6123-X-BL is the 3 position, U6124-X-BL the 4 position, and U6125-X-BL the 5 position. Pick the count to cover your units plus the house meter, because the common area position is one of the positions, not an extra. Every position is 125A continuous at up to 240V AC, single phase, 60 Hz.
2) Does every meter position on the Milbank U612X-BL condo socket have a bypass?
No. Lever bypass is on the common area meter position only; the residential positions have no bypass. That means the utility can pull the house meter without dropping power to common area loads (hall lights, elevators, pumps), but pulling a tenant meter kills that unit. If your utility requires bypass on every tenant position, this is the wrong socket.
3) What size conductors can I land in a Milbank 125A ringless condo meter socket?
Line side terminals take 6 AWG through 350 kcmil, load side 1 AWG through 300 kcmil, on single mechanical lugs. That line range is wide enough for a service lateral sized well above the 125A rating, which is normal on multi-unit taps. There is a ground lug for the equipment ground.
4) Can a Milbank U6123 ringless meter socket be mounted outdoors on an exterior wall?
Yes. It is a Type 3R enclosure, UL Listed, built from G90 galvanized steel with a powder coat finish, so rain, sleet and external ice are within its rating. It is a surface mount unit, so it hangs on the wall face rather than recessing into the framing. Flush mounting it is not an option.
5) Will the Milbank U612X-BL condo socket accept the utility barrel lock our power company requires?
Yes. A 9/16 inch knockout and an angle bracket are built in for a barrel lock, which is the standard tamper provision utilities ask for on ringless equipment. The lock itself is supplied by the utility, not with the socket.
6) How many jaws does the Milbank U612X-BL socket have, and will it take the utility's meter?
Four terminal jaws per position, single phase, up to 240V. That is the standard configuration for residential single phase 3 wire metering, which is what a condo or apartment unit gets. A 5 jaw or 7 jaw network meter will not seat in it, so confirm the utility is issuing a 4 jaw meter before you set the can.
7) Does the Milbank U6125 condo meter socket come with main breakers installed?
No. It has a breaker provision, meaning the space and mounting are there but the breakers are ordered separately. Budget the branch devices for each position on top of the socket itself, and match them to what the utility and the AHJ will accept for the service.
8) Can I use a 125A Milbank condo meter socket on a 200A service?
No. Each position is rated 125 continuous amperes at up to 240V AC, single phase, so it cannot be used where a position needs 200A. Step up to a 200A rated multi-position socket instead. The 125A rating is per position and suits standard multi-unit residential loads.
9) Is a ringless meter socket the right choice, or do I need a ring type?
Ringless is what the utility dictates, not the installer. On a ringless socket like the Milbank U612X-BL there is no locking ring around the meter; a hinged cover over the meter face is secured instead, which is why the barrel lock provision matters here. Ring type sockets clamp the meter with a sealing ring. Call the serving utility before you order, because they will reject the wrong style on inspection and the two are not interchangeable in the field.
10) Can I feed a Milbank U6124 meter socket from an underground lateral instead of an overhead drop?
Either one. The socket is configured for overhead or underground cable entry, so the same unit works for a riser and weatherhead or for a lateral coming up from below. A large hub closing plate is provided on the top for when you are coming in underground and do not need a hub opening.
11) How much wall space do I need for a Milbank multi-position condo meter socket?
The unit measures 30.5 inches for product height and 5.969 inches for product length. Plan the wall run and working clearance around that footprint, and remember it stands proud of the wall since it is surface mounted.
