Milbank U5767-X-200-CB-BL – Frequently Asked Questions

1) Will a Milbank U5767 meter socket work on a 480V three-phase service?
The U5767 ringless meter socket is built for 3-phase service rated up to 480 volts AC at 60 Hz, with a 7 terminal jaw configuration. Seven jaws is the standard count for a 3-phase 4-wire meter, so this is the socket for a 480/277V wye service, not for single phase. If the building is single phase 120/240, this is the wrong socket and you want a 4 jaw single phase unit instead.
2) What size conductors can I land in a Milbank 200A ringless meter socket?
Load side terminals on the U5767 take 6 AWG through 350 kcmil, single mechanical lugs. That covers the usual 200 amp copper and aluminum feeder sizes, including parallel-free 250 and 350 kcmil aluminum runs. Equipment grounding is handled by two barrel ground lugs in the can. The socket is rated 200 continuous amperes.
3) Can the meter be pulled on a Milbank U5767 without killing power to the building?
Yes, the U5767 carries a lever bypass. Throwing the lever keeps the load energized while the meter is out, which is what a utility or a service electrician needs for a meter swap or test without dropping the tenant. It is a single meter position socket, so the bypass covers the whole service.
4) What is the difference between the U5767-X-200-CB and the U5767-X-200-TF?
Both are 200A 480V cold sequence ringless sockets. The CB version comes with a main breaker as the service disconnect; the TF version uses a main pullout instead. Pick the breaker if you want a resettable disconnect the building staff can operate, the pullout if the utility or local practice calls for a fused pullout style disconnect. Either way there is one main device in the can.
5) Which Milbank U5767 do I order if the utility requires a barrel lock?
Order the U5767-X-200-CB-BL, which ships with the barrel lock bracket. The base socket is already punched for it, with a 9/16 inch knockout and an angle bracket provision for a barrel lock, so the BL version simply comes with the bracket fitted. There is also a U5767-X-200-CB-BL-NE variant built to New England utility requirements, and a U5767-X-200-CB-AMS for Ameren territory.
6) Can a Milbank U5767 meter socket be mounted outdoors on an exterior wall?
Type 3R rated and UL Listed, so the U5767 is built for outdoor wall mounting. The enclosure is G90 galvanized steel with a powder coat finish, and it is surface mount, meaning it hangs on the face of the wall rather than sitting flush in it. Plan for 43 inches of height and 13 inches of width on the wall.
7) Does the Milbank U5767 handle an underground service lateral, or is it overhead only?
Both. The U5767 accepts overhead or underground cable entry. For an overhead drop through the top you use a hub, and the socket ships with a large closing plate covering the hub opening when you are coming in from below on an underground lateral. The hub itself is sized to the raceway and ordered separately.
8) What does ringless mean on a Milbank meter socket, and does my utility allow it?
Ringless means there is no sealing ring around the meter; a hinged or lift-off cover holds the meter in place and the utility seals the cover. Ringed sockets clamp the meter with a separate ring. Utilities specify one or the other and they are not interchangeable in the field, so confirm which style your serving utility requires before ordering. The U5767 is ringless, and specific utility versions exist for Ameren and New England territories.
9) Is the Milbank U5767 a cold sequence socket, and what does that mean for the electrician?
All five U5767-X-200 configurations are 480V cold sequence. Cold sequence puts the disconnect ahead of the meter, so the meter socket jaws are dead once the main is opened. Hot sequence is the reverse and leaves the socket energized with the disconnect off. Some utilities mandate cold sequence for 480V services specifically for that reason, and this socket is built with one main device in the can to do it.
10) Will one Milbank U5767 meter socket serve more than one tenant?
No. The U5767 is a single meter position socket with no receptacles, so it meters one service. For a multi-tenant building where each unit needs its own meter, you need a multi-position meter stack or gang socket, not this can. Where the U5767 fits a multi-tenant property is metering the house or common-area service.
11) What UNSPSC code should I use to requisition a Milbank U5767 meter socket?
UNSPSC 39121102 covers the U5767 ringless meter socket. That is the code to drop into a government, healthcare, or institutional purchasing system so the line item classifies correctly against electrical distribution hardware.
