Milbank U3885-X-BLG – Frequently Asked Questions

1) Will the Milbank U3885-X-BLG meter socket work for a 320 amp single phase residential or commercial service?
Yes. The Milbank U3885-X-BLG is rated 320 continuous amperes, single phase, 600V AC at 60 Hz, with one meter position and 5 jaws, which is the standard self-contained 320A (400A class) single phase socket arrangement. There is no main breaker in the enclosure, so overcurrent protection has to live downstream in the panel or in a separate disconnect.
2) Is this meter socket set up for underground service entrance or overhead?
Cable entry on the U3885-X-BLG is underground with a side wireway, and it ships with a large hub closing plate covering the top hub opening. For an overhead drop you would need to open that hub and fit a weatherhead hub of the correct trade size instead of using the closing plate.
3) What does the lever bypass on a 320A Milbank socket actually do for the utility?
The lever bypass lets a meter be pulled and reinstalled without dropping power to the load, so service stays live during meter change-out or testing. Many utilities require a bypass on 320A class self-contained sockets; if your utility spec calls for no bypass or a horn bypass, this is not the right model.
4) Can this meter socket be installed outdoors on an exterior wall?
Yes. The enclosure is UL Listed and Type 3R rated, which covers outdoor exposure to rain, sleet and ice, and the shell is G90 galvanized steel with a powder coat finish for corrosion resistance. Type 3R is not washdown or dust-tight, so it is not the choice for a hose-down or heavy dust environment.
5) How much wall space do I need for this Milbank 320 amp socket, and how does it mount?
It is a surface mount enclosure measuring 5.75L x 16W x 30H inches, so plan on a 16 inch wide by 30 inch tall footprint on the wall with about 5.75 inches of projection, plus working clearance in front per code.
6) Does the Milbank U3885-X-BLG ringless socket need a separate ring, and what does ringless mean for the meter?
No ring is used. A ringless socket takes a lift-off cover that retains the meter instead of a sealing ring clamped around the rim, which is what most utilities in ringless territory require. Check which style your utility accepts before ordering, because a ringless socket will not take a ring-type meter cover.
7) How do I lock and seal this socket against tampering?
The socket comes with a 7/8 inch knockout and an angle bracket for a barrel lock, so a utility barrel lock drops straight in without drilling. The barrel lock itself is not part of the socket.
8) What size conductors and ground does this 320A socket accept, and is a ground lug included?
Line and load connections are single mechanical terminals, and an equipment ground lug is provided in the enclosure. Insulation on the socket base is glass polyester. Size your service conductors to the 320 continuous ampere rating and your local code.
9) Can I meter two units or tenants with this Milbank socket?
No. It is a one position, single meter socket with 5 jaws. For two or more tenants you need a multi-position meter stack or separate sockets, one per metered service.
10) Does this socket include a main breaker or any receptacles?
Neither. The U3885-X-BLG is a meter socket only, with zero main breakers and zero receptacles. If you need combined metering and service disconnect, specify a meter-main combination instead of this socket.
11) What is the exact Milbank part number to order for this 320A lever bypass socket?
Order Milbank U3885-X-BLG. It falls in Milbank product family code 5T32, the 5 terminal 320A group.
