Milbank U3523-XL-K1 – Frequently Asked Questions

1) Is the Milbank U352-XL meter socket a single-meter socket or a multi-position gang?
It's a multi-position horizontal gang socket, sold in 2, 3, 4, and 5 position configurations (MPNs U3522-XL-K1, U3523-XL-K1, U3524-XL-K2, and U3525-XL-K2). Each position carries its own 125 continuous ampere ring-type meter socket, so a 4-position unit meters four separate tenants off one enclosure. That's what makes it a fit for multi-unit residential and small commercial buildings where each unit needs its own utility meter rather than one house meter.
2) Does the Milbank U352-XL gang socket have main breakers or disconnects built in?
No. The U352-XL series ships with no main breaker and no bypass provision, so it's a metering enclosure only. You'll need to provide overcurrent protection and any service disconnect separately, either upstream ahead of the socket or in tenant panels downstream. If your utility or inspector requires a disconnect at the meter, this is not the unit for that job, look at a meter-main combination instead.
3) What size wire can I land on the load side of a Milbank 125A gang meter socket?
Load side terminals take 6 AWG through 2/0 AWG. That covers the usual copper and aluminum feeders for a 125 amp tenant service, so a 2/0 aluminum or 1/0 copper run to each unit panel lands directly without adapters or splice blocks. Anything larger than 2/0 will not fit the lug.
4) Will a ring-type meter socket work in my area, or do I need a ringless one?
That's a utility call, not a code call. Ring-type sockets like the U352-XL use a sealing ring to lock the meter to the socket rim, and many utilities specify ring-type exclusively while others require ringless with a hinged cover. Check the serving utility's approved meter equipment list before ordering, because the two are not interchangeable and a utility will refuse to set a meter on the wrong style.
5) For a 4-plex, do I order one 4-position gang or four separate meter sockets?
One 4-position gang, model U3524-XL-K2, handles all four tenants in a single enclosure with 125 amps per position. It saves you three separate wall penetrations and three separate mounting jobs, and most utilities prefer a single gang assembly at the service point on a small multi-family building. If the units are on separate walls or separate buildings, individual sockets are the right call instead. The same family runs 2, 3, and 5 position versions if the unit count is different.
6) Can I mount this Milbank gang meter socket outdoors on an exterior wall?
Yes. It's a Type 3R enclosure built from G90 galvanized steel with a powder coat finish, so it's rated for outdoor use against rain, sleet and ice, and the galvanizing is what keeps it from rusting out on a coastal or weather-exposed wall. Mounting is surface mount, so it fastens flat to the wall face rather than recessing into the framing.
7) Does this Milbank socket work for overhead service drops or only underground laterals?
Both. Cable entry is rated for overhead or underground, so the same enclosure serves a weatherhead drop from a pole or a lateral coming up from a pad transformer. A small hub closing plate is part of the unit, which is what you remove or replace with a hub when you bring conduit in from the top for an overhead feed.
8) How is the equipment ground made up in a Milbank ring-type gang meter socket?
Grounding is through a ground lug in the enclosure, so the equipment grounding conductor and the grounding electrode conductor land on that lug rather than on a factory-bonded bar with neutral terminations. Internal insulation is glass polyester, which is what isolates the live jaw assemblies from the steel can.
9) How much wall depth do I need to clear for a Milbank U352-XL gang meter socket?
The product length is 4.5 inches. Plan the mounting location and any adjacent obstructions around that figure, along with the working clearance in front of the meters your jurisdiction requires. Note the enclosure is surface mounted, so it sits proud of the wall rather than sunk into it.
