Milbank U6115-X-2/200-K7L – Frequently Asked Questions

1) Will a Milbank U6115-X-2/200-K7L meter socket work on a 480V 3-phase service?
Yes. The U6115-X-2/200-K7L is a 7 terminal ringless socket rated up to 480 volts AC, 3 phase, 60 Hz. Seven jaws is the 3-phase 4-wire configuration, so it belongs on a 480/277V wye service, not on a 3-wire delta and not on a single-phase 120/240 service (those use 4 or 5 jaw sockets). Check the utility's meter jaw requirement before ordering, since the jaw count has to match what they will set.
2) Does the 320 amp rating on this Milbank meter socket mean I get a 320 amp main breaker?
No, and this trips people up. The socket carries a 320 continuous ampere rating, but the overcurrent protection is two 200 ampere main breakers, not one 320. You get two separate 200A feeders out of the enclosure. If the job needs a single 320A or 400A disconnect feeding one panel, this is the wrong unit; you want a meter main with a single main breaker of that size.
3) What size service conductors can I land in the Milbank U6115-X-2/200-K7L?
The line side lugs take 4 AWG through 600 kcmil single conductor, or two conductors per phase from 1/0 AWG through 250 kcmil if you are running parallel sets. They are single mechanical terminals. Equipment grounding is handled by a 2 barrel ground lug. That range covers a full 320A copper or aluminum service entrance without needing aftermarket lugs.
4) Can this Milbank meter main be mounted outdoors on an exterior wall?
Yes. It is a UL Listed Type 3R enclosure, which is the rainproof rating for outdoor service equipment, built from G90 galvanized steel with a powder coat finish for corrosion resistance. It is a surface mount unit, so it bolts to the wall face rather than recessing into the wall. If the architect called for a flush installation, this is not the enclosure for it.
5) Does the Milbank U6115-X-2/200-K7L have a bypass so the meter can be pulled without killing the building?
It has a lever bypass. The utility or a qualified tech throws the lever to shunt the jaws, and the meter can be pulled and swapped while the load stays energized. That is why this unit gets specified on occupied commercial buildings and multi-tenant properties where an outage for a meter change is not acceptable. It is a ringless socket, so the meter is retained by a sealing cover rather than a locking ring.
6) How many tenants or meters can I serve with this Milbank meter main?
One. It is a single meter position socket, so it meters one service. The two 200A main breakers split the load downstream of that single meter, they do not create two metered accounts. For a building where each tenant needs its own billed meter, you need a multi-position meter stack, not this unit. There are also no receptacles built into the enclosure.
7) Can I feed this Milbank meter socket from an underground service, or does it have to be an overhead drop?
Either one. Cable entry is rated for overhead or underground, so it works with a mast and riser or with a lateral coming up from below. A large hub closing plate is provided on top, so if you are going underground you leave the plate in place, and if you are going overhead you punch it for the hub your utility requires. The hub itself is a separate item sized to your conduit.
8) Ringless or ring type meter socket, which one does my utility want?
The utility decides, and getting it wrong means the socket gets rejected at inspection. The U6115-X-2/200-K7L is the ringless version: the cover slides over the meter and seals at the socket, with no separate locking ring. Many utilities standardize on ringless for exactly that reason, others require ring type. Confirm with the serving utility's meter installation standard before you order, because the two are not field convertible.
9) What are the two 200 amp breakers in this Milbank unit actually used for on a job?
They let you split a single 480V 3-phase service into two independently protected feeders straight out of the meter enclosure, so you can feed two distribution panels, or a building panel plus a large piece of equipment like a chiller or a shop feed, without an extra distribution section. Each side is limited to 200 amps. If one of your two loads will draw more than 200 amps, this arrangement will not carry it.
10) What exact part number do I give my distributor for the Milbank 7 terminal 480V meter main with two 200A breakers?
Order it as Milbank U6115-X-2/200-K7L. The number reads out as the 7 terminal ringless socket with a large closing plate, two 200 ampere mains, 480 volt rating, and single locking connectors for 4 AWG to 600 kcmil. Milbank groups it in the MTMN meter main family. Its UNSPSC code is 39121102 if your procurement system needs one.
11) Is the Milbank U6115-X-2/200-K7L suitable for a coastal or industrial site?
The enclosure is G90 galvanized steel with a powder coat finish over it, which is the standard corrosion package for outdoor service equipment, and the internal insulating barriers are glass polyester. Combined with the Type 3R rating it handles normal outdoor weather exposure. For heavy salt spray or corrosive process environments, a facility spec often calls for stainless or a higher NEMA type, so check what the electrical spec requires.
