Milbank U3584-O-200 – Frequently Asked Questions

1) What's the difference between the 4-jaw and 7-jaw version of the Milbank U358 200A meter socket with main breaker?
The jaw count has to match what your utility requires for the service being metered. Milbank offers this 200A ring type socket as U3584-O-200 with the 4 terminal (jaw) configuration and U3587-O-200 with the 7 terminal configuration. Everything else is the same between them: one 200 amp main breaker, underground entry, plain top, surface mount. Call your serving utility before you order, since the jaw count is their spec, not a preference.
2) Can I use this Milbank meter socket for an overhead service drop?
No. The U358-O-200 is built for underground entry and ships with a plain top, meaning there is no hub opening for a service mast or weatherhead conduit. For an overhead drop you want an overhead-entry socket with a hub opening or hub closing plate provision. Ordering this one for a mast service means cutting the enclosure, which most utilities will reject at inspection.
3) What size service conductors will land in this 200 amp Milbank meter socket with main?
Line side lay-in terminals take 6 AWG through 350 kcmil, and the load side takes 1 AWG through 300 kcmil. That covers the usual 200 amp service builds, including 4/0 aluminum on the line side and 4/0 aluminum or 3/0 copper feeding the panel. The lay-in design means you drop the conductor in rather than threading it through a hole, which matters when you are working 350 kcmil in a trench-fed can.
4) Does this Milbank socket work as the service disconnect, or do I still need a separate main?
It serves as the disconnect. The U358-O-200 carries one 200 ampere main breaker built into the meter can, which gives you overcurrent protection and a service disconnecting means at the meter. That lets you run the feeder to a main-lug-only panel inside instead of buying a separate outdoor disconnect. Rated 200 continuous amperes, up to 240 volts AC, 60 Hz.
5) Will a ring type meter socket work if my utility uses ringless covers?
No. This Milbank unit is a ring type socket, meaning the meter is retained by a sealing ring around the meter glass. Ringless utilities use a full hinged cover that drops over the meter, and the two covers are not interchangeable. Which style you need is set by the serving utility, not the installation, so check their approved equipment list first.
6) Can this Milbank meter socket be mounted outdoors on an exterior wall?
Yes. It is UL Listed with a Type 3R enclosure rating, which is the outdoor rain-tight classification utilities expect on a wall-mounted service. The can is G90 galvanized steel with a powder coat finish, and it is a surface mount unit, so it bolts flat to the wall rather than recessing into it.
7) How many meters does this Milbank socket serve, and can I use it on a duplex?
One meter position only, single tenant. For a duplex or any multi-family building where each unit is metered separately, you need a two-gang or multi-position meter stack instead. There are also no auxiliary receptacles in this unit, so if the job calls for a house-power outlet at the meter, that gets added elsewhere.
8) How is the grounding handled in this Milbank meter socket with main breaker?
It comes with a 2 barrel ground lug for bonding the grounding electrode conductor and equipment ground. Internal insulation is glass polyester, which is what isolates the live jaw assembly from the galvanized can.
9) How wide is the Milbank U358 200 amp meter socket for wall layout?
The published footprint is 14.125 inches wide by 5.5 inches deep, which is the number to work with when you are spacing it off a corner, a gas meter, or a downspout. Being surface mount, the full depth stands off the wall face.
