Milbank USS3914-O – Frequently Asked Questions

1) Will the Milbank USS3914-O work for an overhead service drop?
No. The USS3914-O is built for underground cable entry with a plain top, meaning there is no hub opening for an overhead mast or weatherhead conduit. If your service comes in overhead, you need a socket with a hub or hub opening top instead. For an underground lateral coming up into the bottom of the can, this is the right configuration.
2) Is a 4 terminal ringless meter socket the right one for a 200A single phase residential service?
For a standard 120/240V single phase, 3-wire residential or light commercial service, 4 jaws is the normal configuration, and the USS3914-O is rated 200 continuous amperes at 600VAC, 60 Hz, single phase. Seven-jaw sockets are for three phase metering, and five-jaw sockets are used for 120/208V network services. Check with your serving utility first, since the number of jaws and whether they accept ringless or ring-type is dictated by their approved meter equipment list.
3) Does this Milbank meter socket include a main breaker or a disconnect?
No main breaker and no bypass provision. The USS3914-O is a meter socket only, single meter position, so you still need a separate main disconnect or panel downstream. If your jurisdiction requires a service disconnect at the meter, order a meter main combination instead of this can.
4) What size service conductors will the lay-in terminals accept?
Both line and load side lugs take 6 AWG through 350 kcmil, and they are lay-in style so the conductor drops in rather than threading through a closed barrel. That range covers the usual 4/0 aluminum or 2/0 copper used for a 200A dwelling service with room to spare for a parallel-free 350 kcmil run.
5) Can this Milbank socket be installed outdoors, and is it UL Listed?
Yes, it is UL Listed and carries a Type 3R enclosure rating, which is the outdoor rating for protection against falling rain, sleet and ice formation. Type 3R is not a hose-down or dust-tight rating, so it belongs on an exterior wall, not in a pressure-wash bay interior or a dusty process area.
6) What is the difference between a ringless and a ring-type meter socket, and which does my utility want?
A ringless socket like the USS3914-O uses a full cover that slides over the meter and is sealed at the socket, with no separate sealing ring clamping the meter glass. Ring-type uses a locking ring around the meter rim. They are not interchangeable, and utilities specify one or the other in their service handbook, so confirm which your serving utility accepts before ordering. The jaw count (4 terminal here) has to match their meter as well.
7) Is a stainless steel meter socket worth it over painted steel in a coastal or wash-down location?
The USS3914-O is unpainted 304 stainless, which is why it gets specified near salt air, agricultural ammonia, car washes and other places where a galvanized or painted can starts rusting at the seams within a few years. There is no paint film to chip or scratch during install, so field damage does not become a corrosion start point. For a dry inland residential wall it is more can than you need.
8) Is there a grounding provision in the can, or do I have to add a lug?
A ground lug is factory installed for the equipment grounding conductor, so you do not need to field-drill and add a separate lug kit. Bonding of the neutral at the service point still follows your local utility and inspector's requirement.
9) What is the insulation inside this meter socket made of?
Glass polyester supports the jaws and terminals, a thermoset material chosen for dielectric strength and dimensional stability at the temperatures a 200A socket sees under sustained load. It will not soften or creep the way an unfilled thermoplastic block can.
