Milbank U1897-X-WI – Frequently Asked Questions

1) Will the Milbank U1897-X-WI meter socket be accepted by Wisconsin utilities?
The U1897-X-WI is built to the Wisconsin area utility specification, which is what the WI suffix in the model number denotes. It is a 4-terminal, single-position ringless socket rated 320 continuous amps at 600V AC, 60 Hz, with lever bypass. Utilities outside Wisconsin publish their own approved-socket lists, so the WI variant is the one to order for a Wisconsin service.
2) Does this Milbank 320A meter socket come with a main breaker?
No. The U1897-X-WI is a meter socket only, with no main breaker and no breaker space. You will need a separate service disconnect downstream, which on a 320A (400A rated) service is typically two 200A panels or a separate main disconnect. There is one meter position and no receptacles.
3) Is this meter socket set up for underground service or overhead?
Underground. Cable entry on the U1897-X-WI is underground, and it ships with a large closing plate covering the hub opening. For an overhead drop you would need a socket configured for a hub and a weatherhead riser instead.
4) What size conductors land in this socket and what are the terminals?
Line and load connections are 3/8 inch studs, so you lug to them with compression or mechanical terminals sized for your 320A service conductors, typically parallel sets on a 400A-class residential service. Equipment grounding is a 3 barrel ground lug.
5) Is a 4-terminal socket right for my service, or do I need 5-jaw?
The U1897-X-WI is 4 terminal, single phase, 600V AC, which covers a standard 120/240V single-phase residential or small commercial service. A 5-jaw socket is used for network or three-wire network metering that requires the extra neutral-sensing jaw, so if your utility specified 5-jaw this is not the socket to order.
6) How big is the Milbank U1897-X-WI socket and how does it mount?
It measures 4.844 x 15 x 30 inches (L x W x H) and is surface mounted to the wall. Lay out at least 30 inches of vertical clear wall and confirm meter center height with the serving utility before you set the anchors.
7) Can the meter be pulled without killing power to the building?
Yes. The lever bypass lets the meter be removed and replaced while the service stays energized, which is what utilities and meter techs want on a 320A single-phase service. The ringless cover design also means no sealing ring to deal with when the cover comes off.
8) Is this meter socket rated for outdoor installation in Wisconsin winters?
It carries a Type 3R rating and is UL Listed, so it is suited to outdoor wall mounting with rain and sleet exposure. The body is G90 galvanized steel with a powder coat finish for corrosion resistance, and internal insulation is glass polyester.
9) What is the Milbank part number for the Wisconsin 320A ringless socket with large closing plate?
Order model U1897-X-WI. It sits in Milbank's 4T32 product family, the 4-terminal 320A group, and the X-WI suffix identifies the Wisconsin area configuration with the large closing plate for underground entry.
