Milbank U4581-RL – Frequently Asked Questions

1) Will the Milbank U4581-RL meter socket work on a 200A single-phase residential service?
Yes. The U4581-RL is rated 200 continuous amperes, single phase, 600V AC at 60 Hz, with one meter position and a 5-terminal (5 jaw) socket. The 5-jaw configuration is what utilities specify for single-phase three-wire service with a neutral landing. Line and load lugs each take 6 AWG through 350 kcmil, which covers typical 200A copper or aluminum service entrance conductors.
2) Does this Milbank socket have a main breaker or disconnect in it?
No. The U4581-RL is a meter socket only, with no main breaker and no receptacles. Overcurrent protection has to come from a separate main breaker panel or service disconnect downstream. The lever bypass is not a service disconnect either, it only lets the meter be pulled without dropping power to the load.
3) Can I mount this Milbank socket outdoors, and how big is the enclosure?
Type 3R rated and UL Listed, so it is built for outdoor wall mounting with protection from rain and ice. The enclosure is G90 galvanized steel with a powder coat finish and surface mounts flat to the wall. Overall size is 4.844 x 13 x 19 inches, so allow a wall area taller than 19 inches plus working clearance in front per code.
4) Is this a ringless meter socket or a ring-type, and does it matter which my utility accepts?
It is ringless. A ringless socket uses a one-piece cover that slides over the hub flange and is sealed at the bottom, rather than a separate sealing ring clamping the glass. Utilities specify one style or the other and the covers are not interchangeable, so a ringless socket will not accept a ring-type cover. Check which your serving utility requires for the territory before you set it.
5) Can I feed this socket from an overhead drop, or does it only take underground service?
Both. The U4581-RL accepts overhead or underground cable entry. It ships with a small hub opening closing plate at the top, so for an overhead mast you remove the plate and install the hub sized to your conduit. For underground lateral, leave the top plate in place and bring the conductors in from the bottom. The hub itself is a separate item, not part of the socket.
6) Will 4/0 aluminum service entrance cable land in this Milbank socket's lugs?
Yes. Both line and load terminals accept 6 AWG through 350 kcmil, and 4/0 aluminum sits well inside that window, as does 2/0 copper. The terminals are lay-in type, so you drop the conductor into the lug and torque it down rather than threading it through a closed barrel, which makes a service change on a tight raceway considerably easier.
7) Can I use this meter socket on a 3-phase service?
No. The U4581-RL is a single-phase, 5-terminal socket. Three-phase metering needs a 7-jaw socket, and dropping a 3-phase service into a 5-jaw can will not meter correctly. For 120/240V single-phase three-wire residential and light commercial service at 200A, it is the right can.
8) What does the lever bypass on a meter socket actually do for me on a service change?
The lever bypass shorts line to load inside the socket so the meter can be removed or swapped without interrupting power to the building. On an occupied building, a tenant-sensitive install, or a meter exchange, that is the difference between a routine swap and an outage. Many utilities require a bypass socket on 200A services for exactly that reason, so confirm your utility's accepted socket list before ordering.
9) What is the difference between the Milbank U4581-RL and the U4581-RL-QG?
Two versions are built on the same 200A 5-terminal ringless lever bypass body. The standard U4581-RL is the plain socket. The U4581-RL-QG adds a quadplex ground, which gives you the grounding provision for a quadplex service conductor termination rather than having to add one separately. Electrically the ratings are the same; pick the QG when your utility or inspector wants the factory ground provision.
10) How durable is the Milbank meter socket enclosure for a coastal or high-humidity site?
The can is G90 galvanized steel with a powder coat finish over it, which is the standard two-layer approach for outdoor service equipment, and the socket block uses glass polyester insulation rather than a phenolic. Combined with the Type 3R rating it is intended for permanent exterior exposure. In heavy salt air, plan on the usual inspection of the hub seal and cover gasket as part of normal MRO rounds.
