Milbank U8878-RL-LR – Frequently Asked Questions

1) Will the Milbank U8878 meter socket work on a 200A single-phase residential service?
Yes. The Milbank U8878 is a 4 terminal ring type socket rated 200 continuous amperes, single phase, 600V AC at 60 Hz, with one meter position. That covers a standard 120/240V single-phase residential or light commercial service at 200A. Note there is no main breaker and no bypass built in, so overcurrent protection has to live elsewhere in the service.
2) Does the U8878 meter socket have a lever bypass or a main breaker?
No to both. The U8878 is a straight meter socket only: no bypass provision and zero main breakers. If your utility requires a horn or lever bypass for hot meter pulls, or if the jurisdiction wants a meter-main combination with the disconnect in the same enclosure, this is the wrong can and you need a bypass or meter-main version instead.
3) What size conductors can I land in the Milbank U8878 meter socket?
Both line and load terminals take 6 AWG through 350 kcmil, and they are lay-in style terminals, so you drop the conductor in rather than threading it through a lug barrel. That range covers typical 200A service conductors in copper or aluminum. Four terminations total.
4) Difference between the U8878-O-LR plain top and the U8878-RL-LR small hub open wide shell?
Two build options on the same 4 terminal 200A socket. The U8878-O-LR has a plain top, so you make your own conduit entry or bring service up from below. The U8878-RL-LR comes with a small hub opening and wide shell, which suits an overhead drop where you need a hub fitting in the top. Electrical guts are identical; pick based on how the service conductors arrive.
5) Can this Milbank meter socket be mounted outdoors on an exterior wall?
Yes. It is surface mount and carries a Type 3R rating, which is the outdoor rating for rain, sleet and ice. The enclosure is G90 galvanized steel with a powder coat finish, and it is UL Listed. Mount it flat to the wall or a meter board; it is not a flush or recessed can.
6) Is the U8878 a ring type or ringless meter socket, and does it ship with the seal ring?
It is a ring type socket, meaning the meter is retained by a sealing ring around the cover rather than a ringless cover that clamps the meter. The U8878 configurations are less seal ring, so the ring itself is a separate item, typically supplied by the serving utility. Confirm your utility accepts ring type before ordering, since many specify one style or the other.
7) Why is it a 4 terminal socket and what service does that match?
Four jaws is the standard arrangement for a single-phase 3-wire 120/240V service: two line jaws and two load jaws, with the neutral bonded separately. A 5 jaw socket is used for network or three-phase applications, so if your utility spec calls for 5 or 7 jaws, this 4 terminal unit will not satisfy it.
8) What is the insulating material behind the meter jaws on this Milbank socket?
Glass polyester. That is the molded insulating base the jaws are mounted to, chosen for dielectric strength and heat resistance in an outdoor 600V, 200A socket.
9) Does this socket include any receptacles for a generator or accessory?
No. The U8878 has zero receptacles. It is a bare metering can with one meter position and four terminals, nothing else. Generator interlock or transfer needs a separate device.
10) What UNSPSC code should I use for the Milbank U8878 on a purchase order?
UNSPSC 39121102 covers this meter socket, and the Milbank family code is 4T20. Those two plus the MPN (U8878-O-LR or U8878-RL-LR) are what procurement systems usually want.
