Milbank U4252-RXL-K2 – Frequently Asked Questions

1) Will the Milbank U4252-RXL-K2 meter socket work on a 200A single-phase 120/240V residential service?
Yes. The U4252-RXL-K2 is rated 200 continuous amperes, single phase, 60 Hz, with a voltage rating of 300 volts AC, which covers a standard 120/240V single-phase residential or light commercial service. It has one meter position and a 4-terminal jaw configuration, which is the usual arrangement for a 3-wire single-phase service.
2) Does this Milbank ringless socket include a main breaker or bypass?
No. The U4252-RXL-K2 is a meter socket only, with no main breaker and no bypass provision. If the utility or the job requires a lever or horn bypass for hot meter pulls, or you need an all-in-one meter-main, this is not the right unit. Overcurrent protection has to come from a separate panel or disconnect downstream.
3) What size conductors can I land in this 200A Milbank meter socket?
Line side takes two conductors per terminal, 6 AWG through 350 kcmil, using double mechanical terminals. Load side accepts 6 AWG through 350 kcmil. That range covers typical 200A copper or aluminum service entrance cable, and the two-conductor line side terminals let you land a feed-through or tap without adding a splice can. There is also a ground lug for the equipment grounding conductor.
4) Can this meter socket be used for an underground service lateral, or is it overhead only?
Both. Cable entry is overhead or underground with a center wireway, so the same enclosure works for a service drop through the hub on top or for a lateral coming up from below. The hub opening is a large hub adapted to a small closing plate, so you can close it off or fit the conduit entry the utility requires.
5) Is the Milbank U4252-RXL-K2 rated for outdoor mounting on an exterior wall?
Yes. It carries a Type 3R rating and is UL Listed, so it is built for outdoor wall mounting with protection against rain, sleet and ice. The enclosure is G90 galvanized steel with a powder coat finish, and it is surface mount, so it fastens flat to the wall rather than recessing into it.
6) Can I use this 4-terminal socket for a 3-phase or 5-jaw network service?
No. The U4252-RXL-K2 is a 4-jaw, single-phase socket. A 3-phase 4-wire service or a network meter needs a 5-jaw or 7-jaw socket, so you would need a different unit for those. For a standard single-phase 3-wire 120/240V service, 4 jaws is correct.
7) How much wall space do I need for this Milbank meter socket?
Plan for an enclosure measuring 5.125 x 26.5 x 14 inches overall, with height listed at 14 inches, width at 26.5 inches and depth at 5.125 inches. Allow working clearance in front per your local code and leave room below or above for the wireway entry you are using.
8) What does ringless mean on a Milbank meter socket, and will my utility accept it?
Ringless means the meter is secured by a sealing cover over the socket rather than by a locking ring around the meter rim. Utilities specify one style or the other, and they are not interchangeable in the field, so confirm with the serving utility that ringless is accepted before ordering. The U4252-RXL-K2 is the ringless 4-terminal version in Milbank's G200 family.
9) What part number should I give the inspector or utility for this Milbank socket?
Specify Milbank U4252-RXL-K2. It is the 200A, single-phase, 4-terminal ringless socket with the large hub opening adapted to a small closing plate, one meter position, no bypass and no main breaker. The UNSPSC code for procurement systems is 39121102.
10) What insulates the jaws in this Milbank meter socket?
The jaw assembly is mounted on glass polyester insulation, which holds up to heat and tracking better than plain thermoplastic in an outdoor enclosure. Combined with the double mechanical terminals, that is what carries the 200A continuous rating.
