Milbank U9551-RXL-QG-AMS – Frequently Asked Questions

1) Will the Milbank U9551-RXL meter socket accept 4/0 aluminum service entrance cable?
Yes. Both line and load side lay-in terminals on the U9551-RXL take 6 AWG through 350 kcmil, so 4/0 aluminum SE cable lands with room to spare on either side. Lay-in terminals mean you drop the conductor in rather than threading it through a lug barrel, which speeds up a service change on a ladder.
2) Is this a 4-jaw or 5-jaw meter socket, and does the 5th terminal matter for my utility?
The U9551-RXL is a 5 terminal (5-jaw) single-phase socket. Many utilities require the 5th terminal for a network or neutral-sensing meter on 120/240V residential service, and a 4-jaw socket will not pass that inspection. One variant, U9551-RXL-5T9-IL, places the 5th terminal specifically in the 9 o'clock position with 7/16 inch knockouts and lock provision, which is how some utilities specify it. Check your utility's meter standard for the required terminal position before ordering.
3) Does the Milbank U9551-RXL include a main breaker or disconnect?
No. This is a meter socket only, with no main breaker and no receptacles. The service disconnect and overcurrent protection have to be provided downstream, typically a 200A main breaker panel or a separate service disconnect. If you need metering and the disconnect in one can, you want a meter main combination instead of this socket.
4) Can this meter socket be used for an underground service lateral, or is it overhead only?
Either. Cable entry is rated for overhead or underground, and it ships with the large hub opening adapted to a small closing plate. For an overhead drop you open the hub and install the correct hub for your conduit size; for an underground lateral you leave the closing plate in and bring conduit in through the bottom. The large-hub-to-small-plate arrangement is what gives you both options from one can.
5) What is the difference between the standard U9551-RXL and the QG, TKO, and AMS versions?
All five share the same 200A 5-terminal ringless lever bypass body. U9551-RXL is the base socket. U9551-RXL-QG adds a quadplex ground. U9551-RXL-QG-AMS is the quadplex ground version built to Ameren approval. U9551-RXL-TKO comes with twin knockouts for two conduit runs. U9551-RXL-5T9-IL sets the 5th terminal at 9 o'clock with 7/16 inch knockouts and lock provision. The utility's approved meter list usually dictates which suffix you order.
6) Will this socket work on a 120/240V single-phase residential service?
Yes. It is a single-phase, 1 meter position socket rated 600 VAC maximum at 60 Hz and 200 continuous amps, which covers standard 120/240V single-phase residential and light commercial service. It will not serve a three-phase service, and it meters one position only, so a multi-unit building needs one can per tenant or a ganged multi-position socket.
7) Is the lever bypass on this Milbank socket what my utility means by a bypass socket?
The U9551-RXL carries a lever bypass provision, the type that lets the lineman shunt the line and load jaws with a lever so the meter can be pulled or swapped without dropping power to the building. That is distinct from a horn bypass socket. If the utility meter standard calls for no bypass or specifically for horn bypass, this is not the right can.
8) Is this meter socket rated for outdoor wall mounting in weather?
Yes. It is a UL Listed Type 3R enclosure, which covers rain and sleet on an outdoor wall, built from G90 galvanized steel with a powder coat finish. Mounting is surface mount, so it fastens to the exterior wall face rather than recessing into the stud cavity. For a flush wall installation you need a semi-flush or recessed socket instead.
9) How much wall space do I need for the Milbank U9551-RXL meter can?
The enclosure measures 19 inches in height and 13 inches in width, so plan the wall opening and conduit layout around that footprint plus working clearance to the front per code. On a siding retrofit this is a common swap size for an older 200A can, but confirm your existing conduit stub lines up with the hub or bottom entry before you cut the old one off.
10) Is the Milbank U9551-RXL approved for Ameren service territory?
Ameren Energy is listed among the special features for this family, and the U9551-RXL-QG-AMS variant is specifically the Ameren approved quadplex ground configuration. If the job is in Ameren territory, order the AMS suffix rather than the plain socket so the meter set clears inspection.
11) Does a ringless meter socket need a separate sealing ring?
No. On a ringless socket like the U9551-RXL the cover itself retains the meter, so there is no separate ring to buy or lose. A ring-type socket uses a locking ring over the meter flange and a different cover. The two are not interchangeable, so match the existing style if the utility is reusing their meter and seal hardware.
12) Can I padlock or barrel-lock this meter socket to keep tenants out of it?
The can includes a 7/16 inch knockout for a barrel lock provision, which is the standard utility sealing arrangement for a ringless cover. On a multi-family or commercial property that is how you keep the cover secured between meter reads. The 5T9-IL variant comes with the 7/16 inch knockouts and lock provision called out explicitly.
13) What insulates the jaws in this Milbank meter socket?
Glass polyester carries the jaw assembly in the U9551-RXL. It is the standard thermoset insulating base for a 200A socket, holding dimensional stability and dielectric strength under the heat a fully loaded 200A service puts on the jaws.
