Milbank U9700-RRL-BLG – Frequently Asked Questions

1) Will a Milbank U9700-RRL 7 terminal socket work for a 3-phase 4-wire service, or is it a single-phase can?
Seven jaws is the 3-phase configuration. The U9700-RRL is a 3 phase, 60 Hz meter socket rated 200 continuous amps at 600 volts AC, with a single meter position. A single-phase residential service uses a 4 or 5 jaw socket, so if the utility is setting a 1-phase meter this is the wrong can. Confirm the jaw count on the utility's meter form before ordering.
2) Is the Milbank U9700-RRL socket for overhead or underground service?
Overhead. The U9700-RRL is built for overhead cable entry, with a large hub opening adapted down to a small hub opening on top for the service mast or raceway. An underground lateral feeding a socket from below needs a bottom-fed can instead, so this is not the part for a pad-mount or URD service.
3) Does the Milbank U9700-RRL have a main breaker or disconnect in it?
No. It is a meter socket only, zero main breakers and no receptacles, so the service disconnect has to come from a separate panel or fused disconnect downstream. If the job calls for meter and main in one enclosure, you want a meter-main combination, not this socket.
4) Which Milbank U9700-RRL version do I order if the utility requires a barrel lock or a sealing hasp?
Six versions of the U9700-RRL are built for exactly that decision. Standard is U9700-RRL. For a barrel lock provision there are two sizes: U9700-RRL-BLG for a 7/8 inch barrel lock, and U9700-RRL-QG-BL for a 9/16 inch barrel lock. A stainless steel hasp version is U9700-RRL-QG-HSP. Quadplex ground versions are U9700-RRL-QG, and U9700-RRL-QG-AMS for the Ameren approved build. The utility dictates which locking provision they will accept, so match their spec sheet to the suffix.
5) Is the Milbank U9700-RRL approved for Ameren territory?
Ameren is called out on this socket, and there is a dedicated Ameren approved build, the U9700-RRL-QG-AMS with quadplex ground. If the service is in Ameren territory, order that suffix rather than the standard version, since the utility's approved list is what the meter tech works from at the set.
6) Can the Milbank U9700-RRL ringless meter socket be installed outdoors on an exterior wall?
Yes, it is UL Listed and Type 3R rated, which is the rain-tight outdoor rating for a surface mounted enclosure. The body is G90 galvanized steel with a powder coat finish for corrosion resistance, and the jaw assembly is insulated with glass polyester. Type 3R is not submersible or hosedown rated, so a washdown or below-grade location needs a higher enclosure type.
7) How much wall space do I need for the Milbank U9700-RRL meter socket?
The can is 18.5 inches high and 10 inches wide, surface mounted. Lay that out with the meter center landing in the utility's required height window, and leave room above for the hub and mast, since the service entrance comes in from overhead.
8) What is the difference between a ringless meter socket and a ring-type socket, and which one does my utility want?
A ringless socket like the U9700-RRL uses a hinged or lift-off cover sealed by the utility instead of a separate locking ring clamping the meter to the socket rim. The utility specifies one or the other in its service handbook, and they are not interchangeable at the meter set. Ringless is the common requirement across much of the Midwest, including Ameren territory, which this socket is built for. Get the utility's answer before ordering, because a ring-type can on a ringless spec gets rejected.
9) What does the large to small hub adapter on the Milbank U9700-RRL mean for my conduit?
The socket ships with a hub closing plate that adapts the large hub opening down to a small hub opening, so a smaller service raceway can land on a can punched for the bigger opening. The actual hub or fitting sized to your conduit is a separate item, and the entry is from overhead, so size it to the mast or raceway feeding the can.
10) Is a 200 amp 3-phase Milbank socket enough for a 200 amp service, or do I need to derate?
200 amps here is a continuous ampere rating, not a short-time or intermittent number, so it carries a 200 amp service at 600 volts AC or less without derating the socket itself. Your conductors still get sized by the load calculation and the terminals cap at 350 kcmil, which is the practical ceiling on what you can land.
