Milbank U9550-RRL-QG – Frequently Asked Questions

1) Will a Milbank U9550 meter socket work for a 200 amp overhead residential service?
That's exactly what the U9550 is built for. It's a single phase, 5 terminal ringless socket rated 200 continuous amps at 600VAC, 60 Hz, with one meter position and overhead cable entry. The Type 3R enclosure is UL Listed for outdoor mounting. Note there is no main breaker in it, so your disconnect and overcurrent protection have to come from a separate panel or discomnnect downstream.
2) What size conductors can I land in the Milbank U9550 socket?
Both line and load sides take 6 AWG through 350 kcmil, on lay-in terminals so you drop the conductor in rather than fighting a ring lug into a closed hole. That range covers the usual 4/0 aluminum or 2/0 copper 200 amp service conductors with room on either side.
3) What does the 5 terminal jaw count on the U9550 mean, and is that what my utility wants?
Five terminal means four meter jaws plus a fifth neutral/ground terminal, which is the common single phase 3-wire configuration many utilities specify. It is not interchangeable with a 4 terminal socket, and it is not a network or 3-phase 7-jaw socket. Utilities publish an approved meter socket list, so confirm 5 terminal ringless is on yours before you set it.
4) Which Milbank U9550 version do I order for an Ameren service territory job?
Two versions carry the Ameren suffix: U9550-RDL-QG-AMS with a 2 inch hub and quadplex ground, and U9550-RRL-QG-AMS with the large hub opening that adapts down to small hub, also with quadplex ground. Both are the Ameren Energy spec builds. Ordering a non-AMS version in that territory risks the utility refusing the set.
5) What's the difference between the hub, hub opening, and closing plate options on the Milbank U9550?
They change how the service conductors enter the top. U9550-DL comes with a 2 inch hub already on it. U9550-RL has a small hub opening you fit your own hub to. U9550-RRL and the -RRL-QG versions have a large hub opening that adapts down to a small hub opening, so one box covers either hub size. U9550-XL ships with a small closing plate for overhead drops where you don't need a hub at all. Pick based on the raceway or service drop your utility requires.
6) Can I use the Milbank U9550 for an underground service lateral?
No. The U9550 is configured for overhead cable entry, with hub or closing plate options at the top for a service drop. For an underground lateral you need a socket built for bottom feed entry. Using an overhead-configured socket on a lateral will not pass utility inspection.
7) Does the Milbank U9550 include a disconnect or breaker, or do I need a separate panel?
It's a meter socket only: zero main breakers, no breaker provision, and no receptacles. You'll need a separate main breaker panel or service disconnect downstream to meet code. If you want the metering and the disconnect in one enclosure, look at a meter-main combination instead of this socket.
8) Why choose a lever bypass meter socket instead of a plain 200A socket?
The lever bypass lets the utility or an electrician shunt the meter jaws so the meter can be pulled and swapped without dropping power to the load. On a plain socket the customer goes dark while the meter is out. If you're metering a tenant, a medical office, a walk-in cooler, or anything where an outage means a callback, the bypass is the reason to spend the extra money. Many utilities also require bypass on 200 amp residential and light commercial services.
9) What does the QG suffix on a Milbank U9550 meter socket mean?
QG is the quadplex ground option, found on U9550-RRL-QG, U9550-RRL-QG-AMS, and U9550-RDL-QG-AMS. It's a grounding provision some utilities require on their approved socket. If your utility spec sheet calls for a quadplex ground connector, order a QG version rather than adding one in the field.
10) How much wall space do I need for the Milbank U9550 meter socket, and how does it mount?
It's a surface mount enclosure measuring 18.5 inches high by 10 inches wide, so lay out for that footprint plus the working clearance and meter height your utility requires. It fastens to the wall surface rather than recessing into it, so no wall cavity is needed, but you do need backing solid enough to carry the socket and the service conductors.
11) Is the Milbank U9550 socket suitable for coastal or otherwise harsh outdoor exposure?
The enclosure is G90 galvanized steel with a powder coat finish and carries a Type 3R rating, which covers rain, sleet, and outdoor weather on a normal exterior wall. G90 plus powder coat is the standard outdoor build. It is not a stainless or Type 4X enclosure, so for direct salt spray or washdown exposure you want a socket specified for that environment instead.
