Milbank U7021-DL-QG-KK – Frequently Asked Questions

1) Will the Milbank U7021 meter socket accept 4/0 aluminum service entrance cable?
Yes. Both line and load side terminals on the U7021 take 6 AWG through 350 kcmil, so 4/0 sits comfortably in the middle of that range. The terminals are lay-in type, which means you drop the conductor into the jaw rather than fishing it through a closed lug, a real time saver when you are working a 200 amp service overhead on a ladder.
2) Does the Milbank U7021 come with a main breaker, or do I still need a separate panel?
No main breaker. The U7021 is metering only, a single meter position with no breaker and no receptacle, so the service disconnect and distribution have to come from a separate panel or a main breaker enclosure downstream. If you want the meter and the main in one can, you need a meter main combination, not this socket.
3) What is the difference between the 2 inch hub and the small hub open versions of the Milbank U7021?
It comes down to how the service conductors enter the top of the can. The 2 inch hub versions (the DL codes) ship with a closed 2 inch threaded hub for rigid conduit, and there is a 2.5 inch hub version as well. The small hub open versions (the RL codes) come with an open small hub so you fit the raceway or connector the utility calls for. Either way this is an overhead cable entry socket, so the entry is at the top for a service drop or a mast.
4) Can I use the Milbank U7021 ringless socket for an underground service lateral?
Not as configured. The U7021 is built for overhead cable entry, with the hub at the top for a service drop or mast. For an underground lateral you want a socket with bottom feed provision instead. If your utility runs the lateral up a riser into the top hub, the U7021 works, but confirm that detail with the serving utility before you set the can.
5) Which Milbank U7021 do I order for a utility that requires a barrel lock?
Three lock arrangements are offered. The BL versions take a 9/16 inch barrel lock and include the bracket, available with a 2 inch hub and triplex ground or with small hub open in both plain and horn bypass form. The BLG versions carry a 7/8 inch barrel lock provision with horn bypass and triplex ground. There is also an HSP version with a stainless steel hasp if your utility seals with a padlock rather than a barrel lock.
6) Are there Milbank U7021 versions built to a specific utility's approved list?
Yes, four utility specific builds exist alongside the generic ones: City Public Service Board of San Antonio, Duquesne Light Company, Consumers Energy, and Rochester Gas and Electric. If you are working in one of those territories, order the matching version rather than the generic equivalent, because the utility approval is what gets the meter set. Outside those territories the standard triplex ground versions are the ones to look at.
7) Do I need triplex ground or quadplex ground on a 200 amp Milbank U7021 socket?
Triplex ground is the common single phase three wire arrangement and most of the U7021 versions are built that way. Quadplex ground versions are offered with horn bypass, in both 2 inch hub and small hub open form, for services run with a four conductor drop. Match whichever the service conductors coming to the building actually are, because the ground provision is fixed in the can and cannot be changed in the field.
8) What does horn bypass do on a Milbank meter socket, and do I need it?
Horn bypass lets the utility maintain power to the load while the meter is pulled, so the service does not go dark for a meter change or test. Many utilities require it; some do not allow it. Most U7021 versions carry the KK horn bypass suffix, and plain non bypass versions are offered too, such as the small hub open triplex ground build. Check the utility's meter spec sheet, since this is their call rather than the electrician's.
9) Will the Milbank U7021 hold up mounted outdoors on an exterior wall?
It is built for it. The enclosure is G90 galvanized steel with a powder coat finish and carries a Type 3R rating, which covers rain, sleet and ice on an outdoor wall. Mounting is surface mount, so it lands flat on the wall or a backboard rather than recessing into the framing.
10) Is a ringless meter socket the right choice, or should I get a ring type?
Ringless means the cover itself seals over the meter, with no separate locking ring around the meter rim. Utilities that use sealed covers require ringless; utilities that seal at the ring require ring type. It is not an installer preference, it is dictated by the serving utility. The U7021 is ringless throughout, in every hub and ground configuration offered.
11) Can I standardize on one Milbank U7021 part number across a portfolio of buildings?
Only within one utility territory. The U7021 family shares the same 200 amp single phase 4T20 platform, the same enclosure and the same 6 AWG to 350 kcmil terminals across all 17 configurations, so the socket itself is consistent. What changes between properties is the hub size, the ground provision, the lock arrangement and the utility specific approval. Property groups spanning several utilities typically standardize on the U7021 as the base and vary the suffix by territory.
