Milbank UAP7040-RL-TG-KK-BLG-AEP – Frequently Asked Questions

1) Do I still need a separate main breaker or disconnect with the Milbank UAP7040?
Yes. This is a meter socket only, with zero main breakers and no receptacles built in, so it does not provide service disconnect or overcurrent protection. You will pair it with a separate main breaker panel or a meter socket rated disconnect downstream. If you would rather have the disconnect in the same can, you want a meter main combination instead of this socket.
2) What conductor sizes will fit the lugs on this 200A Milbank ringless socket?
Both line and load terminals take 6 AWG through 350 kcmil, so a typical 200 amp service run of 4/0 aluminum or 2/0 copper lands without adapters, and you still have room if the service was sized up to 250 or 350 kcmil. They are lay-in terminals, which means you drop the conductor in and torque rather than fishing it through a closed barrel.
3) Do I need a 5-jaw socket instead of this 4-terminal one?
Depends on the utility and the service. A 4-terminal socket like the UAP7040 is the standard single-phase, 3-wire (120/240V) arrangement. A 5-jaw can is what utilities specify for network or 120/208V single-phase services where a separate neutral-sensing jaw is required. If your utility spec sheet calls for 5 jaws, this one will not be accepted. Confirm the jaw count on the utility's approved-meter-socket list before ordering.
4) Which UAP7040 version do I order if my utility is American Electric Power?
Two of the six configurations carry the AEP approval: the small hub open with horn bypass (UAP7040-RL-TG-KK-AEP), and the same socket with the 7/8 inch barrel lock provision added (UAP7040-RL-TG-KK-BLG-AEP). If AEP is the serving utility, order one of those two rather than a hasp version, and pick the barrel lock model if AEP is locking the can with a barrel lock instead of a wire seal.
5) What is the difference between plain top, small hub open, and small closing plate on the Milbank UAP7040?
It is how the service conductors enter the top of the can. Plain top (UAP7040-O-TG-HSP) has no top opening, for underground or side/back entry. Small hub open (the -RL- models) has a hub opening ready for a service entrance hub or conduit fitting for overhead mast entry. Small closing plate (UAP7040-XL-TG-HSP) ships with the opening covered by a plate, so you can open it later or leave it sealed. The hub itself is a separate part on the open-hub versions.
6) Can this Milbank ringless meter socket be mounted outdoors on an exterior wall?
Yes. The enclosure is UL Listed and Type 3R rated, which is rain and sleet tight for outdoor use, and it is a surface mount can, so it bolts flat to a wall, meter pole, or structure rather than recessing into it. The painted aluminum body is what handles the weather exposure. The can measures 11 inches wide, worth checking against your available wall space between the mast and any adjacent equipment.
7) Is a ringless meter socket the same as a ring-type socket, and can I swap one for the other?
They are not interchangeable covers. A ringless socket like the UAP7040 uses a full lift-off cover that the utility seals, with no separate sealing ring around the meter. A ring-type can has a smaller cover and a locking ring that clamps the meter. Utilities standardize on one or the other, so if the existing can on the building is ring-type and the utility spec calls for ring-type, a ringless replacement will not pass their inspection. The meter itself is the same.
8) Can I meter two apartments off one UAP7040?
No. The UAP7040 is a single meter position, so it serves one metered account. For a duplex or small multi-family building where each unit is billed separately, you need a multi-position socket or a meter stack with one position per tenant, plus whatever jaw count and bypass your utility specifies.
9) Does the barrel lock version of this Milbank meter socket come with the lock?
No, the -BLG- model (UAP7040-RL-TG-KK-BLG-AEP) includes the provision only: a 7/8 inch knockout and an angle bracket for a barrel lock. The barrel lock itself is normally supplied and installed by the serving utility, so you are buying the can prepped to accept theirs.
10) What does triplex ground mean on this Milbank socket and does it affect how I bond the can?
Triplex ground refers to the grounding provision built into the socket for the equipment ground and neutral connection on a single-phase service. It means the can comes with the ground provision in place rather than requiring a field-added ground kit. You still bond and ground per your utility's service rules and the AHJ, and the socket is the 4-terminal, 1-phase arrangement that this grounding scheme is built around.
