Milbank U1284-XL-KK-BLG – Frequently Asked Questions

1) Will a 5-jaw Milbank U128 meter socket work for standard 120/240V single-phase residential service?
The Milbank U128 ringless socket is a 5-terminal, single-phase unit rated 300 volts AC at 60 Hz, 100 continuous amps. The fifth jaw is the neutral/instrument jaw some utilities require, so it is not a drop-in for a utility that specs a 4-jaw socket. Check the utility's approved socket list for your area, since jaw count is dictated by the serving utility rather than by the service itself.
2) Does this Milbank socket include a main breaker or disconnect?
No. The U128 is a meter socket only, with no main breaker and no receptacles. Overcurrent protection has to come from the panel or a separate service disconnect downstream. If you need metering and the main in one enclosure, you want a meter main combination instead.
3) Can this meter socket be used for an underground service lateral, or only overhead?
Both. Cable entry is rated for overhead or underground, so the same socket serves a service drop or a lateral. It ships with a small closing plate on the hub opening, so for an overhead feed you add the hub that matches your conduit size and the utility's requirement. Mounting is surface mount against the wall.
4) What does the horn bypass on this meter socket actually do for me on a service call?
The horn bypass lets you keep the load energized while the meter is pulled, so a meter swap or socket maintenance does not drop power to the tenant. That is why utilities and property managers spec bypass sockets on occupied buildings. Note that it is a bypass, not a disconnect, so it does not satisfy a service disconnecting means.
5) Is the Milbank U128 meter socket rated for outdoor mounting on an exterior wall?
Yes, it is a Type 3R enclosure and UL Listed, which is the standard rating for rain-exposed exterior meter mounting. The can is G90 galvanized steel with a powder coat finish, and the internal insulating base is glass polyester. Type 3R is not washdown or dust-tight, so for a hose-down or heavy-dust environment you need a higher enclosure type.
6) Does the barrel lock provision come ready to lock, or do I need to add parts?
The socket comes with the 7/8 inch knockout and the angle bracket for a barrel lock, which is what utilities and institutional owners ask for on tamper-prone installs. The barrel lock itself is a separate item, usually supplied by the serving utility. Being ringless, the cover is secured by the utility's seal or lock rather than a sealing ring.
7) Is this socket the right choice for 3-phase or 277/480V service?
No. It is a single-phase unit rated to 300 volts AC, so it is limited to 120/240V class single-phase metering. Three-phase or 480V service needs a 7-jaw or 8-jaw socket with the matching voltage rating, not this 5-terminal single-phase can.
8) How much wall space do I need for this Milbank ringless socket?
Published dimensions are 14 inches height and 4.5 inches length, surface mounted. Allow working clearance in front of the meter and enough room above or below for the conduit entry you choose, since the hub opening ships with a closing plate installed.
