Milbank U1681-RL – Frequently Asked Questions

1) Is the Milbank U1681-RL meter socket the right one for a 3-phase 4-wire service?
The U1681-RL is a 7 terminal socket, which is the jaw count utilities specify for 3 phase, 4 wire service metering. It is rated 3 phase, 600V AC, 60 Hz, at 125 continuous amps, with one meter position. If your utility called for a 5 jaw (3 phase 3 wire) or a 4 jaw single phase socket, this is not the one. Always confirm the jaw configuration against the utility's approved meter list before you set it.
2) What size conductors can I land in this 125 amp Milbank meter socket?
Both line and load terminals take 6 AWG through 2/0 AWG, and they are lay-in type lugs, so you drop the conductor in rather than threading it through a hole. That range covers the usual copper and aluminum feeder sizes for a 125 amp service. Equipment grounding is handled by a ground lug in the enclosure.
3) Can the Milbank U1681-RL be used with an underground service lateral?
No. The U1681-RL is built for overhead cable entry and comes with a small hub opening at the top for the service mast or raceway. For an underground lateral you want a socket configured for bottom feed. Using the overhead-entry version on a lateral means an unused top hub and no proper bottom entry provision.
4) Does this Milbank socket include a main breaker or a meter bypass?
Neither. The U1681-RL is a socket only, with no main breaker and no bypass provision. Overcurrent protection has to come from a separate disconnect or panel downstream, and because there is no bypass, the utility has to pull the meter to de-energize for service work. If your utility requires a lever bypass for maintenance under load, specify a bypass model instead.
5) Can this Milbank meter socket be mounted outdoors on an exterior wall?
Yes. It is UL Listed with a Type 3R enclosure, which is the rainproof rating for outdoor wall-mounted service equipment. The body is G90 galvanized steel with a powder coat finish, and it mounts to the surface of the wall. Type 3R is not rated for washdown or dust-tight locations, so an indoor process area with heavy airborne dust calls for a different enclosure type.
6) What does ringless mean on a Milbank meter socket, and does it change the meter I can use?
Ringless refers to how the cover is secured: instead of a sealing ring clamping the meter to the socket, a hinged or lift-off cover goes over the meter and is sealed by the utility. The meter itself is the same, what matters is the jaw count, which here is 7 terminal. Utilities specify ringless or ring style by territory, so order to whichever your serving utility approves.
7) Will this socket work on a 480Y/277V three phase service?
The insulation and jaw assembly are rated 600 volts AC, which covers 480Y/277V as well as 208Y/120V three phase four wire systems at 60 Hz. The insulating base is glass polyester. Current is the other limit: 125 continuous amperes, so size the service accordingly.
8) I need to order replacement meter sockets to match what is already on my buildings. What identifies this Milbank unit?
Order it as Milbank model U1681-RL, family code MD7T. That designation covers the 7 terminal ringless 3 phase socket, 125 amp, overhead entry with small hub opening, no bypass. If the existing cans on your property are labeled with a different Milbank number, match the jaw count, amperage, entry direction and bypass provision before assuming they interchange.
