Milbank U5757-O-200 – Frequently Asked Questions

1) Will the Milbank U5757-O-200 meter socket work for a 200 amp overhead service drop?
No. The U5757-O-200 is built for underground service entry and ships with a plain top, meaning there is no hub opening for a weatherhead and conduit riser. For an overhead drop you want the same style of 200A ringless combination socket ordered in an overhead configuration with a hub or hub-closing-plate top.
2) Does this Milbank socket have a meter bypass for hot swapping the meter?
No bypass provision is included. If your utility requires a lever or horn bypass so the meter can be pulled without dropping the load, this unit will not satisfy that requirement and you need a bypass-equipped socket instead.
3) Is the Milbank U5757-O-200 a ringless or ring-type meter socket, and how many jaws?
Ringless, with a 4 terminal (4 jaw) single-position socket, which is the standard arrangement for 120/240V single phase residential service. Utilities generally specify ringless or ring-type, so confirm which your local provider accepts before ordering.
4) Can I use this on a 208Y/120 three phase service?
No. It is a 1-phase device rated up to 240 volts AC at 60 hertz with a 4 terminal socket. A three phase service needs a 7-jaw socket rated for that system.
5) Does this combination socket include the service disconnect, or do I still need a separate main?
The disconnect is built in. One 200 ampere main breaker is factory installed, giving you overcurrent protection and the service disconnecting means in the same can, so the panel downstream can be a main-lug or main-breaker load center as you prefer.
6) Is this Milbank meter socket rated for outdoor mounting on an exterior wall?
Yes. It is UL Listed with a Type 3R enclosure, which is the rain-rated construction utilities expect for an exterior service. The shell is G90 galvanized steel with a powder coat finish, and it surface mounts flat to the wall.
7) What wall space do I need for the Milbank U5757-O-200?
Plan for a footprint of 5.75 x 17.375 x 34 inches. It is the wide-shell style, so check your stud layout and any clearance the utility requires around the meter before you set it.
8) Are there any branch breaker spaces or GFCI receptacles in this Milbank unit?
None. It carries zero receptacles and a single main breaker only, so it is a meter-main, not an all-in-one panel. Branch circuits have to be fed from a separate load center.
9) Is 200A continuous the real rating, or is that a momentary number?
It is a 200 continuous ampere rating, so the socket and busing are rated to carry a full 200 amps continuously, which is what you need for a 200 amp service upgrade rather than a derated unit.
