Milbank U5786-X-K3-K2-5T6-BL-AMS – Frequently Asked Questions

1) Does the Milbank U5786 meter socket include a main breaker, or do I need a separate disconnect?
No main breaker is built in. The U5786 is a meter socket only, with one meter position and no main breaker, so the service disconnect has to be provided separately downstream. Plan the job around a socket plus a separate disconnect or panel, not an all-in-one meter main.
2) What is the difference between the 4 terminal and 5 terminal versions of the Milbank U5786?
Two jaw configurations are offered. The 4 terminal versions (U5786-X-2/K2-BL and U5786-X-K3-K2-BL) are the standard single phase arrangement. The 5 terminal versions (U5786-X-2/K2-5T6-BL-AMS and U5786-X-K3-K2-5T6-BL-AMS) add the fifth jaw and are built to Ameren Energy requirements. Order the one your serving utility specifies, since the meter jaw count is dictated by the utility, not by the load.
3) Will the Milbank U5786 socket take 350 kcmil service conductors, and can I land parallel runs?
Yes. The load side range is two 6 AWG to 350 kcmil per terminal, so dual 350 kcmil parallel runs land directly without adapters. Two of the four configurations use those dual 6 to 350 kcmil double connectors throughout; the other two pair a single 4 AWG to 600 kcmil connector with a double 6 to 350 kcmil connector, which is the one to pick if you are bringing in a single large 600 kcmil conductor on one side.
4) My utility is Ameren. Which version of the Milbank U5786 do I order?
Take one of the two AMS configurations: U5786-X-2/K2-5T6-BL-AMS with dual 6 to 350 kcmil double connectors, or U5786-X-K3-K2-5T6-BL-AMS with a single 4 to 600 kcmil plus a double 6 to 350 kcmil connector. Both are 5 terminal with the barrel lock bracket and are built to Ameren Energy requirements. Choose between them on conductor size.
5) Can a Milbank 320 amp ringless socket be installed outdoors on an exterior wall?
It is built for it. The enclosure is Type 3R and UL Listed, with G90 galvanized steel and a powder coat finish for weather exposure, and it is a surface mount unit that fastens flat to the wall. Type 3R handles rain and sleet on an outdoor riser or building exterior.
6) What does the lever bypass on this Milbank meter socket do for me on a service call?
The lever bypass lets a utility or qualified tech shunt around the meter so the meter can be pulled and changed while the customer stays energized. For a property manager, that means a meter swap does not have to become a scheduled outage for the tenant. All four configurations of the U5786 carry the lever bypass.
7) Does the Milbank U5786 come ready for a utility barrel lock?
Yes. It ships with a 9/16 inch knockout and an angle bracket for a barrel lock provision, which is the standard tamper seal arrangement utilities ask for on a ringless cover. The barrel lock itself is a utility supplied item; the socket provides the prep.
8) Can I use this socket for an underground service lateral, or is it overhead only?
Either. Cable entry is rated for overhead or underground, so the same socket works on a mast riser or a lateral coming up from below. It also includes a large hub closing plate, so if you are not landing a hub for an overhead mast you can close the top opening off.
9) How wide is the Milbank U5786 meter socket for wall layout?
The published dimensions are 17.75 inches width and 6.5 inches length. Use those when laying out the socket beside a disconnect or gutter so you keep the working clearance the inspector will check.
10) Is there a grounding provision in this Milbank socket or do I add a ground bar?
Two barrel ground lugs are provided in the enclosure, so the equipment grounding and grounding electrode conductors land in the socket without adding a separate bar. Insulation on the jaw assembly is glass polyester.
11) Does a ringless meter socket need a separate sealing ring?
No. On a ringless unit like the U5786 the cover itself retains the meter, so there is no separate locking ring to buy or lose. Security comes from the cover plus the barrel lock provision. If your utility mandates a ring type socket, this is not the right unit for that opening.
