Milbank U3599-O-KK-BLG – Frequently Asked Questions

1) Will the Milbank U3599-O-KK-BLG work for a 200A single-phase residential underground service?
Yes. The U3599-O-KK-BLG is a 200 continuous ampere, single-phase, 5-jaw ringless socket rated 600VAC at 60 Hz, with underground cable entry through a side wireway. That combination is the standard setup for a 200A residential or light commercial underground service drop. One meter position only.
2) Does this Milbank meter socket come with a main breaker or disconnect?
No. The U3599-O-KK-BLG is a socket only, with no main breaker and no receptacles. You will need a separate service disconnect or main breaker panel downstream. It does include a ground lug for the equipment grounding conductor.
3) What size service conductors will the lugs on this 200A Milbank socket accept?
Both line and load terminals take 6 AWG through 350 kcmil, and they are lay-in type, so you drop the conductor in rather than threading it through. That range covers the usual 4/0 aluminum or 2/0 copper 200A service entrance runs with room to spare for parallel-free single conductors.
4) What does the horn bypass on this meter socket actually do for me on a service call?
The horn bypass lets you carry the load around the meter so power stays on while the meter is pulled or swapped. Many utilities require it on 200A sockets for exactly that reason. Check with your serving utility on whether they want bypass or a non-bypass socket before you set it.
5) Can I use this Milbank socket for a 3-phase or 320A service?
No. It is a single-phase, 5-jaw socket rated 200 continuous amps. A 3-phase service needs a 7-jaw socket, and a 320A/400A class service needs a higher-rated socket with heavier lugs. Neither will work with this one.
6) Can I mount this Milbank socket outdoors on the side of a building?
Yes. It is a surface mount enclosure with a Type 3R rating, so it is built for outdoor rain and sleet exposure, and the body is G90 galvanized steel with a powder coat finish for corrosion resistance. It is also UL Listed.
7) Will this socket accept a utility barrel lock, and does it come with the bracket?
Yes. The U3599-O-KK-BLG ships with a 7/8 inch knockout and the angle bracket for a barrel lock provision, so the utility can seal the cover. The barrel lock itself is supplied by the utility.
8) What are the enclosure dimensions of the Milbank U3599-O-KK-BLG so I can lay out the wall space?
The enclosure measures 4.5L x 14W x 15.25H inches. Allow clear working space in front per your local code and enough room below for the underground conduit sweep into the side wireway.
9) Is a ringless socket like this the right choice, or do I need a ring-type meter socket?
That is a utility call, not a preference. A ringless socket uses a lift-off cover that the utility seals, while a ring-type uses a sealing ring around the meter. Most utilities specify one or the other in their service handbook. The U3599-O-KK-BLG is ringless with a barrel lock provision, which is the common combination where the utility seals the cover rather than a ring.
10) I manage a multi-unit property and need individual meters. Can I gang these together?
Each U3599-O-KK-BLG is a single-position socket, so you would be setting one per tenant. For multiple tenants on one service, a multi-position meter stack or a modular metering pack is usually the better buy than a row of individual sockets, since it consolidates the service entrance conductors and the utility seal points.
11) Is the insulating base on this socket suitable for a harsh outdoor environment?
The jaw base is glass polyester, a thermoset insulator that holds up to heat and moisture in outdoor Type 3R service, and it is paired with a G90 galvanized steel powder coated enclosure.
