Milbank U3786-O-BLG – Frequently Asked Questions

1) Will a 7-jaw meter socket work for my 3-phase 4-wire service?
The Milbank U3786-O-BLG is a 7 terminal jaw, 3 phase socket rated 600V AC at 60 Hz, which is the standard jaw count for 3-phase 4-wire self-contained metering. It has one meter position. A 3-wire single phase service uses a 4-jaw socket instead, so confirm with the utility which configuration they require before ordering.
2) Does this Milbank 200A meter socket include a main breaker or disconnect?
No. The U3786-O-BLG is a meter socket only, with no main breaker and no receptacles. If your installation needs service disconnect ahead of or behind the meter, you order a separate disconnect or a meter/main combination unit. What it does carry is a lever bypass, so the meter can be pulled and replaced without dropping the service.
3) What size conductors can I land in this 200 amp Milbank socket?
Line and load side both take 6 AWG through 350 kcmil, on lay-in terminals, so 4/0 copper or 350 kcmil aluminum for a 200A service both land without adapters. Equipment grounding is handled by 2 barrel ground lugs. Lay-in terminals mean you drop the conductor in rather than threading it through a hole, which is easier in a tight wireway.
4) Is this meter socket set up for underground service or overhead?
Underground. Cable entry is underground with a side wireway, and the top is a plain top hub closing plate, meaning there is no factory hub for overhead conduit mast entry. For an overhead drop you would want a socket ordered with a hub opening instead.
5) Can this Milbank socket be mounted outdoors on an exterior wall?
Yes. It is UL Listed with a Type 3R enclosure, which is the rain, sleet and ice rating utilities normally require for an outdoor service point. Construction is G90 galvanized steel with a powder coat finish, and it is surface mount, so it fastens flat to a wall or a meter pedestal backboard.
6) What are the dimensions of the Milbank U3786-O-BLG meter socket enclosure?
It measures 6 inches deep by 18 inches wide by 19.25 inches high. That footprint matters when you are fitting it between a downspout and a corner, or lining up a bank of sockets on a multi-tenant wall, and the 6 inch depth keeps the projection off the wall modest for a 350 kcmil-capable wireway.
7) Does this socket accept a utility barrel lock?
Yes. The U3786-O-BLG comes with a 7/8 inch knockout and an angle bracket for a barrel lock provision, which is what most utilities specify to seal the cover against unauthorized meter access. The barrel lock itself is a utility-supplied item and is not part of the socket.
8) What does ringless mean on a meter socket, and can I use it where a ring type was installed before?
Ringless means the cover slides over the socket and is secured to the enclosure rather than being clamped on with a sealing ring around the meter. The Milbank U3786-O-BLG is a ringless design. Utilities specify one or the other, and they are not interchangeable covers, so if the existing unit is ring type you need utility approval before swapping to ringless.
9) Why does the lever bypass matter for a tenant building I manage?
With a lever bypass, the utility or an electrician can shunt current around the meter to pull or change it without killing power to the tenant behind it. On a commercial or multi-tenant service where an outage means lost business, that is the difference between a five minute meter swap and a scheduled shutdown. The Milbank U3786-O-BLG has lever bypass built in.
10) What part number do I order for the Milbank 200A 3-phase ringless socket with bypass?
Order Milbank U3786-O-BLG. It falls in Milbank's MD7T product family, which is the 7-jaw 3-phase group, and the UNSPSC code for procurement systems is 39121102.
