Milbank U3730-O – Frequently Asked Questions

1) Does the Milbank U3730-O meter socket pedestal come with a main breaker installed?
No. The U3730-O is supplied with main breaker provision only, meaning the space and mounting are there but no breaker is included: the spec lists no main breaker and a main breaker count of zero. You order the breaker separately to suit your service, and the socket itself is rated 200 continuous amps, single phase, up to 240V AC.
2) Will a 4/0 aluminum or 350 kcmil copper service conductor fit the lugs on this 200A Milbank pedestal?
Yes. The line side terminals on the U3730-O take two conductors each, sized 6 AWG through 350 kcmil, so 4/0 aluminum and 350 kcmil both land. They are double mechanical terminals, and the equipment ground is a 4 barrel ground lug.
3) Is this Milbank pedestal meter socket for overhead or underground service?
Underground. Cable entry is underground and the unit is a single pedestal direct bury design, so the conductors come up through the pedestal from a buried lateral. The top is a plain top closing plate, with no hub for an overhead riser, so it is not the unit for an aerial drop.
4) Will a 4-jaw ringless meter fit this socket, and do I need a meter ring?
The U3730-O is a 4 terminal ringless socket, so it accepts the standard 4-jaw single phase meter used on 120/240V services and needs no sealing ring. Jaw count has to match what the utility sets: if your utility supplies a 5-jaw or 7-jaw meter, or requires a ring type socket, this is the wrong unit.
5) Does this Milbank socket have a meter bypass for hot-swapping the meter?
No bypass. The U3730-O is a no-bypass socket, so the meter cannot be pulled under load without interrupting service. Utilities that require a lever or horn bypass for 200A self-contained metering will reject it, so check the utility's approved equipment list before you set the pedestal.
6) How tall is the Milbank U3730-O pedestal and how much room do I need to set it?
Overall size is 15.125 inches long by 9.875 inches wide by 48 inches high. Plan the excavation and the clear working space in front of the meter around that 48 inch height, since the buried portion of the pedestal reduces the exposed height above grade.
7) Can I feed more than one circuit out of this meter pedestal?
It is set up for three branch circuits, with one meter position. There are no receptacles built in, so if you need convenience outlets at the pedestal for an RV site or jobsite power, you need a different unit with integral receptacles.
8) Is this meter socket rated for outdoor direct bury in a wet, corrosive location?
The enclosure is UL Listed and Type 3R, built from G90 galvanized steel with a powder coat finish, which is the standard combination for outdoor rain-exposed service equipment. Insulation is glass polyester. Type 3R protects against rain, sleet and snow; it is not a submersion or washdown rating.
9) What is the exact Milbank part number to order for this pedestal meter socket?
Order Milbank U3730-O. It is the 4 terminal ringless, plain top, single pedestal direct bury socket with one main breaker provision, 200A, 1 phase, 60 Hz, up to 240V AC.
