Milbank U4031-O-2/200 – Frequently Asked Questions

1) Will a Milbank U4031-O pedestal work for a 400A service, or what is its actual rating?
The Milbank U4031-O ringless lever bypass meter pedestal is rated 320 continuous amperes at up to 240 volts AC, single phase, 60 hertz. That is the standard 320A continuous / 400A intermittent class residential and light commercial service size. It will not serve a true 400A continuous load, and it is single phase only, so it is the wrong unit for a three phase service.
2) What breaker combinations does the Milbank U4031-O dual main pedestal come in?
Four breaker configurations are built on the U4031-O pedestal: one 100A plus one 200A (U4031-O-100/200), two 150A (U4031-O-2/150), two 200A (U4031-O-2/200), and two 200A with the 5th terminal at the 9 o'clock position (U4031-O-2/200-5T9). Every one carries two main breakers behind a single meter position, so you get two independent disconnects, for example a house and a shop or two units, off one 320A service. Pick the 5T9 version only if your utility requires a 5th terminal at 9 o'clock.
3) Does my utility require a 5th terminal on the meter socket, and does Milbank offer that on the U4031-O?
Yes, one version carries it: U4031-O-2/200-5T9 has the 5th terminal at the 9 o'clock position with two 200A mains. Many utilities require a 5th (neutral sensing) terminal at a specified clock position, and the position is not interchangeable. If your utility spec does not call for it, the standard 4 terminal versions (100/200, 2/150, 2/200) are what you want. Check the utility's meter spec sheet for the clock position before you order, because the socket cannot be modified in the field.
4) What size conductors can I land in the Milbank U4031-O meter pedestal?
Line side lugs take 6 AWG through 350 kcmil, and the load side takes 1 AWG through 300 kcmil. For a 320A continuous service that means parallel or large single runs land without adapters on the line side, and the load side accepts up to 300 kcmil per breaker. The equipment ground is a 4 barrel ground lug, and the neutral/load terminations are 3/8 inch studs, so bring lugged conductors or ring terminals for the stud connections.
5) Can the Milbank U4031-O be set directly in the ground, or does it need a concrete pad?
This is a direct bury pedestal, built for underground cable entry with a side wireway, so it is set into the earth with the service laterals coming up inside the enclosure. The body is G90 galvanized steel with a powder coat finish in a Type 3R rated enclosure, which is the outdoor rain and sleet rating. Set the bury depth per the utility's meter height requirement, since the meter face height above finished grade is what the utility inspects.
6) Is the Milbank U4031-O ringless or ring type, and will my utility accept it?
Ringless. The cover overlaps and secures the meter rather than a separate sealing ring clamping it, and the cover is sealed by the utility. Utilities are split on this: some approved lists specify ringless only, others ring type only, and the two are not interchangeable at the meter. Check which style your serving utility requires before you order, because swapping is a whole enclosure change, not a cover change.
7) Does the Milbank U4031-O pedestal include receptacles for a mobile home or RV site?
No receptacles. The U4031-O has zero receptacles and a plain top hub closing plate, so it is a meter main only: one meter position, two main breakers, and underground feeds out. For an RV site or mobile home lot where you need 50A and 30A outlets built into the pedestal, this is the wrong unit, and you want an RV power outlet pedestal instead. Used as a meter main, it feeds a downstream panel or two separate structures.
8) Can I feed two separate buildings from one Milbank U4031-O meter pedestal?
That is what the dual main configuration is for. Two independent main breakers sit behind a single meter position, so one 320A metered service splits into two separately protected feeders, for example a house and a detached shop, or two mobile home lots on one meter. Both loads are billed on the same meter, so if the utility or the tenants need separate billing, you need a multi position meter socket instead. Load side lugs accept 1 AWG through 300 kcmil per feeder.
9) How much room do I need to set a Milbank U4031-O pedestal, and what are its dimensions?
The enclosure measures 5.75 x 25 x 30 inches (5.75 inch depth, 25 inch width, 30 inch height). Plan the trench and the working clearance in front of the meter face accordingly. It is a surface mount unit, so the enclosure body bolts to its support rather than being flush set in a wall.
10) What does lever bypass mean on a meter socket, and do I need it instead of a horn bypass?
Lever bypass puts a manual lever inside the socket that shunts line to load, so the meter can be pulled and swapped without dropping power to the customer. The U4031-O carries that lever bypass provision. Many utilities mandate bypass on 320A class services specifically so a meter change does not mean an outage. If your utility permits a non bypass socket, a plain meter socket is simpler and has fewer moving parts, but you cannot add bypass to it later. Confirm which style your utility's approved meter list names before ordering.
11) Can I add a conduit hub to the top of the Milbank U4031-O for an overhead service drop?
The U4031-O ships with a plain top closing plate and is configured for underground cable entry with a side wireway, which makes it a direct bury unit fed from below. It is not set up as an overhead service entrance socket. For a service drop from a pole, use a meter socket ordered with an overhead hub opening rather than the plain top pedestal.
12) Which Milbank U4031-O breaker option should I pick for a house and a detached garage?
The 1x100A + 1x200A version (U4031-O-100/200) is the usual split when one structure carries most of the load: 200A to the dwelling, 100A to the garage or shop. If both structures need full size services, two 200A mains (U4031-O-2/200) covers it, and two 150A mains (U4031-O-2/150) sits between them for two moderate loads. All four sit on the same 320A continuous, 240V single phase pedestal, so the choice is purely how you want the load divided.
