Milbank U4702-X-5T9-K3-K2-IL – Frequently Asked Questions

1) Will a Milbank U4702-X meter socket handle a 320 amp residential service?
That is exactly what the U4702-X is built for. It is rated 320 continuous amperes, single phase, 60 Hz, at 600 volts AC, with one meter position. Note there is no main breaker in this enclosure, so overcurrent protection has to live downstream in the panel or a separate disconnect. On a 320A (400A class) service that usually means two 200A panels or a 400A disconnect fed from the load side.
2) Do I need the 4 terminal or the 5 terminal version of the Milbank U4702-X?
Your utility decides that. Four terminal is the standard single phase socket and covers most residential and light commercial overhead or underground services. Five terminal adds a fifth jaw at the 9 o'clock position, which some utilities require for network metering or for a particular meter form. The five terminal build is ordered as U4702-X-5T9-K3-K2-IL. Call the serving utility before you order, because a socket with the wrong jaw count will not pass their meter set.
3) What size conductors can I land in a Milbank 320A ringless meter socket?
Line side takes 4 AWG through 600 kcmil on a single connector, or two conductors of 1/0 AWG through 250 kcmil if you are paralleling. Load side is a double connector taking two conductors of 6 AWG through 350 kcmil, which is what lets you feed two panels out of one socket on a 320A service. Landing 350 kcmil aluminum or 4/0 copper per leg on the load side is well within range.
4) Can a Milbank U4702-X ringless meter socket be mounted outdoors on an exterior wall?
Yes. It is a UL Listed Type 3R enclosure, so it is rated for outdoor use against rain, sleet and ice. The body is G90 galvanized steel with a powder coat finish, and it surface mounts to the wall. Type 3R is not rated for washdown or dust tight service, so an indoor mechanical room or a hosed down area calls for a different enclosure type.
5) What does the IL suffix mean on Milbank U4702-X part numbers?
IL is the barrel lock provision, a 7/16 inch knockout that lets the utility fit a barrel lock through the cover. Order U4702-X-IL for the four terminal socket with that provision; the plain U4702-X comes without it. Utilities that lock their sockets rather than seal them will reject a socket with no lock provision, so ask before you pick between the two.
6) Can I feed two 200 amp panels from one Milbank 320A meter socket?
Yes, and that is the usual reason to buy a 320A class socket. The load side is a double connector rated for two conductors of 6 AWG through 350 kcmil, so you land one set to each panel out of the same socket. There is no main breaker in the socket, so each panel needs its own main, and you are limited to six disconnects under standard service rules.
7) What does lever bypass do on a meter socket, and do I need it?
Lever bypass lets the meter be pulled and replaced while the service stays energized and the load stays on. Throw the lever and current routes around the meter jaws instead of through them. Many utilities require bypass on 320A class services, and property managers with tenants who cannot take an outage generally want it. If your utility does not require bypass and nobody is going to be swapping meters hot, a non-bypass socket is the simpler order.
8) Is the Milbank U4702-X ringless or does it take a sealing ring?
Ringless. The cover itself seals the meter in place rather than a separate ring clamping around it, and the utility applies its seal to the cover. Ringless is the more common requirement in North America, but it is utility specific, so confirm which style your serving utility accepts. A ring type socket and a ringless socket are not interchangeable once the meter is set.
9) Can I bring service into the Milbank U4702-X from underground, or is it overhead only?
Either one. The U4702-X accepts overhead or underground cable entry, and it ships with a large closing plate on the hub opening so you can fit the hub or fitting your entry method calls for. For overhead you cut in a service entrance hub at the top; for underground you run conduit into the bottom and leave the top plate closed.
10) What do the K3 and K2 suffixes add to a Milbank U4702-X socket?
They call out the connector build: K3 is the single line side connector taking 4 to 600 kcmil, K2 is the double load side connector taking 6 to 350 kcmil. U4702-X-K3-K2-IL is the four terminal socket with both of those plus the 7/16 inch lock knockout. If you are feeding two panels off the socket, the double load side connector is the one that matters.
11) Does the Milbank U4702-X have a place to land the grounding electrode conductor?
There is a ground lug in the enclosure for the equipment ground. Internal insulation is glass polyester. Whether the neutral is bonded at the socket or downstream is a service configuration and code question for your AHJ, but the lug is there to terminate to.
