Milbank U5903-X-KK-K1-PED – Frequently Asked Questions

1) Will a Milbank U5903-X 3-position meter socket work on a 120/240V single-phase apartment service?
Yes. The U5903-X is built for single-phase service rated up to 240 volts AC at 60 Hz, with three metered positions in one enclosure. That is the normal configuration for a triplex or three-unit building on a standard residential/light-commercial single-phase service. It will not serve a three-phase service.
2) Is the 100A rating on the Milbank U5903-X per meter or for the whole socket?
The 100 amp continuous rating on the U5903-X applies to each of the three metered positions, each fed as its own branch circuit off the socket. Three branch circuits, three meter positions. Size the incoming service conductors for the total connected load, not for 100A.
3) Does the Milbank U5903-X come with main breakers, or do I have to buy them separately?
Breakers are not included. The U5903-X is a breaker-provision socket: the branch positions are prepped to accept main breakers, and you order the breakers to match the load you are protecting. Plan for that on the takeoff so the gear is not sitting on the wall waiting for three breakers.
4) What size conductors can I land in a Milbank U5903-X meter socket?
Line side lugs take 6 AWG through 350 kcmil, and the load side lugs take 1 AWG through 300 kcmil. Equipment grounding is a ground lug. That line-side range covers most 100A to 400A service laterals feeding a three-unit socket, so you rarely need reducers or split-bolt transitions at the can.
5) Can a Milbank U5903-X be used for an underground service lateral, or is it overhead only?
Either. The U5903-X accepts overhead or underground cable entry, and it ships with a large hub closing plate so you can fit the hub your utility requires for an overhead drop or close the opening off for an underground feed. Same can either way.
6) Can a Milbank ringless meter socket be mounted outdoors on the side of a building?
Yes. The U5903-X carries a Type 3R enclosure rating and is UL Listed, so it is built for exterior wall mounting where rain and sleet are the exposure. The body is G90 galvanized steel with a powder coat finish, and the internal insulation is glass polyester.
7) What is the difference between the U5903-X and the U5903-X-KK horn bypass version?
The plain U5903-X is the standard socket. The -KK suffix adds horn bypass, which lets the utility pull a meter without dropping power to the tenant. Many utilities require bypass on multi-position sockets, so confirm what your serving utility mandates before you pick between the two. From -KK there are further options: -5T for 5 terminal, -K1 for a single connector, and -PED for pedestal mount.
8) Which Milbank U5903 version do I order for a ComEd or Chicago Housing Authority job?
Order the U5903-X-KK-K1-PED-CECHA. That is the horn bypass, pedestal mount build carrying the CECHA approval, and this family is specifically identified for Commonwealth Edison and Chicago Housing Authority work. Submitting a non-CECHA variant on those jobs is the usual reason a service gets rejected at inspection.
9) I need a barrel lock on the meter socket for utility sealing. Which Milbank U5903 do I specify?
Two barrel lock provisions are offered on the horn bypass body: U5903-X-KK-BL for a 9/16 inch barrel lock, and U5903-X-KK-BLG for a 7/8 inch barrel lock. Ask the utility which barrel size their locks use, because the provision is punched at the factory and cannot be changed in the field.
10) Can I mount a Milbank U5903-X on a pedestal instead of a building wall?
Only if you order the pedestal version. The base U5903-X is a surface mount can. For a free standing installation, specify U5903-X-KK-K1-PED, which is the horn bypass, single connector build configured for pedestal mounting. That is the right call for a manufactured housing site or a lot where there is no suitable wall.
11) What does ringless mean on a Milbank meter socket, and does it change how the meter is installed?
Ringless means there is no separate sealing ring around the meter; the cover itself retains the meter and is sealed by the utility. Utilities generally specify one style or the other and will not accept the wrong one, so confirm your serving utility takes ringless before ordering the U5903-X. Mechanically the socket is the same 100A, 240V single-phase, 3-position unit either way.
12) Does the Milbank U5903-X have room for tenant receptacles or house panel circuits?
No. The U5903-X has zero receptacles and three branch circuit positions, all of them metered. If you need a house meter or an unmetered convenience outlet for common area loads, that is a separate can or a socket configured with a house position.
