Milbank U4029-X-DPL – Frequently Asked Questions

1) Is the Milbank U4029-X-DPL meter socket a 7-jaw 3-phase socket?
Yes. The U4029-X-DPL is a 7-terminal (7-jaw) socket wired for 3-phase service, one meter position, rated 200 continuous amps at 600V AC, 60 Hz. If your utility is calling for a 4-jaw single-phase socket, this is the wrong unit.
2) Will 4/0 aluminum service conductors land in this 200A Milbank socket?
They will. Both line and load terminals take 6 AWG through 350 kcmil, so 4/0 sits comfortably in range on either side. The terminals are lay-in type, which means you drop the conductor in rather than threading it through a closed lug.
3) Does this Milbank socket have a main breaker or disconnect in it?
No. It is a meter socket only, with no main breaker and no receptacles. The service disconnect has to be provided separately downstream, so budget for a separate 200A disconnect or panel to complete the installation.
4) Is the Milbank U4029-X-DPL approved for Delmarva Power territory?
The -DPL suffix marks it as the Delmarva Power and Light configuration, which is why it ships with lever bypass and the large hub closing plate. Utilities publish their own approved socket lists, so if you are working outside Delmarva territory you should be ordering the socket your serving utility spec calls out instead.
5) Can this Milbank socket be installed outdoors on an exterior wall?
Yes, it carries a Type 3R rating for outdoor rain and sleet exposure and is UL Listed. The enclosure is G90 galvanized steel with a powder coat finish, which is the normal build for exterior service equipment in coastal or humid areas.
6) Can the meter be pulled without dropping power to the building?
That is what the lever bypass is for. Throwing the bypass lever carries the load around the meter jaws so the meter can be pulled or swapped while the service stays energized. Only the utility or an authorized party should be operating it.
7) Can this meter socket be fed from an overhead drop, or does it need underground service?
Either works. The socket accepts overhead or underground cable entry, and it ships with a large hub closing plate covering the top hub opening, so you knock out and fit a hub for an overhead riser or leave it plated and come in from below.
8) Does this socket need a separate grounding bond, or is the neutral already bonded?
The neutral is factory bonded to the equipment ground in this socket. On a service-entrance meter installation that is what you want, but if you are installing it downstream of the service disconnect where neutral and ground must stay separated, this bonded-neutral unit is not the correct choice.
9) What does ringless mean on this Milbank meter socket, and does it change how the meter is secured?
Ringless means there is no separate sealing ring clamping the meter to the socket. Instead a hinged or lift-off cover goes over the meter and the utility seals the cover. Utilities specify ringless or ring-type by territory, so match whichever your serving utility requires. The Milbank U4029-X-DPL is the ringless style.
10) Will this handle a 480V 3-phase service?
The voltage rating is 600V AC, so a 480Y/277V or 480V delta 3-phase service is within rating, as is 208Y/120V. Current is the limit to watch: 200 amps continuous, 60 Hz. The 7-jaw configuration is what pairs it to 3-phase 4-wire metering.
