Milbank U1432-O – Frequently Asked Questions

1) Will the Milbank U1432-O meter socket work for an overhead service drop?
No. The U1432-O is built for underground cable entry and comes with a plain top, meaning there is no hub opening for a service mast or weatherhead conduit. For an overhead drop you need a socket with a hub or a hub closing plate opening at the top. Use this one where the service lateral comes up from below grade.
2) Does this 320 amp Milbank socket include a main breaker or a meter bypass?
Neither. The U1432-O is a straight 320 continuous amp socket only, with no main breaker and no bypass provision. If your utility requires a lever or horn bypass for meter changes under load, or your inspector wants a service disconnect in the same enclosure, this is not the right unit. You will need a separate downstream main disconnect to complete the service.
3) Is a 4-jaw ringless meter socket the right choice for a 120/240V single phase residential service?
Yes, that is exactly the configuration. The U1432-O is a 4 terminal single phase socket rated 600V AC at 60 Hz, which covers standard 120/240V single phase residential and light commercial metering. Ringless means the meter is held by the cover rather than a sealing ring, so check that your serving utility accepts ringless sockets, since some require ring type.
4) What size lugs and terminations does the Milbank U1432-O accept for a 320 amp service?
The line and load connections are 3/8 inch stud terminals, so your conductors land on lugs sized for those studs. Equipment grounding is handled by two barrel ground lugs included in the enclosure. On a 320 continuous amp service you are typically landing parallel or large single aluminum conductors, so confirm your lug kit matches both the stud size and the conductor range before you pull cable.
5) How much wall space do I need to mount a Milbank U1432-O meter socket?
Plan for roughly 13 inches of width and 29.75 inches of height on the wall, with the enclosure projecting 4.875 inches off the surface. It is a surface mount unit, so it fastens to the exterior wall rather than sitting flush. Add clearance above and below for the underground conduit stub and for the utility's required working space around the meter.
6) Can this meter socket be installed outdoors and will it hold up in a coastal or wet climate?
It is a Type 3R enclosure and UL Listed, so it is intended for outdoor wall mounting and rain exposure. The shell is G90 galvanized steel with a powder coat finish for corrosion resistance, and the internal insulation is glass polyester. Type 3R is rain and sleet rated, not watertight, so it should not be used where it will be hosed down or submerged.
7) Can I meter two units or apartments with this Milbank socket?
No. The U1432-O has a single meter position and no receptacles, so it serves one metered service only. For a duplex or multi-unit building you need a multi-position meter stack or one socket per unit. It does suit a single underground-fed dwelling, a small office, or a retail space drawing on one account.
