Milbank UAP4342-R-K7-K6-BLG – Frequently Asked Questions

1) Do I order the 5 terminal or the 7 terminal Milbank UAP4342 meter socket?
That depends on the service your utility meters. The 7 terminal versions are the UAP4342-R-K7-K6 and the UAP4342-R-K7-K6-BLG; the 5 terminal version is the UAP4362-R-K3-K2, with a barrel lock variant ordered as UAP4362-R-K3-K2-BLG. All are single position, ringless, lever bypass sockets rated 320 continuous amps at 600 VAC, 60 Hz. Your serving utility dictates terminal count, so match their meter requirement before you pick the catalog number.
2) Will 500 kcmil aluminum service conductors land in this Milbank 320A meter socket?
Yes. The line side terminals take a single conductor from 4 AWG up to 600 kcmil, or two conductors each 1/0 AWG to 250 kcmil if you are paralleling. Load side is 6 AWG to 350 kcmil. Terminals are single mechanical type, so no crimping or lugs to buy separately.
3) Can this Milbank socket be mounted outdoors on an exterior wall?
It is built for it. The enclosure is UL Listed and Type 3R rated for outdoor use, aluminum with a powder coat finish for corrosion resistance, and uses glass polyester insulation internally. Type 3R gives you rain and ice protection, not washdown or dust tight service.
4) What does the lever bypass on a 320 amp meter socket actually do for me?
The lever bypass lets a utility or qualified tech pull and replace the meter without dropping power to the load, which matters on a 320 amp service feeding tenants or critical equipment. Many utilities require bypass on services at this amperage, so confirm their spec sheet calls for lever bypass rather than horn bypass before ordering.
5) Is this Milbank socket set up for overhead or underground service entrance?
Both. The large hub opening accepts a hub for overhead mast entry or can be used with underground lateral entry, so the same enclosure covers either job. The hub itself is sized to your conduit and ordered separately.
6) Which Milbank part number comes with the barrel lock provision?
Order the -BLG suffix. UAP4342-R-K7-K6-BLG is the 7 terminal version with a 7/8 inch barrel lock knockout and angle bracket, and UAP4362-R-K3-K2-BLG carries the same 7/8 inch barrel lock provision. The plain UAP4342-R-K7-K6 and UAP4362-R-K3-K2 do not include it.
7) Ringless versus ring type meter socket, which one does my utility want?
This is a ringless socket, meaning the cover itself is sealed by the utility rather than held by a separate sealing ring. Utilities specify one or the other and will reject the wrong style at inspection, so check their approved meter equipment list. If they require a ring type, a ringless enclosure is not a substitute.
8) Is a 320 amp meter socket the right choice for a 400 amp service?
320 continuous amperes is the standard rating used for what the trade calls a 400 amp residential or light commercial service, since it is rated 320A continuous at 600 VAC, 60 Hz. For a true 400 amp continuous service you need equipment rated accordingly. Confirm the utility is calling for 320/400 class metering.
