Milbank U4163-XT-11-LI – Frequently Asked Questions

1) Will a Milbank U4163-XT-11-LI meter socket be accepted on a LIPA/LISCO service on Long Island?
It's built to the Long Island Lighting Company requirement and is LISCO approved, which is why the model carries the LI suffix. That's the reason to pick this one over a generic 800A ringless socket: utilities on Long Island hold their own approved-equipment list, and a socket that isn't on it gets rejected at inspection even when the electrical ratings match.
2) Does the Milbank U4163-XT-11-LI 800A meter socket include a main breaker or a disconnect?
No breaker in it. The 800A socket is metering only, with zero main breakers and no main breaker provision, so overcurrent protection and the service disconnect have to come from separate gear downstream. It also has no bypass provision, meaning the meter can't be pulled under load through an integral bypass, and no receptacles.
3) What wire size can I land in an 800 amp Milbank ringless meter socket?
Line and load terminals both take 6 AWG through 350 kcmil, on double mechanical lugs. Two conductors per phase is how you get to 800 amps here, since a single 350 kcmil won't carry it. Plan your parallel sets and your bending room around 350 kcmil max per lug, and if the design calls for 500 kcmil conductors this socket will not accept them.
4) Is a 13 terminal meter socket right for a 3-phase 4-wire 277/480V service?
13 jaw is the transformer-rated 3-phase configuration, and this one is rated 600 volts AC at 60 Hertz, 3 phase, single meter position. It works with a 277/480V or 120/208V wye service inside that 600V ceiling. If your meter is a self-contained 3-phase form, you want a 7 jaw socket instead, not a 13 terminal.
5) Can this Milbank 800A meter socket be mounted outdoors, and does it handle overhead or underground feed?
Type 3R and UL Listed, so it's rated for outdoor use against rain, sleet, and ice. Cable entry is set up for either overhead or underground, and it ships with twin large hub closing plates so you cut and hub only the entry you actually use and leave the other plate closed. The enclosure is G90 galvanized steel with a powder coat finish.
6) How much wall space do I need for the Milbank U4163-XT-11-LI meter socket?
Lay out for 10 x 26 x 51 inches, with 51 inches the height and 26 inches the width. It's a surface mount unit, so the full 51 inch dimension sits on the wall and the roughly 10 inch depth projects out. On a crowded meter bank or a narrow pilaster, check the 26 inch width against adjacent gear before the wall goes up.
7) What does the test switch on the U4163-XT-11-LI do for a metering tech?
The test switch lets a utility or test technician shunt the CT secondaries and open the potential circuits to verify or swap the meter without breaking the primary service connections. On a transformer-rated 13 terminal installation that matters, because there's no bypass provision in this socket, so the test switch is the safe access point. It comes prewired from the factory.
8) What's the difference between a ringless meter socket and a ring-type one, and which do I need?
Ringless means the cover itself retains the meter, so there's no sealing ring around the meter rim. The U4163-XT-11-LI uses a single front lift-off screw cover over the meter. Which style you can install isn't your choice, it's the serving utility's: some require ringless, some require ring type. On Long Island this LISCO approved ringless build is the one specified.
9) What exact part number do I give my distributor for the Milbank 800A LISCO test switch socket?
Order Milbank U4163-XT-11-LI. The XT designates the test switch build and the LI suffix is the Long Island Lighting Company approved version, so dropping either character group gets you a different socket. It's a single model, no finish or size options to specify.
10) Is there a ground bar in the Milbank U4163-XT-11-LI, or do I have to add one?
Equipment ground is handled by a bonded ground strap in the enclosure. The insulating base behind the jaws is glass polyester. If your installation calls for a separate isolated neutral or a lug kit beyond the bonded strap, that's added hardware, not part of the socket.
11) I'm submitting on a government job and need the UNSPSC code for this meter socket.
The Milbank 800A ringless socket carries UNSPSC 39121102. That's the code for the line item on a public bid form or a punchout requisition, and it saves procurement classifying it by hand.
