Milbank U8215-XL-KK-BLG – Frequently Asked Questions

1) Will a Milbank U8212-XL ringless meter socket accept my 4/0 aluminum service entrance conductors?
Line side lugs on the U821X-XL sockets take 6 AWG through 350 kcmil, so 4/0 lands with room to spare. Load side is a smaller range, 6 AWG through 2/0 AWG, so size the conductors going out to the panel accordingly. That load side limit is the one that catches people running oversized feeder for voltage drop on a long run.
2) Does the Milbank 100 amp ringless meter socket come with a main breaker?
No breaker in it. These are meter-only sockets, no main breaker and no receptacles, so the service disconnect and overcurrent protection have to come from a separate panel or a disconnect downstream. If you need meter and main in one enclosure, you want a meter-main combination unit instead of this one.
3) What is the difference between the 2 position and 6 position Milbank U821 meter sockets?
The position number is the lever bypass / jaw position count on the socket, and it runs 2, 3, 4, 5, and 6 position across the U8212-XL through U8216-XL models. Everything else is common: 4 terminal ringless, 100 continuous amps, 300 VAC, single phase. Your utility usually dictates which position count they will accept, so check their approved meter socket list before ordering.
4) Can this Milbank meter socket be mounted outside on an exterior wall?
Type 3R rated and UL Listed, so outdoor surface mounting on an exterior wall is what it is built for. The enclosure is G90 galvanized steel with a powder coat finish for corrosion resistance. Type 3R protects against rain and sleet, not submersion or washdown, so keep it out of locations subject to direct hose spray.
5) What does the KK suffix mean on a Milbank U8214-XL-KK meter socket?
KK is the horn bypass option. A horn bypass lets the utility bypass the meter to pull or change it without dropping power to the customer. The plain U8214-XL has no bypass; U8214-XL-KK adds horn bypass; U8214-XL-KK-BLG adds horn bypass plus the barrel lock provision. If your utility requires bypass on residential services, the plain version will get rejected at inspection.
6) Is a ringless meter socket the right choice, or do I need a ring type?
Ringless is a utility preference, not a performance difference. A ringless socket uses a hinged cover secured by the utility's seal instead of a separate sealing ring around the meter. Many utilities have standardized on ringless; others still require ring type and will not energize a ringless can. Confirm with the serving utility first, because the two are not interchangeable in the field. The Milbank U821X-XL family is ringless, 4 terminal, single phase.
7) Will a 4 terminal socket work for my 3 phase panel?
No. This is a 4 terminal single phase socket, correct for 120/240V single phase services only. A three phase service needs a 7 jaw socket. Ordering this one for a three phase commercial service means the meter will not fit the jaws.
8) Do I need the BLG barrel lock version of the Milbank ringless socket?
Order the BLG version if your utility locks meter sockets with a barrel lock. That option supplies a 7/8 inch knockout and an angle bracket for the barrel lock provision. Utilities that seal with a wire seal or a standard ring lock do not need it. It is available on the 2, 3, 4, 5, and 6 position sockets, all paired with horn bypass, for example U8213-XL-KK-BLG and U8215-XL-KK-BLG.
9) Will this Milbank socket work for an underground service lateral, or only overhead?
Both. Cable entry is rated for overhead or underground, so the same socket handles a drop from a weatherhead or a lateral coming up from below. The Small Closing Plate configuration covers the hub opening on top when you are fed from underground and do not need a hub.
10) How much wall space does the Milbank U821 meter socket need?
Figure 16 inches for the enclosure height and 4.5 inches of length. Surface mount, so plan the working clearance in front of it per code and leave room to swing the cover. Meter height above finished grade is set by the serving utility, typically in the 4 to 6 foot range, so confirm their standard before you set the backing.
11) Are the terminals on this Milbank socket lay-in, and does that matter for installation?
Lay-in terminals, which means the conductor drops into an open lug rather than threading through a closed hole. That saves real time on a service change when you are working with stiff 350 kcmil line conductors in a tight can. Glass polyester insulation carries the jaw assembly.
