Milbank U8215-RL – Frequently Asked Questions

1) What does the position number mean on a Milbank U8212-RL through U8216-RL ringless meter socket?
Position is the number of metering positions in the socket, and it is what separates the five part numbers in the U821x-RL family: U8212-RL is 2 position, U8213-RL is 3, U8214-RL is 4, U8215-RL is 5 and U8216-RL is 6. Every one is a 4 terminal, single phase, 100 amp continuous ringless socket. Pick the position count to match the number of metered units on the service, so a six-unit apartment building takes the 6 position U8216-RL.
2) Will a 4 terminal meter socket work for 120/240V single phase residential service?
Yes. Four jaws is the standard single phase, 3 wire configuration, and this Milbank socket is rated 1 phase, 60 hertz, 300 volts AC, which covers a 120/240V service. If the utility is metering a three phase service you need a 7 jaw socket instead, not this one.
3) What size service entrance conductors will land in this Milbank 100A meter socket?
Line side lugs take 6 AWG up to 350 kcmil, so typical 100 amp copper or aluminum SE conductors land without an adapter, and the range is generous enough for oversized aluminum runs. Load side is narrower at 6 AWG to 2/0. Terminals are lay-in type, which means you drop the conductor in rather than threading it through a closed barrel.
4) Does this meter socket include a main breaker or disconnect?
No. This is a meter-only socket with no main breaker and no bypass provision, so the disconnecting means has to be provided downstream in a separate panel or service disconnect. If your utility or AHJ requires a bypass lever for hot meter pulls, this is the wrong socket and you need a lever bypass version.
5) Can I use this socket for underground service, or is it overhead only?
Either. Cable entry is rated for overhead or underground, so the same part works for a weatherhead drop or a lateral from a pad transformer. It ships with a small hub opening, so an overhead installation needs a hub of the correct trade size for your riser conduit, ordered separately.
6) Can this Milbank socket be mounted outdoors on an exterior wall?
Yes. It is a surface mount enclosure with a Type 3R rating, which is the outdoor rating for rain, sleet and ice, and the body is G90 galvanized steel with a powder coat finish for corrosion resistance. It is not flush mount, so it sits proud on the wall rather than recessed into it.
7) What is the difference between a ringless meter socket and a ring-type one?
A ringless socket, like the Milbank U821x-RL family, uses a hinged or lift-off cover that fits over the meter and is sealed by the utility, with no separate locking ring around the meter rim. Ring-type uses a bolted or spring ring. The two are not interchangeable from the utility's standpoint, so check which style your serving utility specifies before ordering. Most utilities publish one or the other in their service handbook.
8) Is there a ground lug in this Milbank meter socket or do I add one?
A ground lug is included as the equipment ground provision, so the grounding electrode conductor and any bonding conductor can terminate in the can as-is. No separate ground bar kit is needed for a basic install.
9) How deep does this meter socket stand off the wall, and how tall is the enclosure?
The published figures are 16 inches for height and 4.5 inches for length. On a surface mounted can that depth dimension matters for clearance behind a meter reader's hand and for anything mounted beside it, so allow for it when laying out the service wall.
10) What insulation is used in the Milbank ringless socket jaw assembly?
Glass polyester backs the jaw assembly. It is a thermoset material used for the electrical isolation and heat tolerance around the meter jaws, which is what you want on a can sitting in full sun carrying 100 amps continuous.
