Milbank U7420-RL – Frequently Asked Questions

1) Will a Milbank U7420-RL 7-jaw socket work for a 3-phase 4-wire service?
The U7420-RL is a 7-terminal (7-jaw) single-position socket built for 3-phase service at 600V AC, 60 Hz, 200 continuous amps. The 7-jaw arrangement is the standard pattern utilities specify for 3-phase 4-wire network and wye metering. If your utility has approved a 5-jaw or 4-jaw socket for a single-phase or 3-wire delta service, this is not the right unit; the jaw count has to match the meter the utility sets.
2) Is this meter socket set up for overhead service or underground lateral?
Overhead. The U7420-RL is configured for overhead cable entry with a small hub opening in the top, so it takes a conduit hub or weatherhead riser feed. For an underground lateral you want a socket with a bottom-fed or lugless/underground configuration instead, since there is no hub provision on the bottom of this unit.
3) Will 4/0 aluminum or 250 kcmil copper service conductors fit the lugs?
Yes. Both the line and load terminals on the U7420-RL accept 6 AWG through 350 kcmil, so 4/0 aluminum and 250 kcmil copper both land without a reducer. They are lay-in type terminals, which means you drop the conductor in from the front rather than threading it through a closed barrel.
4) Does this socket include a main breaker or a bypass lever?
No on both counts. The U7420-RL is a socket only, with no main breaker and no bypass provision, so overcurrent protection has to live downstream in your service disconnect or panel. If your utility requires a lever bypass for hot meter changes, this unit will not pass their inspection and you need a bypass-equipped socket.
5) Does the U7420-RL come with a hub, or do I order that separately?
The socket ships with a small hub opening closing plate, not a hub. You size and order the conduit hub to match your service raceway separately. The opening is the small-hub size, so confirm the hub you buy is rated for that opening before you cut in.
6) Can this Milbank ringless socket be mounted outdoors on an exterior wall?
Yes. It is a surface-mount, Type 3R rated enclosure, which covers rain, sleet and falling water on an outdoor wall. The shell is G90 galvanized steel with a powder coat finish for corrosion resistance. Type 3R is not washdown or dust-tight, so an interior industrial location with hose-down or heavy airborne dust calls for a higher enclosure type.
7) How much wall space do I need for the U7420-RL, and how far does it stand off the wall?
Plan on 10 inches wide by 18.5 inches high, with a depth of 4.844 inches off the mounting surface. That depth matters where the socket sits in a recessed alcove or behind a gate swing, and the 18.5 inch height drives where you set it so the meter center lands in the utility's required reading window.
8) What is the difference between a ringless meter socket and a ring-type one, and which do I need?
A ringless socket uses a hinged or lift-off cover that the utility seals directly, with no separate sealing ring around the meter. A ring-type socket needs a locking ring to hold the meter cover on. They are not interchangeable: the utility serving the building specifies which style it will accept, and the covers do not swap between them. The U7420-RL is the ringless version, so order it only where ringless is the approved style in that territory.
9) Is this meter socket UL Listed for a permit inspection on a commercial job?
Yes, the U7420-RL is UL Listed and carries a Type 3R enclosure rating. Those are the two lines an inspector or a spec reviewer typically looks for on an outdoor service socket. Keep in mind it has no integral overcurrent device, so the service disconnect requirement is satisfied elsewhere in your assembly.
10) Can I meter two tenants with one of these?
No. The U7420-RL is a single-position socket with one meter mounting, no receptacles and no bypass. For a multi-tenant building you need a multi-position meter stack or a group metering enclosure sized to the number of tenants. For standardizing across a property, one of these per service point is the pattern, and the family code is MD7T with the orderable part number U7420-RL.
11) Is there a ground lug for the grounding electrode conductor, or do I add a kit?
A ground lug is provided as the equipment ground connection in the U7420-RL, so you do not need a separate bonding kit for the enclosure. Jaw insulation is glass polyester.
