Milbank U4979-XL-SMECO – Frequently Asked Questions

1) Is the Milbank U4979-XL-SMECO meter socket approved for Southern Maryland Electric Cooperative service?
The U4979-XL-SMECO is built to the Southern Maryland Electric Coop specification, which is why the SMECO suffix is on the model number. If you are setting a service in another utility's territory, order the socket on that utility's approved list instead, since meter socket acceptance is utility specific.
2) Will a 4 terminal 200A ringless socket work for a 120/240V single phase residential service?
Yes. Four jaws is the standard configuration for a 120/240V single phase, 3 wire self contained residential or light commercial service, and this Milbank socket is rated 200 continuous amperes, 1 phase, 600VAC max, 60 Hz. For a single phase network or a three phase service you need a different jaw count, not this one.
3) What wire size can I land in this Milbank 200A meter socket?
Both line and load terminals take 6 AWG through 250 kcmil, using double mechanical lugs. That covers the usual 2/0 copper or 4/0 aluminum used on a 200A dwelling service, and the double-barrel terminals let you land two conductors per phase where the utility allows it.
4) Can this meter socket be used for an underground service lateral, or is it overhead only?
Either. The U4979-XL-SMECO accepts overhead or underground cable entry, and it ships with a small closing plate covering the hub opening. For an overhead drop you remove the closing plate and fit the hub size the utility calls for; for an underground lateral the plate stays in and you bring the conduit in through the bottom.
5) Does this Milbank ringless socket include a main breaker or a bypass?
No. It is a socket only, with no main breaker and no bypass provision, so overcurrent protection has to live in the panel or in a separate service disconnect downstream. If your utility requires a lever bypass for hot meter pulls, or you want the main breaker in the same can, you need a combination meter-main or a bypass-equipped socket instead.
6) Is this meter socket rated for outdoor mounting on an exterior wall?
Yes. The enclosure is Type 3R and UL Listed, which covers outdoor exposure to rain, sleet and ice. The shell is G90 galvanized steel with a powder coat finish, and the jaw block is glass polyester. Type 3R is not washdown or dust-tight, so it is for normal exterior wall mounting, not hosedown or heavy marine spray service.
7) What does ringless mean on a meter socket, and do I need a ring-type one instead?
Ringless means the socket uses a lift-off or hinged utility-sealed cover rather than a separate sealing ring clamping the meter in place. The utility decides which style it will accept, and the two are not interchangeable in the field. This Milbank unit is ringless with a small closing plate, built to the SMECO spec, so verify ringless is what your serving utility allows before setting it.
8) Is there a grounding provision in this socket, or do I have to add a ground bar?
A ground lug is provided in the can for the equipment grounding or grounding electrode conductor, so no separate grounding kit is needed for a single connection. If you need to land multiple grounds or a neutral bonded bar for several conductors, you will want to add a ground bar kit.
9) Can I meter two apartments with this Milbank socket?
No. It is a single position socket, one meter only, and it has no receptacles. For a duplex or a multi-unit building you need a two-position socket or a multi-gang meter stack with one position per tenant.
10) Is a 200A socket adequate if the panel downstream is 150A or 175A?
Yes. The socket is rated 200 continuous amperes, so it covers any service sized at or below that, including 150A and 175A installations. It carries no overcurrent device itself, so the service rating is set by the main breaker or fuses you install downstream, not by the socket.
