Milbank U4667-G-8043 – Frequently Asked Questions

1) How much wall space do I need to mount this 480A Milbank meter socket?
Plan for a footprint of 20-1/4 inches wide by 34 inches high, with 6 inches of depth off the wall. It is a surface mount enclosure, so the back flange lands flat against the structure and you need clear working space in front per the code rules for your service.
2) Can this meter socket be installed outdoors?
Yes. The enclosure is UL Listed and rated Type 3R, which is the standard outdoor rating for rain and sleet on service equipment. The shell is G90 galvanized steel with a powder coat finish for corrosion resistance.
3) What are the line side terminations on this socket and what conductors can I land?
Line side lands on 1/2 inch studs, which is a bolt-in connection rather than a set screw lug, so you are landing compression lugs or bus onto the stud. Equipment grounding is handled by two barrel ground lugs in the enclosure. Bolt-in studs are the reason this unit carries the 480 amp continuous rating at 600V.
4) What does link bypass mean on a meter socket, and do I need it?
Link bypass gives you bolted copper links inside the socket that carry load around the meter, so the meter can be pulled and changed without dropping power to the building. Utilities commonly require it on large commercial services, and tenants in occupied buildings want it. If your utility specifies a lever (horn) bypass instead, this unit will not satisfy that spec.
5) Can I run the service underground into this socket, or is it overhead only?
Either works. The socket is built for overhead or underground cable entry and ships with a 3-1/2 inch hub for the top feed. For an underground lateral you come in through the bottom of the enclosure and the hub position stays closed off up top.
6) Can I meter two tenants from this Milbank socket?
No. It is a single meter position. For multi-tenant metering you need a multi-position socket or a meter stack, not this unit.
7) Is a bolt-in meter socket different from a ringless or jaw-type socket?
Bolt-in means the line and load conductors bolt to studs inside the can instead of clamping into lugs, which is what high-amperage commercial sockets use. This Milbank unit is a bolt-on type rated 480 amps continuous with 1/2 inch line side studs. For smaller residential and light commercial services at 200 amps or less, a standard lug-type socket is the usual choice.
8) What insulates the jaws and bus in this Milbank meter socket?
Glass polyester is used for the internal insulation, the standard dielectric base material on commercial sockets at this rating. It holds up to the heat of a 480 amp continuous load better than plain thermoplastic.
