Milbank S4664-X-8416 – Frequently Asked Questions

1) Does the Milbank S4664-X-8416 meter socket include a main breaker or disconnect?
No. The S4664-X-8416 is a socket only, with no main breaker (zero main breakers) and no receptacles. If the service needs overcurrent protection or a disconnect at the meter, you order that separately as a downstream main or a meter-main combination unit instead.
2) Will a 4-terminal 480A Milbank socket work on a 3-phase service?
No. The S4664-X-8416 is a 1-phase, 4-terminal (4-jaw) socket rated 300 VAC, 60 Hz. A three-phase service needs a 7-jaw socket. Confirm the jaw count and phase your utility specifies for the meter before ordering, because the jaw configuration is not field-convertible.
3) What does link bypass mean on a meter socket, and when does the utility require it?
Link bypass puts removable copper links in the socket so a meter tech can carry load around the meter and pull it without dropping service to the building. On the Milbank S4664-X-8416 that bypass is built in. Many utilities mandate link or lever bypass on larger commercial and multi-family services so metering can be swapped live; if your utility's spec sheet calls for a manual bypass, this is the configuration that satisfies it. On smaller residential services a no-bypass socket is usually accepted.
4) Can this Milbank 480 amp socket be mounted outdoors on an exterior wall?
Yes. It is a surface-mount enclosure with a Type 3R rating, which covers outdoor use against rain and sleet, and the body is G90 galvanized steel with a powder coat finish. Note it is Non UL Listed, so if your inspector or utility requires a UL listed socket, specify a listed model instead.
5) Can I feed this socket from underground, or is it overhead only?
Either. The S4664-X-8416 accepts overhead or underground cable entry and ships with a large closing plate, so you can cut and fit the hub you need for an overhead weatherhead drop or leave it closed and bring conduit in from below for an underground lateral. The hub itself is a separate item sized to your conduit.
6) What size line-side lugs or terminals does this Milbank socket use?
The line side uses 1/2 inch studs, so your service conductors land on bolt-on lugs or compression terminals drilled for a 1/2 inch stud rather than screw-type set lugs. Order lugs matched to your conductor size with a 1/2 inch bolt hole. There is also a triplex ground provision in the enclosure.
7) How much wall space do I need for this 480A single position meter socket?
Plan the opening around 6 x 13.813 x 26 inches (length x width x height). It mounts on the surface, so you need a flat, solid backing at least that footprint plus working clearance in front of the meter per code.
8) Is 480 amps the continuous rating or a short-time rating on this socket?
480 amps is the continuous ampere rating, meaning it is rated to carry that load indefinitely rather than as a momentary peak. The voltage ceiling is 300 VAC at 60 Hz single phase, so it suits 120/240V services, not higher-voltage systems.
9) How many meters can be installed on the Milbank S4664-X-8416?
One. It is a single position socket, so it serves one metered service. For a multi-family building where each unit is separately billed, you need a multi-position meter stack or ganged sockets, not this unit.
10) What keeps the live parts isolated inside this bolt-on meter socket?
Glass polyester is used as the insulating material for the jaw assembly and bypass hardware, a thermoset that holds up to the heat and mechanical stress of a 480 amp continuous load better than general-purpose plastics. The jaws themselves are a 4-terminal bolt-in design rather than a ringed clip style.
