Milbank U4497-WL – Frequently Asked Questions

1) Is the Milbank U4497-WL a self-contained meter socket or does it need current transformers?
The U4497-WL is a transformer-rated socket, not self-contained. Its 20 continuous ampere rating is the meter circuit rating, not the service size, and the 13 terminal jaw configuration is the standard 3-phase CT metering arrangement. It pairs with utility-supplied current transformers on the service conductors. If you need a socket that carries the full service current directly, this is the wrong type.
2) What wire size can I land in the Milbank U4497-WL meter socket?
Both line and load terminals take 14 through 2 AWG, using single mechanical terminals. Since this is a CT-rated socket, those are the metering and voltage leads coming from the CT cabinet, not service conductors. There are also two barrel ground lugs for equipment grounding.
3) Can I mount this Milbank ringless socket outdoors on an exterior wall?
Yes. The U4497-WL enclosure is UL Listed and rated Type 3R for outdoor use, built from G90 galvanized steel with a powder coat finish, and it surface mounts. Cable entry works for either overhead or underground service.
4) Does the Milbank U4497-WL include a main breaker or disconnect?
No. This is a meter socket only, with no main breaker and no receptacles, one meter position. You will need a separate service disconnect downstream, which is standard practice on CT metering where the disconnect and overcurrent protection sit in adjacent gear.
5) Will a Milbank U4497-WL work on a 480Y/277V three-phase service?
Yes, within rating. The socket is rated 600 volts AC at 60 hertz on three phase, which covers 480Y/277V and 208Y/120V three-phase systems. Glass polyester insulation carries the jaws at that voltage class.
6) What does the lever bypass on this Milbank socket actually let the utility do?
The lever bypass test switch provision lets a meter tech isolate and pull the meter for testing or replacement without dropping the customer's service. Many utilities require bypass on transformer-rated metering installations, so check the local utility's approved equipment list before you order, since a non-bypass socket will fail inspection where bypass is specified.
7) What size conduit hub does the Milbank U4497-WL come prepped for?
It is furnished with a 1 inch hub closing plate, so the top entry is set up for 1 inch conduit carrying the metering conductors from the CT cabinet. If your run calls for a larger raceway you will need the corresponding hub or plate, not this one.
8) What is the difference between a ringless meter socket and a ring-type one, and which do I need?
A ringless socket like the U4497-WL uses a one-piece cover that slips over the enclosure and is secured by the utility's seal, with no separate sealing ring. Ring-type sockets use a locking ring around the meter. Which one you install is dictated by the serving utility, not by preference, so confirm with them before ordering. This unit is the ringless version.
9) What part number do I give my supplier for this Milbank CT meter socket?
Order Milbank U4497-WL. It sits in Milbank's CT80 product family and is the 13 terminal ringless socket with 1 inch hub and lever bypass test switch provision.
