Eaton USTS131A301CH – Frequently Asked Questions

1) Does the Eaton USTS131A301CH 13-jaw meter socket carry 20A of load current, or is it only for instrument metering?
The 20A rating on the Eaton USTS131A301CH is an instrument rating, not a service entrance rating. It is an instrument rated socket, so the current comes through current transformers and the socket sees only the CT secondary current, up to 20A, at up to 600V. Do not use it as a self-contained socket on a 200A service; for that you need a conventional self-contained socket sized to the service.
2) Will a 13-jaw socket accept the meter my utility gave me?
13 jaws is the configuration for a three-phase, four-wire transformer rated meter, and that is what the Eaton USTS131A301CH is built for. A 4-jaw or 7-jaw self-contained meter will not land in it. Confirm with your utility that the meter they are setting is a 13-jaw transformer rated unit before you mount the can.
3) Does the Eaton instrument rated meter socket come with a test switch, or do I have to add one?
A test switch is already in the enclosure and factory wired. That means you can shunt the CT secondaries and test or swap the meter without opening the CT circuit, with no field wiring of the switch required.
4) Is the Eaton USTS131A301CH approved by Eversource in Connecticut?
Yes. The socket is listed as approved by Eversource in Connecticut, covering Connecticut Light and Power, Nstar, PSC New Hampshire, and Western Mass Electric. Catalog notes also show Iowa and Northeast approval. Utility acceptance lists change, so verify against your serving utility's current approved equipment list for the specific meter position.
5) What wall space do I need for the Eaton 13-jaw instrument meter socket?
Plan for an enclosure 20 in high, 12 in wide, and 4.36 in deep. At 27 lb it needs backing or masonry anchors, not drywall alone, and it is a two-hand lift to hold in position while you set the fasteners.
6) How many meters does the Eaton 13-jaw instrument socket hold? I have a multi-tenant building.
One. It is a single socket position, so each metered tenant needs its own enclosure and its own CT set. For a multi-unit building with several meters in one place you want a multi-position meter stack instead of individual instrument rated cans.
7) Can I use the Eaton USTS131A301CH on a 480V three-phase service?
The socket is rated 600V, so a 480Y/277V three-phase service is within its voltage rating. Because it is instrument rated, the service conductors do not pass through it, they pass through current transformers ahead of the meter.
