Eaton USTL132A298CH – Frequently Asked Questions

1) Is the Eaton 13-jaw meter socket self-contained or does it need current transformers?
It's a transformer rated, instrument rated socket, so it is not self-contained. The 20A rating is the instrument circuit rating, not the service load. You feed it from current transformers (and potential transformers where the utility requires them) on the primary side, and the socket carries only the CT secondary and voltage circuits to the meter. If you're metering a service directly without CTs, you need a self-contained socket instead.
2) What does the 13-jaw configuration on this Eaton poly-phase socket support?
Thirteen jaws is a poly-phase instrument-rated arrangement, used where the meter needs all three current circuits plus the voltage circuits brought up separately rather than the 6 or 8 jaws you see on a self-contained poly-phase socket. Match the jaw count to the meter the utility is setting; a 13-jaw meter will not seat in an 8-jaw socket and the reverse is also true.
3) Does this Eaton meter socket come with the test switch already wired?
Yes. The test switch ships factory wired into the socket, so the CT secondary and voltage leads are already landed. That's the switch a technician uses to short the CTs and lift the meter without opening the secondary circuit. You're still making the CT and voltage terminations into the enclosure, but the switch-to-jaw wiring is done.
4) Will this Eaton socket work on a 480V three-phase service?
Yes, it's rated 600 Vac, which covers 480Y/277 and 480 delta metering installations as well as 208Y/120. The voltage rating applies to the instrument and potential circuits landing in the socket; primary current still runs through the CTs outside the can.
5) Is this Eaton meter socket approved by my utility?
Eaton catalogs this one as Iowa and Northeast approved, and it carries a UL Listing. Utility acceptance is always per serving utility, so confirm the catalog number against your utility's approved meter socket list before it goes on the wall, since a non-listed socket gets rejected at inspection even when it meets code.
6) How much wall space do I need for this Eaton instrument rated meter socket?
Plan for an enclosure measuring 21.75 x 12.63 x 5.75 inches, at 23.5 lb. At that weight it needs to land on structure or unistrut rather than drywall anchors, and leave clearance at the meter face for the utility to set and seal the meter.
7) What is the Eaton catalog number for the 13-jaw instrument rated socket with test switch?
Order it as Eaton USTL132A298CH. That number covers the 13-jaw poly-phase instrument rated socket, 600V, 20A, with the test switch factory wired.
8) Can I use this for tenant submetering in a commercial building?
It suits submetering where loads are large enough to need CTs, which is the usual case on a commercial or multi-tenant house panel. The socket accepts a poly-phase instrument-rated meter and the factory test switch lets a tech verify or swap the meter without dropping the tenant's service. For small single-phase tenant loads, a self-contained socket is the simpler and cheaper route.
