B-Line 122013 Eaton series CT meter socket and enclosure combo, 20 A, Ring type door /cover, Overhead and Underground, ANSI 61 gray painted, #14-#10 load and line lug size, Galvanized steel, Surface mount, 13 jaws, 1 position, CT, NEMA Type 3R

The B-Line 122013 is a current transformer (CT) rated meter socket and enclosure combination, so the utility's metering is done through external current transformers rather than passing full load current through the socket itself. That is why the socket is only rated 20 A: it carries the CT secondary and potential circuit, not service current. A self-contained socket would carry the whole load through the jaws and be rated 100, 200 or 320 A. If your utility has specified CT metering for a large service, this is the type you need; if the meter is to be wired directly in the service conductors, you want a self-contained socket instead. The 122013 has 13 jaws in a single meter position.

Yes. The enclosure is NEMA Type 3R, which is the standard outdoor rating for rain and falling debris, and it is galvanized steel finished in ANSI 61 gray paint. It surface mounts, so it goes on a wall or a structural backing rather than being flush set into it.

It measures 42 inches high, 36 inches wide and 11 inches deep, and it weighs 160 lb. That is not a one-man lift onto a wall. Plan for two people or a lift, and back it with structure that will carry 160 lb plus conductor weight, since it is surface mounted.

The line and load lugs are sized for #14 through #10 conductors. Those are the CT secondary and potential leads, not service entrance conductors, which is consistent with the socket's 20 A metering rating. If you are trying to land large service conductors on lugs inside the socket, this is the wrong assumption about how the cabinet is wired.

Ring type. The cover uses a sealing ring rather than a ringless lift-off design, so the utility seals the ring at the meter. Many utilities specify one or the other by name, so match the ring type callout on your utility's approved equipment list before ordering.

Either one. The 122013 is built for overhead and underground feed, so you can bring conductors in from a weatherhead above or from a lateral below without changing enclosures.

It includes a removable test switch perch, which is the mounting provision the utility uses for a test switch. The perch is part of the enclosure; the test switch itself is typically supplied or specified by the serving utility.

Yes, the 122013 carries UL certification. For a metering installation you will still need it to appear on your serving utility's approved list, since utilities approve socket models individually in addition to the UL listing.

One. It is a single position socket, so it meters one service. A multi-tenant building needing separate metering per unit requires a multi-position socket or multiple enclosures.

Order it as B-Line 122013, an Eaton B-Line series CT meter socket and enclosure combination, 13 jaw, 1 position, Type 3R, ring type cover, ANSI 61 gray. The manufacturer part number is 122013.
