B-Line U122013 Eaton series CT meter socket and enclosure combo, 20 A, Ring type door /cover, Underground, ANSI 61 gray painted, #14-#10 load and line lug size, Galvanized steel, Surface mount, 13 jaws, 1 position, CT, NEMA Type 3R

No. The U122013 is built for an underground feed, so it is the wrong enclosure for an overhead service drop. If the utility is bringing the service in overhead, you need an overhead-fed meter socket instead.

Plan for a surface-mounted cabinet measuring 52 in height, 36 in width and 11 in length/depth. At 190 lb it is a two-person lift at minimum, and the structure behind it has to carry that load, so lag into blocking, masonry anchors or a strut frame rather than sheathing alone.

Yes. It is a NEMA Type 3R enclosure, which is the rainproof outdoor rating utilities normally accept for a wall-mounted meter cabinet. The shell is galvanized steel finished in ANSI 61 gray paint, and it carries a UL listing.

Thirteen jaws and a 20 A rating mark this as a CT-rated metering cabinet, not a self-contained socket. The meter itself only sees the 20 A secondary output of the current transformers, while the service conductors are metered indirectly. That is why the line and load lug size is #14-#10: those are the small CT secondary and voltage leads, not the service entrance cable. For a self-contained installation where the full service current passes through the socket, you need a 100 A, 200 A or 320 A socket with 4 or 5 jaws instead.

Ring type. The cover uses a sealing ring, which matters because many utilities specify one style or the other and will reject the other on inspection. Confirm with the serving utility which style they accept before ordering; if they require ringless, this is not the cabinet.

Yes, a removable test switch perch is included, so the utility's test switch can be mounted inside the cabinet without fabricating a bracket. Being removable, it also comes out of the way while you are landing the CT secondary and potential leads.

No. It is a 1-position cabinet, so it handles a single metered service. For multi-family or strip retail where several tenants need separate meters, you need a multi-position metering pack or one cabinet per service.

The lug provisions in this cabinet are sized #14-#10, which covers the current transformer secondary leads and the potential wiring, not the service entrance conductors. Current transformers are sized and, in most jurisdictions, furnished by the serving utility to match the service, so they are specified separately from the enclosure.
