B-LINE U121816 – Frequently Asked Questions

1) What size wall space do I need for the Eaton B-Line U121816 CT meter socket enclosure?
Plan for a surface-mounted enclosure measuring 52 inches high, 24 inches wide, and 11 inches deep. It weighs 125 pounds empty, so a solid backing (block, concrete, or blocked-out studs) and two people for the set are realistic on this one. It mounts to the surface of the wall, not flush into it.
2) Can the B-Line U121816 meter socket be installed outdoors?
Yes. It is a NEMA Type 3R enclosure in galvanized steel with ANSI 61 gray paint, which is the standard outdoor rating for rain and falling water on service equipment. The unit is UL listed.
3) Is the U121816 for an overhead service drop or an underground lateral?
Underground only. The U121816 is built as an underground-feed CT meter socket, so the service conductors come up into the enclosure from below. If the utility is bringing an overhead drop to the building, you need an overhead-feed version instead.
4) What does the 20 A rating mean on a CT meter socket like the U121816?
This is a CT-rated socket, not a self-contained one. The 20 A rating is the secondary rating of the metering circuit fed from the current transformers, not the service size. The actual service current passes through the CTs; the socket sees only the scaled secondary output. That is why the line and load lugs accept small #14 to #10 conductors rather than service-size cable.
5) Does this Eaton B-Line meter socket have a ringless or ring-type cover?
Ring type. Utilities specify ring versus ringless and they are not interchangeable, so confirm with the serving utility which style they accept before you set the can. If their standard is ringless, this unit will be rejected at inspection.
6) What wire size do the lugs in the B-Line U121816 take?
Line and load lugs are sized for #14 through #10 conductors. That covers the usual CT secondary and voltage-sense wiring run into a CT cabinet. Anything larger will not land in these lugs.
7) Is the U121816 a 6-jaw socket, and what service does that suit?
Six jaws, single position. Six-jaw CT sockets are the common arrangement for three-phase transformer-rated metering. One position means one meter per enclosure, so a multi-tenant building needs one unit per metered service.
8) Does the U121816 CT cabinet come with a place to mount a test switch?
It includes a removable test switch perch, so the utility's meter test switch has a factory mounting point inside the cabinet. The perch comes out if the utility does not use one.
9) Do the current transformers come with the B-Line U121816?
No. This is the CT meter socket and enclosure combination itself, 6 jaw, 1 position, with the removable test switch perch. The current transformers are normally supplied and installed by the serving utility, and the meter itself is utility-supplied as well.
