Milbank UC3913-RL-WC-11 – Frequently Asked Questions

1) Does the Milbank UC3913-RL-WC-11 meter socket carry the service current, or is it for CT metering only?
The UC3913-RL-WC-11 is a 20 continuous ampere, 600 VAC socket. That 20 A is the instrument rating, not a service rating, and the wire ranges back it up: both line and load sides land 12 to 10 AWG only. It has no bypass provision and no main breaker. This is the CT-rated metering enclosure that sits downstream of current transformers, not a socket you pull service conductors into.
2) Will a 13 jaw meter socket take my utility's meter, or do I need a 7 jaw?
Thirteen terminals is a 3-phase CT metering jaw configuration with a single meter position. A standard 7 jaw self-contained 3-phase meter will not seat in it, and neither will a 4 jaw single-phase meter. Confirm with the serving utility that they are setting a 13 jaw transformer-rated meter on this point before you mount it, because the jaw count is fixed and cannot be changed in the field.
3) Can this Milbank ringless socket be mounted outdoors on an exterior wall?
Yes. The enclosure is Type 3R and UL Listed, which is the rainproof outdoor rating for wall-mounted electrical gear. Body is G90 galvanized steel with a powder coat finish. It is a surface mount unit, so it lands flat on the wall or a strut rack rather than being recessed into it.
4) How much wall space do I need for the Milbank UC3913-RL-WC-11?
Plan for a footprint of 5L x 12W x 20H inches. Height is 20 inches and width 12 inches, with 5 inches of depth off the wall. Leave working clearance in front per your local code for the meter and the test switch.
5) Is the test switch already wired in, or do I have to field wire it?
The test switch comes prewired from the factory on the UC3913-RL-WC-11, so the CT secondary and potential leads land on the switch rather than on you building the harness. Your field work is bringing the CT secondaries and potentials into the can and terminating at the single mechanical terminals.
6) Does the small hub opening let me come in from overhead, or do I need underground?
Either. Cable entry is rated for overhead or underground on this socket, and it ships with a small hub opening plus a cover, so you can fit a hub for an overhead riser or plate it off and bring conduit in from below. If the utility requires a specific hub size, verify the small hub opening matches before you set the can.
7) What is the ringless design on this Milbank socket, and does it change how I install it?
Ringless means there is no sealing ring clamping the meter to the socket. Instead the utility's sealable cover holds the meter in place, which is what most utilities in ringless territories require. Check which style your serving utility specifies, because a ringless can cannot be converted to ring-type in the field.
8) Will this Milbank socket work on a 480Y/277 three phase service at 60 Hz?
Yes on the voltage and frequency. The socket is rated 600 volts AC at 60 hertz, three phase, which covers 480Y/277 and 208Y/120 systems. The limiting factor is not the voltage but the metering type: it is a 20 A transformer-rated can, so the service current has to be handled by CTs ahead of it.
9) Is there a ground point in this meter socket, or do I add one?
A ground lug is provided for the equipment ground, so you bond directly inside the can. Internal insulation is glass polyester. There are no receptacles and no breaker positions in this enclosure, so overcurrent protection has to live elsewhere in the installation.
10) I need the exact part number for a Milbank 13 terminal ringless CT socket with a small hub and cover for a submittal.
The model is Milbank UC3913-RL-WC-11: 13 terminal, ringless, small hub opening with cover, test switch prewired, single meter position, Type 3R, UL Listed. UNSPSC is 39121102 if your procurement system wants a commodity code.
