Milbank TS10-0110 – Frequently Asked Questions

1) Will a Milbank TS10 test switch work on a 480V three-phase metering install?
Yes. The Milbank TS10 10-pole test switch is rated 600 volts AC at 60 hertz, so it covers 480V three-phase service metering along with 120/208 and 277/480 systems. Current rating is 20 amperes, which is well above the secondary current a CT-rated meter installation puts through the switch.
2) How much panel space do I need for a Milbank 10-pole metering test switch?
Plan for a footprint of 9.5 inches wide, 3.5 inches high and 2.906 inches deep. It ships with no enclosure, so it mounts inside a meter socket, CT cabinet or instrument panel you already have, and you need to allow depth behind the mounting surface for the stud terminals and wiring.
3) Does the Milbank TS10 test switch come with its own enclosure or box?
No enclosure is supplied. The TS10 is an open switch assembly meant to be mounted into an existing meter socket, CT cabinet or metering panel. Order a cover version if you want the switch itself shielded, but you still need a cabinet or panel to house it.
4) What is the difference between the Milbank TS10 with cover and without?
Two of the configurations are offered both ways: TS10-0109 and TS10-0110 each have a matching cover version, TS10-0109-WC and TS10-0110-WC. The cover is a protective shield over the switch blades and stud terminals, guarding against accidental contact and dirt once the switch is live. The 0111 and 0112 configurations come without the cover option.
5) What do I have to specify when ordering a Milbank TS10 test switch?
Pick the configuration code. Four are built: 0109, 0110, 0111 and 0112, ordered as TS10-0109, TS10-0110, TS10-0111 and TS10-0112. On the 0109 and 0110 you also choose covered or uncovered, which adds the WC suffix. Utility metering departments usually dictate the configuration code on their approved-equipment list, so pull it off the utility spec before ordering.
6) Is the Milbank TS10 metering test switch UL Listed for a commercial service?
UL Listed, which is what most AHJs and utility metering departments require before a test switch goes into a commercial or industrial service. That listing sits alongside the 600V AC, 20A, 60Hz ratings for the installation submittal.
7) How do the wires land on a Milbank TS10 test switch, screw terminals or studs?
Stud connections. Each pole terminates on a threaded stud, so conductors land on ring-tongue lugs under a nut rather than into a screw clamp. Crimp your CT secondary and potential leads with ring terminals sized to the stud before you get to the panel, and bring the right nut driver.
8) Why 10 poles on a metering test switch, and is that enough for my install?
Ten poles gives you separate switched paths for the current and potential circuits of a polyphase meter installation, typically three CT current pairs plus the potential legs and neutral on a three-phase four-wire service. That is the common count for utility-grade transformer-rated metering. If your install only needs current shorting on a single-phase service, a smaller pole count is the cheaper route.
9) Can I change a meter without dropping power to the tenant using a TS10 test switch?
That is what the switch is for. A 10-pole instrument-rated test switch lets you short the CT secondaries and open the meter potential circuits so the meter can be pulled, tested or replaced while the service stays energized and the tenant stays on. Rated 600V AC, 20A, 60Hz for the metering circuits it sits in.
10) Can I add a Milbank test switch to an existing meter socket that does not have one?
Yes, provided there is room. The TS10 needs 9.5 by 3.5 by 2.906 inches of mounting space and lands on stud terminals, so it retrofits into a CT cabinet or auxiliary trough on an existing transformer-rated installation rather than into the meter socket jaws themselves. Self-contained sockets without CTs generally have neither the space nor the circuits for it.
11) What is the Milbank TS10 test switch made of, and will it hold up in a damp outdoor CT cabinet?
Current-carrying parts are bronze alloy, which resists corrosion and keeps contact resistance stable over years of make-and-break. The insulating barriers between poles are non-metallic. Since no enclosure is supplied, the environmental protection comes from whatever cabinet you mount it in, so an outdoor location needs a rated cabinet around it.
12) What UNSPSC code should I use for a Milbank metering test switch on a purchase order?
UNSPSC 39122215 covers the Milbank TS10 instrument-rated metering test switch. That is the code to drop into a government, healthcare or institutional procurement system when the requisition needs a commodity classification.
