Milbank TS07-0105 – Frequently Asked Questions

1) Will a Milbank 7-pole test switch work on a 480V three-phase metering installation?
Yes. The Milbank TS07 test switch is rated 600 volts AC, so it covers 480V three-phase service as well as 120/208 and 277/480 systems. Current rating is 20 amperes at 60 Hertz, which suits instrument-rated (CT/PT) metering circuits rather than direct load switching.
2) Does the Milbank TS07 metering test switch come with an enclosure or do I need to supply one?
It ships as a bare switch with no enclosure, so you mount it inside the meter cabinet, metering panel, or a separate box you provide. Plan the cutout around a body measuring 3.5 in and 2.906 in per the published height and length.
3) What is the difference between the TS07-0049, TS07-0105, TS07-0106 and TS07-0431 test switches?
All four are 7-pole, 20A, 600V Milbank test switches; the trailing digits are the configuration code that identifies the pole arrangement and wiring build. Order by the full part number the utility or metering spec calls out, since the four are not interchangeable on the same drawing.
4) Is the Milbank 7-pole metering test switch UL Listed for a commercial service installation?
Yes, it is UL Listed, which is what most utilities and inspectors want to see on metering accessories installed in a commercial or industrial service.
5) How do the wires land on this Milbank test switch - screw terminals or studs?
Stud connections. You terminate with ring lugs onto the studs rather than pushing conductors into a clamp terminal, so allow for lug prep on the CT secondary and potential leads when you cut wire lengths.
6) Why is a 7-pole test switch used instead of a 6-pole on a three-phase meter?
Three-phase metering needs three current pairs plus three potential circuits, and the seventh pole gives you the extra position many utility drawings require, typically a neutral or spare potential blade. The Milbank TS07 carries seven poles; if your metering diagram only shows six positions, buy the switch that matches the diagram rather than leaving a pole unused.
7) Can I use this test switch to disconnect load, or is it only for meter testing?
It is a metering accessory, built to isolate and short CT secondaries and open potential leads so a meter can be tested or swapped without dropping service. The 20A rating is an instrument rating, not a load-break switch rating, so do not use it as a disconnecting means for branch or feeder load.
8) Will a bronze test switch hold up in a damp outdoor meter socket environment?
The current-carrying parts are bronze alloy, chosen for conductivity and corrosion resistance, and the insulating body is non-metallic. Since the switch itself has no enclosure, weather protection comes from the cabinet you mount it in, not from the switch.
