Can the Vigi modules be used at 480Vac? At 120Vac

Yes. The vigi module is fault-powered and uses a torroid to measure the vectorial difference between the currents in the cables passing through. The marked voltages refer to the operating range of the push-to-test button. Outside the marked range, the test button should not be used, and if used may not work properly.
