Q: Can you Install Grace PESDs on High Current Circuits?

A: Yes, Grace PESDs can be installed on any amperage circuit, as long as within the Voltage Range of the PESD. They are not current carrying devices and are classified as Control Circuit Components. They are connected in parallel to the circuit, similar to a door-mounted power monitor or voltmeter for voltage monitoring. Though they can be connected to the three-phase power circuit, the current does not flow through the Grace PESDs.

This includes all devices in the Grace PESD family, including Voltage Indicators, Test Points, Combination Units, ChekVolt, and more.
