R Rock86 Senior Member Location new york Occupation Electrical Engineer / Electrician Nov 10, 2020 #1 Could anyone recommend a Ground Detector for a 480V ungrounded system, other than Bender Isometers? The ISO685 would do way more than what I need it to do, but I am having trouble finding anything which could handle a 480V input.
