Is there a problem with leaving conductors connected to the load side of a GFPE breaker in the off position, and meggering them? Could it damage the breaker?
First link is dead. Second link shows a sticker that says PASSED and an 800 number, call that if you have any questions I suppose. To the right is a sticker that says 600A.https://www.dropbox.com/s/1rkwz3117qnu2le/2015-10-23 16.16.04.jpg?dl=0

This is the breaker is question. An aside question: is it legal to supply a 400A rated switch from this breaker?
That trip unit is a "Microversatrip Plus" There are no voltage connections, only CTs. I've tested tons of those at 1kV, you'll be fine.
Our analog meggers will flutter when the battery is low, I would eliminate test error first.
Second, if you're testing the circuit and not just the main, I would assume there was still something connected to ground causing that reading. If the flutter is hapoening like clockwork then something with an electronic circuit is causing it: Look for power metering
They usually just swing somewhere in the neighborhood of what the actual reading is.A flutter to zero or a flutter to infinity?
Your CTs are fullt insulated for the bus voltage, they should not cause a problem.By "power metering" I assume you're speaking of CTs clamped around the conductors, no direct connection right?
