I believe the wire is rated at around 600V.

The question is what Voltage should I set the Hi Pot tester to and why. The
other end of the Hi Pot tester will connect to the conduit.

Thanks


Typical control cable is 600V. When we used to test the cabling for new
control circuits (I was with a large electrical utility), we always
tested them at 1000VDC. Usually resistance testers ('Meggers') are DC
and 600VAC is pretty close to 1000V peak, so that was our logic.
Certainly a 600V control cable should accept 500VDC and still show
several Megohms, even if it is very old and in in a poor environment.
New cable would be 200+.
