There will always be some small current flowing during a hipot test.
If there isn't any current flowing, it's probably because you're circuit
is open somewhere (probably the test jig, or the hipot tester's leads).
To prevent this problem from going undetected some manufacturers
began to

This is a good question. Unfortunately, it's very difficult to answer.

I don't think GFIs are failsafe. Don't they all come with test buttons?

Why has no one mentioned using a GFI detector as a failsafe way to make
certain the installation is done per spec?
After all, in the US the manufacturer still comes out liable for any
damages.

Try this loophole on for size.
Depending upon the installation location - it may be necessary (required by
law) to perform an earth bond test after installation of the equipment. In
such a case, testing at your production site would not guarantee a higher
