    Requires a rubber glove.
    May damage the test set.
    May damage the insulation under test.
    Is not necessary

    I saw this question and answered "Will ensure immediate personally safety." I didn't see it show up in my wrong answers.

    The hipot test is a nondestructive test that determines the adequacy of electrical insulation for the normally occurring over voltage transient. This is a high-voltage test that is applied to all devices for a specific time in order to ensure that the insulation is not marginal.

    Hipot tests are helpful in finding nicked or crushed insulation, stray wire strands or braided shielding, conductive or corrosive contaminants around the conductors, terminal spacing problems, and tolerance errors in cables. Inadequate creepage and clearance distances introduced during the manufacturing process.

    This is a bit misleading, I would say a hipot can be a destructive test.

    Agreed. For instance, A VLF hi-pot test is less destructive, but can still damage a cable if there is a pre-existing condition. A DC hi-pot test is a destructive test for cables, not only in bringing out a fault in a cable but also the adding stress on the cable itself.
