One of the testguy questions was this,
When performing medium-voltage cable sheath testing, the test voltage is connected in such a way that the ____ potential is connected to the shield, and the _____ will be connected to earth.
a. negative, positive
b. positive, negative
c. any of these
It said the correct answer was “negative, positive”. Is this correct? Everything I found online said it should be “positive, negative”. I even asked ChatGPT, and it said to connect the positive wire to the shield.
