Hi, sorry I didn't get notification of your comment until now. If you are performing an insulation resistance test of the circuit, it doesn't matter which terminal you connect the megger to, you should get the same result.

@@davidrainey3326 Cool, thanks for the reply! One probe connected to either end's conductor and the other probe connected to ground to Earth. Or does the second probe get connected to something else?

@@PeteLehmann Yes, that's correct, always connect the red + probe to the circuit under test and the black - probe to a good earth ground. When actually troubleshooting a low resistance ground fault or short to ground on a circuit it is best to switch from a megger to an analog volt-ohm meter such as a Simpson 260 as they are better for measuring low resistances. But always maintain the proper polarity or you can get a false reading. I know that sounds weird, but it's true.
