Can a "megger" or insulation tester be used to test for insulation integrity, ground faults, and short circuits, for residential wiring?
Branch circuits and feeder conductors are exposed where they terminate. How can an insulation tester, "megger", test for insulation integrity if the insulation is removed from the conductors where they terminate?
If insulation testers can be properly used for residential wiring, it seems to me a great way to check the integrity of the branch circuits before sheet rocking. It can also be used for troubleshooting.
