A value of insulation resistance slightly below the recommended approximate value does not necessarily indicate that immediate repair is required. What course of action should be taken by an electrician in this situation?

What will be an ideal response?


The electrician should take a series of readings at weekly intervals to detect any progressive decrease or sudden drop in the insulation resistance. If the resistance continues to decrease, then the fault is to be located without delay. A slightly low but constant value of resistance should not cause concern.
