A customer of mine had squirrels tear up some NM cables in his attic. I suggested a thorough inspection be done (visual) by coming back and clearing insulation to see all cables and also perform a cable insulation test. Anything I'm missing?
I'm also wondering if the megger would read a cable like the one pictured as being good if nothing is close enough to arc or jump/read across. .
