Rodent Cable Damage

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. .

I've seen wire like that which would megger fine but was very dangerous if it was missed on a visual inspection, and the mouse/rodent landed on the energized wire.

Somehow the rodents gnaw energized romex all the time but very few are killed.

I've had some pictures of squirrels and gnawed romex at a state fair exhibit and one ole gal chewed my butt for giving them a bad rap:laughing:
