How little or how much assessing to a residential wiring system should be conducted after a hit?
I did one yesterday and found..

Fried TV, Computer, Microwave.
No ground rod.
Water meter not jumpered.

I installed a rod and jumpered the meter.
It had been a couple weeks since the hit and she said that everything else was operating OK.
I explained the megger test but informed her that if everything was not disconnected, the test would provide questionable results. Also, if everything was disconnected, and unsatisfactory, or marginal readings were observed it could be extremely difficult and costly to locate the problem.
She is going to think about it .

Anyone else have any ideas?
