After some time away..............came home to:

two TV's
two DVD / VCR combos
wireless router
garage door opener
forced air furnace
GFI in garage tripped & will not reset
some wall repectales & lighting circuits not working
(but no breakers tripped and power ok on both hot legs)

all items were non-functional, non- responsive, no power up

cable company had called & said their cable equipment in the vicinity
of our house was "blown"

I pulled the panel cover & tightened all wire clamps on the breakers
and the screws on the neutral bus....found a couple slightly loose.
All circuits returned to working order.

furnace 24v transformer bad...replaced it and furnace now working
bought new router before I checked to see if old router failure was
just power supply, it was

no lightning storms while away

any ideas as to cause of destruction of all these electronic items?

voltage surge? cause of said surge?

cheers
Bob
