I have switches for all my wall outlets. I switch them off when not using the systems. Isnt that safe?
When you're talking about the really high voltage power surges that might result from a lightning strike to the power grid that supplies your home turning off normal wall switches might not be good enough. That kind of currenr is strong enough to jump the small gap in a wall switch.
In some circumstances nothing short of unplugging your gear will protect it, but a whole house surge protector (when properly installed where the power enters your home) that shunts the power surge directly to ground before it gets into your house wiring is your next best solution.
Thanks. We have lightning arrester on the roof. I also have surge protector for the stereo system, fridge, AC units and computer. These have saved us from the severe current fluctuations we have regularly. Also have circuit breaker at the main board. I unplug the music system at night and when there is likelihood of thunderstorms.
There is a curse that some people use around these parts, 'let the lightening strike'.
I hope nobody has cursed me yet!
See my post below. Light switch was off. Lightening blew it apart and jumped the contacts to go down stream to wreak havoc.
