    Is it recommended for my new TV and sound system, or just another rippoff.?

    Until the first electrical storm, or the power company has a transformer go
    arse-up.
     
  4. Simply switch the whole lot off at the wall, you'll save a bunch of
    standby power too.
    Surge Protector isn't a bad idea though, but like audio cable, you can
    pay ridiculous amounts of money for marking fluff that gives you zero
    extra benefit.
    A cheap surge protector power board from Bunnings or wherever will do
    the job, don't buy one from the shop.

    A surge protector is not enough for a *direct* strike (which is very rare
    indeed) but it is useful for nearby strikes and general static buildup,
    which are infinitely more common. So yes, worthwhile. Quite different to
    monster OFC speaker cables and similar snake oil!

    And one more thing. Switching off at the wall is useless. Unplug completely
    from aerial and mains (but not when the storm is already on you!)

    The models I have are afordable and come with an insurance , certainly
    wont do any harm .

  9. *useless*??
    It's certainly better than having a direct copper connection when the
    appliance is switched on.

    Yes, unplugging is better if you are that paranoid, and happen to be
    home at the time.

    Well, I certainly won't be buying anything from rage audio. The website link
    is engineered with similar care...

    Yes, useless. The tiny air gap left when a GPO switch is opened is quite
    useless for the near end results of a spark many hundreds of metres long.
    Agree about the "if you are at home" bit though. In high risk areas (eg
    Florida) many computer users routinely unplug when going out.
     
  12. Direct copper connection is *worse* than having an extra air gap in
    series by having the switch turned off.
    That does not mean your device cannot still get zapped with the switch
    off, but having the switch off is *better* than having it on.

    You appear to be interfering with yourself bwian
    perhaps stopping would be good.

    You would probably be better served by checking that your insurance covers
    damage caused by "fusion".

    Absolute rubbish! Fusion is defined as the burning out of the windings of an
    electric motor and has nothing whatsoever to do with lightning.
     
  19. Sally

    Sally Guest

    Yes. Direct copper connection is obviously worse, and so switching off does
    improve protection. But the GPO air gap (typically 1-2 mm) for 240V is still
    far too small for a direct lightning strike (already perhaps 5 km).
     
  20. Of course, and that's all I was saying, glad you agree.
    The thread is about "surge protection" in general, not just lightning
    strikes.

    Dave.
