    Whole-house surge protectors

    Posted previously: Your building must have an earth ground that both meets and exceeds post 1990 National Electrical code. Not just meet. For example a breaker box is connected to an earth ground rod via a quarter inch bare copper wire. That wire goes up over the foundation and down to an...

    Whole-house surge protectors

    You had no properly earthed 'whole house' protector. So the surge - a direct strike - did damage that never happens in any facility with proper earthing and 'whole house' protectors. You had what kind of protectors? Plug-in protectors can sometimes make damage to electronics easier...

    Whole-house surge protectors

    Most of us are only educated by retail propaganda. Most believe only what they are ordered to believe, do not always demand numbers, and never ask for the always required "reasons why". It is why my father so enjoyed advertising. Lying and manipulating such people was fun. Either one...

    Whole-house surge protectors

    If your protector explodes, then it was grossly undersized. Ineffective protection. Exploding protectors are, for example, power strip protectors that do not even claim to provide that protection. Are often intentionally undersized to explode (because that promotes sales) and to increase...

    Whole-house surge protectors

    The OP is not asking about temporary power. Outages obviously are not hardware damage. The OP is asking about hardware protection. Why does a direct lightning strike cause a temporary power outage? Reclosures reconnect power after a few seconds. No hardware damage even to utility...

    Whole-house surge protectors

    [QUOTE=rockcrawler;5612625]There isn't any surge protector that will protect against a "direct lightning strike". Lightnings have enough power to reach the ground from the sky through air, so some pissy surge protector won't do a thing. Neither will open switch contacts, it will jump those too...

    Whole-house surge protectors

    [ They sell in Lowes and Home Depot for less than $50. The most minimal 'whole house' protector must be 50,000 amps because direct lightning strikes are typically 20,000 amps. No complaints after two years? Typically destructive surges occur maybe once every seven years. No protector...
