  • Good Job. There are many people here that doesn't have knowledge about electricity and standards and writes a lot of bullshit...

  • You NEVER want lightning strike energy entering the attic!!!
    .......
    And you NEVER attach a lightning conductor to highly flammable kiln dried lumber!!!!
    ......
    This type of installation is BEGGING for a fire!!!!

  • They say lightning rods don’t attract lightening and it’s an old myth but if these rods don’t attract lightening then how are they expected to always work? What’s the guarantee that lightening will hit a rod in a specific place on the roof and not the rood in between the rods if they don’t attract? Logic dictates that for this system to always work, it must attract lightening to eliminate randomness of the strikes on the roof.

  • By 0:20 you already know it won’t protect you from lightening surges that come through telephone poles or power lines cause those rods only provide a path for the lightening from the sky via the rods. Not via power lines or cables like telephone cables for example. Hence this video’s Flag ship device is only one part of total house protection

  • The rods charge the passing rain clouds to prevent a strike , believe it or not .

  • Hello could you explain me about how we calculate conductor size for lightning ?

  • How would someone protect their tiny house (that rests on a metal trailer) from a lightning strike?

  • ive been a lightning conductor engineer for nearly 40 years and have to say, that system is a total pile of dangerous crap
