Can a Surge Travel on a Residential House's Wiring that is higher than 6kV and 3kA?
If this is so, how does a surge from direct or indirect lightning travel through home wiring and literally blow up electrical equipment?


I don't think that is true, but it doesn't matter.  It doesn't take 30A, let alone 3000A to blow up most home electrical equipment.  Lots of surges will have high enough to burn up electronics on the circuit but be far too small to vaporize the wiring.
