#6 copper or #4 aluminum to the ground rod? I've never seen that #4 AL can be legal in my 30+ years in the industry. Sounds like some know-it-all has found a few tables in the code book for AL/Cu ratings and feels that they apply across the board.
That's the most MINOR bad information that I saw given.
Wow, that entire post is an accident (and subsequent lawsuit) waiting to happen. I sure hope that someone figures out a way to squelch it before something really bad happens.
