This is not intended to create a flame war.
I am deeply concerned about the blatant misinformation being written by a small group of wRECkers. There is nothing more dangerous than bad electrical advice. Many here have genuine questions which should only be answered by qualified people. Many answers are the right ones. A few are downright wrong and dangerous.
How does the uninitiated know the difference?
That's right... they don't.
That makes it a double-dangerous situation:
A) The person with the question doesn't have a clue otherwise the question wouldn't be asked in here. B) That person who then gets an answer doesn't have a clue on the accuracy of such a reply running the risk of burning down the house with the cat in it, or blowing off a finger, doing irreparable damage to an expensive motor, or worse, causing death.
ALL of those things are bad.
