    Kimrichi, We don't have the book you are studying from. Can you ask the question word for word from the book? This is Mike Holt's forum but most won't have that book. I have some for the 2005 but it's probably different.
    Also check Mike Holt's website as he has a link to corrections for mistakes found in the books.
    If you aim at nothing, you will hit it every time!

    You can have a 3Ø, 3 wire service or a 3Ø, 4 wire service.

    Not nice... The OP probably doesn't speak English very well and based by their name they are probably Korean. Imagine trying to learn something as complex as electricity using a resource written in a foreign language.
