What it ACTUALLY means is that they must be within 6' of an opening, and cannot be spaced more than TWELVE feet apart. Why don't they just SAY that?
They can't just say that, because it woould be too simple. There would be a lot of code consultants,etc out of work. Many more homeowners would be doing there own work. As it is now, most shouldn't be doing their own work.
I was in a local home improvement store similar to Lowes / Home Depot.
Husband and wife walk past a rack of how-to electrical books.
Wife asks: "Do you need a book to tell you how to wire?
Husband replies: "No, I know all about wiring"
They walk past the 19 cent blue plastic outlet boxes, wife asks: " Do you need some of these boxes"?
Husband replies: "No, I know what I'm doing, I've got electric tape".
I love the wording for outlet spacing in the code quote. I have one general contractor who wants outlets 8' apart, because he thinks he is cheating the government ("National" Electric Code), and saving money because it uses 1/3 less outlets.
