1) Copy following link for live answer Dec 2012 to figure correct wire sizehttp://waterheatertimer.org/Color-codewire.html
2) Fixya posts 'recommended' answers based on computer guessing what you asked. Look for date on each answer.
Recommended answers can be totally unrelated, but sometimes they are spot on. These answers were posted by experts over previous years, and now fixya owns the work done by others and uses that work to answer questions that live expert does not answer.
3) This particular Question was posted under 'Chrome timer knob set,' and somehow ended up among timer questions. Each expert answers questions by expertise such as timer, water heater, electric wiring etc.
Often the questions do nor show a product or clearly state what answer is needed. People do not always know what they are asking for. That's why fixya is here: to help sort out possible answers.
So the expert sometimes guesses at answer, or the computer guesses which recommended answers to post.
