few days ago I ran into a Ham on 40m who is a licensed electrician
here in California. so I took the opportunity to ask him why 240v
appliances like ovens, dryers and water heaters need a ground wire.
His answer: To protect people from being shocked by the Neutral wire.
Obviously he is wrong. The ground wire (or bond as we call it) is to bond
all electrical non current carrying metal back top the electrical panel so
that if a current carrying wire contacts metal it will trip the breaker and
therefore someone will not be shocked.
