Sorry I come from the criminal colonies were the British taught us to
speak. I think it comes from the original DC power grid where you got
one wire in and 6 foot steel rod driven into the earth out the back. I
can't get my head around the whole AC wiring thing of active and
neutral. If you touch either it give you a shock, can't see what's so
neutral about it.
