You may at some time experience an electrical shock when
entering or exiting your RV. This is often caused by the
wiring in the electrical receptacle that your RV is plugged
into or an improperly wired extension cord. If the "hot" and
"neutral" wires are reversed, your coach and you may become
an electrical circuit with unpleasant or dangerous results.
There is a small polarity checker available that will
eliminate the guesswork and the hazards before you plug
in your electrical cord. Everyone should have one of these
as standard equipment!
