GFCI Outlet
For safety, outlets located near water sources (inside or outside) must be protected with a Ground Fault
Outlet. This is usually located in the bathroom and can be identified by the test and reset buttons in the
center of the outlet. If the GFCI circuitry detects a difference between the power flowing through the
hot wire and the power flowing back through the neutral wire, it assumes that the leaking current is
flowing through a human being and cuts power in a few milliseconds to protect you from injury.
If you ever have an outlet that is not working, the GFCI is the first thing to check. Press the reset button
to try and restore power to the downstream outlet.
All outside outlets are downstream from (fed by) a GFCI outlet.
Surge Protection & Electrical Management Systems
Electrical Management Systems (EMS) protect against a number of common electrical problems
including high voltage, low voltage, open neutral, incorrect frequency, and reversed polarity. Of these,
low voltage is probably the most common problem RVs are likely to experience. In the summer, when
every RV turns on one or more air conditioning units, campground power can be overwhelmed, and
voltage can drop as a result. Wiring and equipment problems, especially in older parks, can also result in
low voltage. Some of your devices can be damaged by low voltage.
An open or partially open neutral line from the power pedestal can wreak havoc on your coach’s
electrical devices resulting in thousands of dollars of damage.
