be faulty insulation, wet wiring from inside an appliance or any device or
equipment plugged in or wired to that circuit. The “ground fault” portion of the
outlet or breaker uses sensitive electronics inside the outlet or breaker to detect
a ground fault problem. The way it works is the electronics monitor the normal
current flow, which we think of as the power flowing to the “hot” or black wire
through the load (eg. a light bulb or an appliance) and coming back on the
“neutral” or white wire. If just a small amount of the current comes back on
the safety ground wire, the electronics will “trip” the breaker or outlet and stop
the flow of electricity. The amount of current it takes to trip the device from a
ground fault varies slightly from the different outlet or breaker manufacturers
(approximately 30 mils or less). Electrical shocks resulting from ground faults
can be felt, but such a shock is considerably reduced compared to one without
the ground fault protection. People with heart conditions or other conditions
that make them susceptible to shocks can still be seriously injured. A GFCI
outlet or breaker will not protect you against normal current flow. An example
of this would be if a person touched both metal prongs of an extension cord or
appliance while plugging it in.
WARNING: If a breaker or outlet trips continually DO NOT
continue to reset breaker or outlet until the problem has been
identified and corrected.
NOTE: The ground fault outlet or breaker should be tested
once a month to insure it is working properly. Use the “TEST”
button on the outlet or breaker. It should trip with an audible
“click”. The breaker or outlet will not trip if no AC power is
present to the device. If power is present and the device will
not “trip,” replace it before using that circuit.
NOTE: One mil is equal to 1/1000 of one amp.

A majority of the lighting and appliances are designed to operate from
12 Volt DC (direct current) power. This is why the batteries play such an
important role in the function of the motorhome. There are exceptions with
appliances such as the microwave or television; however, indirectly they still
operate from 12 Volt DC power, as they can be operated from the inverter. The
chassis functions (engine, transmission, dash air, etc.) are also 12 Volt DC.
With the all technological advancements taking place in the past several
years, manufacturers have now incorporated electronics into these systems. It
is important to keep the 12 Volt system(s) in good working order. These
systems, with their incorporated electronics, are voltage sensitive. Some items
can be damaged if the DC voltage is not maintained within the designed
specifications.
