ALCULATING LECTRICAL
The relationship between amps and total
wattage can be misunderstood. You may
think there is a proportionate link between
differing amp levels when, in fact, that isn't
necessarily so.
For example, 20-amp service requires 2,400
watts (20 amps times 120 watts), and 30 amp
service needs 1-1/2 times as much power
(3,600 watts, or 30 amps times 120 watts).
However, for 50-amp service the potential
amount of power used – 12,000 watts, or 50-
amps times 240 volts – represents more than
three times as much possible demand as 30
amp service. Conversely, a RV rated for 50-
amps (incorrectly) hooked up to a 30 amp
outlet is only getting about one-third of the
power that the RV may need to run a full
complement of appliances.
As you purchase and use 120-volt appliances,
remember your RV is limited to a maximum

load

of 50-amps.
traveling, remember each appliance and 120-
volt accessory places a load on the RV
electrical system.
You can determine the amperage rating of an
appliance by dividing the watts used (usually
found on a label or plate affixed to the
appliance) by your RV's supply voltage. For
example: 1200-watts divided by 120-volts AC
equals 10-amps.
In addition, remember many RV appliances
require more amps to start the appliance than
to run the same appliance. For example, a
roof air conditioner can draw approximately
16 amps to start, but may only use
approximately 13 amps once it is running.
You may periodically trip circuit breakers if the
combined load of your appliances and
accessories exceeds your 50-amp rating. To
remedy, turn off the appliances until you are
at or under the 50-amp load rating, and then
reset the circuit breaker.

ENERATOR
The factory-installed generator (also referred
to as a genset) will produce 120 VAC power
for use when camping in areas where shore
power is unavailable. 120-volt power from the
generator is outputted to the AC distribution
center by way of a factory-installed automatic
transfer switch. In the default mode, the
automatic transfer
generator to the AC distribution center when
the generator is operating and shore power is
disconnected from the RV. The power to start
the generator comes from the auxiliary
battery. A remote start/stop switch is located
on the generator.
Exhaust gas fumes
Be aware the generator runs on gasoline and
gives off carbon monoxide. Avoid inhaling
exhaust gases as they contain carbon
monoxide, which is a potentially toxic gas that
is colorless and odorless.
1. Do not run an engine (i.e., tow vehicle
engine, generator engine, etc.) in a
confined area, such as a closed garage,
any longer than needed to move your RV
in or out of that area.
2. The RV windows should be closed while
driving or running the generator to help
avoid drawing dangerous exhaust gases
into the RV.
3. If you suspect that exhaust fumes are
entering the RV,
determined and corrected as soon as
possible.
The best protection against carbon monoxide
entry into the RV is a properly maintained
ventilation system and an active CO alarm. To
allow for proper operation of the ventilation
system, keep the ventilation inlet grill(s) clear
