Maintenance
Inspect the power cord for cuts, cracks and worn insulation. Have the power cord
replaced immediately if these symptoms are noticed.

When connecting appliances to the electrical system, remember that 120-volt
power usage is limited to a total of 30 amps (for 30 AMP systems) and 50 amps
per electrical system leg, for a total of 100 amps (for 50 AMP systems) . Be
mindful of the fact that each operating appliance collectively places an added load
on your 120-volt electrical system.
An unintentional “trip” of a circuit breaker may occur if you overload the motor
home and/or campground electrical system. The amperage rating of individual
appliances can be calculated by dividing appliance wattage consumed (normally
listed on the appliance) by nominal design voltage (120 for a 120-volt appliance).
For example: 1200 watts divided by 120-volts equals 10 amps
.

Only connect the shore power cord to properly wired power receptacles.
30 amp systems : 30 amp NEMA TT30 120-volt
50 amp systems : 50 amp NEMA 14-50 120 volt.

Do not connect the shore power cord to any power receptacle until you have
contacted the campground owner and/or premise attendant to verify proper
shore receptacle polarity and grounding. Polarity indicators can be purchased
in most electrical and hardware stores.

Do not use a cheater plug, adapter or extension cord to reconfigure incoming
AC power or to break the continuity of the power cord grounding circuit.

Do not connect the power cord to an extension cord. Use of an extension
cord can cause overheating of the extension cord and can create a low
voltage condition. Premature failure of connected 120-volt AC powered
equipment may result.

Do not connect the power cord to an outlet that is not grounded or adapt the
power cord plug to connect to a receptacle for which it is not designed.

Do not remove the power cord grounding terminal to allow connection with a
non-grounded receptacle. Disabling the grounding circuit of the shore power
cord may create a shock or electrocution hazard.
It is the responsibility of the owner to ensure that the electrical receptacle being
used is properly wired and grounded.
Reverse polarity and/or improper grounding of the motor home can cause property
damage, personal injury or death. Failures due to improperly wired and grounded
electric receptacles are not covered by the limited warranty.
WARNING
To help prevent power surges from damaging the electrical system and its
connected devices, please follow the instructions listing below when
connecting to shore power.
