SECTION 6 - 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
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.

Only connect the shore power cord to properly wired 30 amp NEMA TT30 120
volt power receptacles.

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
30 amp 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.
