The electrical system in your motorhome is designed and built in accordance with the
latest codes, standards, and regulations effective at the time of construction. It consists
of two types of systems, alternating current (AC) 120 Volt service and direct current
(DC) 12 Volt service. Because of the many model variations and options, it is not
possible to provide wiring diagrams in this manual. We recommend that any electrical
work be done by a Thor Motor Coach dealer or a qualified RV electrician.
Note:
The electrical system is engineered and tested for safety.
Circuit breakers and fuses protect the electrical circuits
from overloading. If you plan to make modifications or additions
to the electrical system, Thor Motor Coach strongly
recommends consulting a certified electrician for assistance to
ensure continued integrity and safety of the electrical systems.
Please note that any modifications may void the
Limited Warranty.
The electrical power supply provided for the motorhome is a dual system, operating
with 120/240 volt AC and or 12 Volt DC. The 120 Volt power may be provided by
either connecting the motorhome to an outside power source when parked, or by
use of a motorhome generator. When the 120 Volt system is operational, power also
passes through a system converter, allowing the full use of all 12 Volt functions in the
motorhome.
120 Volt appliances in the motorhome include the refrigerator, ice maker, roof mounted
air conditioner(s), TVs, DVD player, microwave oven, converter and the water heater.
The refrigerator also has the option of running on propane gas when 120 Volt power is
not available. All other electrical functions in the motorhome are supplied with 12 Volt
power.
When it is not possible to access 120 volt power, the 12 Volt system functions can
be supplied by the auxiliary batteries. The chassis battery is protected by a battery
isolator controller to prevent discharge from excessive electrical consumption when
the motorhome is not running. The auxiliary batteries are recharged by the power
converter when the motorhome is attached to an outside 120 volt power source, or
by the generator when it is running, and by the chassis alternator when the chassis
engine is running.
Note:
These three shore power outlets are most commonly used
throughout the United States.
CONNECTING THE SHORE CORD TO A NON-GROUNDED

IMPROPERLY
CAN RESULT IN DANGEROUS AND POSSIBLY FATAL
ELECTRIC SHOCK. Due to the potential danger in failing
to heed this warning, the motorhome manufacturer
cannot be responsible should damage, injury, or death
result from failure to connect the power cord to a properly
grounded power source.
