TIFFIN MOTORHOMES –ALLEGRO® Chapter 7 ELECTRICAL FEATURES
General Information
There are two electrical systems in your Allegro motor home—these are the 12-volt DC (VDC) system and the
120-volt AC (VAC) system. Most standard appliances require the 120-VAC system, while the majority of the
lighting systems used in the Allegro use the 12-VDC system. The electrical power for the 12 VDC system is
supplied by the batteries of the Allegro; those batteries are, in turn, charged by a power converter.
The electrical power for the 120 VAC is supplied either by the power cord when the Allegro is connected to an
external power source or when the on-board electrical generator is in operation.

Caution
Failure to turn off the 120 VAC appliances when starting or stopping the generator
may damage the transfer switch and/or electrical appliances.
To connect the Allegro to an external source of 120 VAC electrical power, it is first recommended that all of the circuit
breakers are in the “off” position—this is done to prevent any power surge upon connecting the motor home to the
external power source. Then unwind the power cord from the electrical compartment located in the compartment
behind the driver’s-side rear tires. The flexible, power cord supplied with the Allegro is designed to handle up to
either 30 or 50 amperes, depending on the configuration ordered.
Make sure that the pins in the male end of the plug are oriented correctly so that they match the power cable, and that
they are in good condition (i.e., aren’t bent or damaged). If there is a circuit breaker switch at the “plug” end of the
power cord, that breaker should be turned “off” before making the connection. Insert the plug into the mating outlet
and then turn the circuit breaker “on.” Close and lock the electrical compartment door to protect the contents and to
keep them clean and dry. Close the cover on the power box, if so equipped, to avoid an unintentional disconnection
and to keep the contents clean and dry. Then switch the main breaker to the “on” position. When properly connected,
the 120 VAC system provides power to all the 120 VAC circuits and outlets when the main breaker is turned “on.”
Circuit-Breaker Boxes
For the Allegro, the 120 VAC and 12 VDC breaker boxes (Figure 7-
1) are typically located beneath the refrigerator or in the bedroom
[
if inside the vehicle
] or in the storage box [
if outside the vehicle
].
The circuit breakers and associated fuses are installed to protect the
electrical system of the Allegro from any overloads. Do not attempt
to change the electrical circuitry or to add appliances yourself.
Please consult an authorized Tiffin Motorhomes Dealership or Tiffin Motorhomes, Incorporated in Red Bay, AL to
determine whether any changes you desire are appropriate and acceptable. Tiffin Motorhomes’ qualified staff of
electricians can readily determine whether any changes sought (e.g., CB radio, amateur radio, satellite television
receiver, personal computer system, and the like) are possible or not and can advise you on how best to realize these
enhancements.
