12-Volt DC (VDC) Receptacles
Your Allegro Motor Home may be equipped with a 12 VDC receptacle conveniently
located inside of the center console (Figure 7-6, black receptacle, bottom half of the
picture). This 12 VDC receptacle can be used for providing power to various items, such
as cellular phones, personal computers, or portable communications equipment.
This receptacle is usually found on the bulkhead in front of the passenger's seat so that it
is conveniently available to be used by the personnel in the cockpit area This receptacle
accommodates the "cigarette-lighter" type of connector.
Ground-Fault-Circuit-Interrupt (GFCI) Receptacles
In the kitchen and bath areas, there are 120 VAC GFCI receptacles (Figure 7-7) which provide
greater protection against inadvertent electrical shocks. These specialized GFCI receptacles
provide both overload and short-circuit protection for the user. The electrical receptacles located
in the slide-out are wired through the kitchen GFCI. The exterior receptacles are wired through
the bathroom GFCI. Consequently, if an appliance plugged into a slide-out or
exterior receptacle is not working, check for a tripped GFCI in the kitchen or bathroom.
All GFCI-protected receptacles are marked as such, but only one of them may have two
pushbuttons on the receptacle (as shown in the picture). The upper pushbutton is a "test" button
which can be used to assure that the GFCI function is working—all one need do to test this

disconnected (i.e., no power is available at the GFCI-protected receptacles).
To reset this GFCI breaker, push the lower button (the "reset" button) to restore power to all the
GDCI receptacles on this circuit.
In addition, these receptacles protect the user from ground faults between an electrically "hot" wire and ground. The
GFCI will not reduce the shock hazard if the short is between a neutral and "hot" wire, or two "hot-load" wires.
The GFCI should be tested at least once a month. The 120 VAC electrical system must be "on" for the GFCI
to be tested. To test the GFCI the reset button needs to be pushed in fully before starting the test. Push the
test button; this will cause the reset button to pop out which means that the protected circuits have been
disconnected. Push the reset button back in until a "click" is heard—this will re-activate the protected circuit.
If the GFCI is working properly, the reset button will remain in the "in" position.
