Distribution Panel; House.12.Volt.dc; Automatic Reset Circuit Breaker; Fuses & Circuit Breakers - 12 Volt Dc - Holiday Rambler Owner's Manual

Electrical shocks resulting from ground
faults can be felt, but such a shock is
considerably less than one without ground
fault protection. People with medical
conditions that make them susceptible to
shock can still be seriously injured. A GFCI
outlet or breaker will not protect against shock
from a normal current flow. For example: a
shock from touching both metal prongs of an
electrical cord or appliance while plugging it
in.
WARNING
If a breaker or outlet continually trips,
DO NOT continue to reset breaker
or outlet until the problem has been
identified and corrected.
NOTE
The ground fault outlet or breaker
should be tested once a month to
ensure it is operating. Use the TEST
button on the outlet or breaker. It
should trip with an audible "click."
The breaker or outlet will not trip if
AC power is not present at the device.
If power is present and the device will
not trip, replace it before using that
circuit.

House 12 Volt DC
The 12 Volt DC distribution panel contains
fuses that protect the interior house electrical
circuits. The DC distribution panel is located
in the bedroom or bathroom area. These fuses
are a standard automotive type.
A representation of distribution fuse panel. Actual panel
will vary with options and changes to the motorhome.

AUTOMATIc REsET cIRcUIT BREAkER

Located in the battery compartment is a
black box that contains various automatic reset
circuit breakers. An automatic reset circuit
breaker automatically resets after opening
(tripped). If the fault still exists, the circuit
breaker will continue to recycle between
On and Off until
the overload is
corrected.

Circuit protection devices are installed to
protect circuit wiring in case an over-current
condition occurs. An over-current condition
usually falls into one of two categories: a short
circuit or overload. A short circuit is when a
break or fault in the circuit allows electricity
to flow directly to ground. Circuit overload is
when circuit amperage or the electrical load
exceeds designed operating parameters.
Several factors are considered when
designing a circuit to operate an electrical
load. The amperage required to operate the
electrical load will determine wire size and
wire insulation type. The application of the
electrical load can determine whether a fuse or
060165t
circuit breaker is selected.
Circuit protection devices come in a variety
of shapes and ratings. Most common are the
blade style plug in fuse and auto reset circuit
breakers. These types of circuit protection
devices are readily available from auto supply
stores. Circuit protection devices in a 12 Volt
DC system are actually rated at 32 Volts DC
due to voltage variances in a 12 Volt DC
system. Replacement devices must use the
same amperage rating and be of the same type
as the original for proper circuit protection and
electrical safety.
Generally a fault exists in the circuit
when an over-current condition has caused
a fuse to blow or circuit breaker to trip.
Until the condition that caused the fault
is corrected, replacing the fuse may be a
temporary fix. Continually replacing the fuse
or circumventing the protection device can
jeopardize safety and circuit integrity.
