Distribution Panel - House 12 Volt; Fuses - Holiday Navigator 2003 Owner's Manual

The 12 Volt DC house distribution panel
contains fuses (located in the bedroom) that
protect the electrical circuits. These fuses are a
standard automotive type.
When a fuse is "blown," the wire in middle
of the plastic case will be burnt. A broken, bad
or "blown" fuse must be replaced with a fuse of
the same rating and type. Using a fuse with a
different rating or type will defeat the circuit
protection provided by that fuse and could result
in damage to the motorhome's electrical system.
The 12 Volt fuses, located in this distribution panel, service
the interior house lighting, ventilation fans, monitor panel,
furnace and water heater. Should a fuse blow it will be
evident by the broken metal strip located in the center of the
fuse. Replacement fuses should be of the same amperage. If a
higher rated fuse is installed it can damage the wiring. Fuse
current set points follow much of the same electrical principle
as the 120 Volt AC breakers. Using 12 Volt DC as the
electromotive force can make it more susceptible to outside
influences, such as corrosion from weathering or oxidation.
The large variety of applications this voltage can be used
in makes it a diet staple for most of the recreational vehicle
and automotive industries. The danger from shocks with this
voltage is minimized, but can still occur. A good example is
when a magnetic field is generated, then collapses when the
power supply is cut. The result is a discharge that can reach
tens of thousands of volts for a short time period. Care should
be used when working with this voltage as current values can
be quite high, like in the case of a battery cables.
Shorting a battery cable to ground with a battery at a
reasonable state of charge can result in a fire or serious
personal injury from a burn.
