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.
CAUTION:
GFCI outlets do not protect sensitive
electronic equipment such as laptops
from voltage surge. Plug sensitive
electronic equipment into a separate
surge protection device.
DC Branch Fuses
The 12 Volt DC fuses are the 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
electrical system.
The 12 Volt DC fuses service the interior
house lighting, ventilation fans, furnace
and monitor panel. Fuses are color coded to
indicate the rated amperage. 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 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 turned off.
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, as
in the case of 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.
