The application of the electrical
load can determine whether a
fuse or 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
overcurrent 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 x.
Continually replacing the fuse
or circumventing the protection
device can jeopardize safety and
circuit integrity.
WARNING:
Replacement fuses or
circuit breakers must be of
the same type and rating
as the original equipment.
Installing protection
devices other than the
original type and rating
will create a safety hazard
that will potentially result
in circuit and/or component
damage and fire.
Fuses:
Blade fuses comes in three sizes:
Mini, Standard and Maxi. Fuse
color determines amperage ratings.
A blown fuse indicates an over-
current condition has occurred.
Typically the conductor strip in the
center of the fuse is broken, but
not always, and is best veried by
use of a 12 Volt DC test light. Two
exposed terminals are located atop
the blade fuse housing. The fuse is
good if the test light illuminates at
both terminals. This may require
the circuit be activated for power
to be present at the fuse. The fuse
is bad if the test light illuminates at
only one terminal.
There are three types of
Circuit Breakers:
Type 1 is an automatic reset
type circuit breaker. This type of
breaker may cause component
damage under a short circuit
condition. It will not damage the
circuit, the installation or present a
safety risk
Type 2 is an automatic reset
type circuit breaker. Under a short
circuit condition, this type of
breaker will not cause component
damage or damage to the circuit,
the installation or present a safety
risk.
Type 3 is a manual reset
circuit breaker. This type of
breaker will open under a short
circuit condition and must be
manually reset.
