A Ground Fault
is a outlet that shuts off an electric power circuit
when it detects that current is flowing along an
unintended path, such as through water or a person.
GFCI outlets are usually located in areas where
water can possibly come into contact with the person
using the outlet such as in bathrooms, kitchens, or
Usually, a small button is located in the middle of
the outlet for resetting the outlet. When a GFCI is
triggered the outlet will no longer get power. Many
times GFCI outlets will be connected from one
bathroom to the next so that if one goes out, you
have to go to the next bathroom to hit the reset
A GFCI works by measuring the current leaving one
side of a power source, and comparing it to current
returning on the other. If they are not equal, then
some of the current must be leaking in an unwanted
way, and the GFCI shuts the power off.
You can test the GFCI any time by hitting the reset
button off and on. GFCI's can also be installed in
circuit breakers in your electrical panel.
Arc Fault Circuit Interrupters
(AFCI) help prevent electric
fires. An AFCI distinguishes between a
harmless arc that occurs incidental to
normal operation of switches, plugs, and
brushed motors, and an undesirable arc that
can occur, for example, in a lamp cord which
has a broken conductor.
AFCI breakers have been required for
circuits feeding electrical outlets in
bedrooms of homes by the electrical codes
of Canada and the United States since the
beginning of the 21st century; since 2014,
U.S. code has required them for outlets in
most rooms in houses. If your home is an
older home, you may want to consider
upgrading your electrical system to include
AFCI's for added protection to your home.
Conventional circuit breakers only respond
to overloads and short circuits; so they do
not protect against arcing conditions that
produce erratic, and often reduced current.
The AFCI circuitry continuously monitors the
current and discriminates between normal and
unwanted arcing conditions. Once an unwanted
arcing condition is detected, the AFCI opens
its internal contacts, thus de-energizing
the circuit and reducing the potential for a
fire to occur.
Cons of AFCI's are false tripping that can
occur due to lightning storms or presence
of radio frequency energy, especially within
the High Frequency spectrum (3-30 MHz) to
include legitimate CB and amateur radio

Open Slots in an
Electrical Panel - Why open slots in an electrical panel
are considered a dangerous defect.
Electrical panels can be located just about anywhere, inside a
garage, outdoors, or in any room. That doesn't mean that every
location is acceptable or necessarily desired for that matter.
