51,800 home
structure fires
reported to U.S.
fire departments
involved some
type of
electrical
failure or
malfunction as a
factor
contributing to
ignition. These
fires resulted
in 451 civilian
deaths, 1,641
civilian
injuries, and
$1.2 billion in
direct property
damage.

ELECTRICAL
CIRCUIT-INTERRUPTERS
|
|

All
AFCIs
and
GFCIs,
whether
circuit-type
or
breaker-type,
should
be
installed
by a
qualified
electrician. Test
AFCIs
and
GFCIs
after
installation
and once
a month
thereafter
to make
sure
they are
working
properly. Replace
defective
AFCIs
and
GFCIs
immediately.
A
defective
device
may
create a
false
sense of
security
to those
who do
not know
that it
is
non-functional. Choose
AFCIs
and
GFCIs
that
carry
the
label of
an
independent
testing
laboratory
and
always
follow
the
manufacturer's
instructions.
|

AFCI
GFCI
|
Protective
devices capable
of responding to
overloads and
short circuit,
such as circuit
breakers, have
been available
for a number of
years. Newer
technologies now
provide enhanced
protection from
arcing or
ground-faults,
which may
prevent fires or
shock.
AFCIs (arc-fault
circuit-interrupters)
When an
electrical
switch is opened
or closed, an
arc, or
discharge of
electricity
across a
circuit, occurs.
Unintentional
arcs can occur
at loose
connections or
where wires or
cords have been
damaged. Such
arcs can lead to
high
temperatures and
sparking,
possibly
igniting
combustibles.
AFCIs (arc-fault
circuit-interrupters)
protect against
fire by
continuously
monitoring the
electrical
current in a
circuit and
shutting off the
circuit when
unintended
arcing occurs.
These devices
are designed to
discriminate
between
unintended
arcing and the
type of arcing
that occurs when
a switch is
operated.
GFCIs
(ground-fault
circuit-interrupters)
A ground-fault
is an
unintentional
electrical path
between a source
of electrical
current and a
grounded
surface.
Electrical shock
can occur if a
person comes
into contact
with an
energized part.
GFCIs
(ground-fault
circuit-interrupters)
can greatly
reduce the risk
of shock by
immediately
shutting off an
electrical
circuit when
that circuit
represents a
shock hazard
(i.e., a person
comes in contact
with a faulty
appliance
together with a
grounded
surface). GFCIs
can be installed
in a circuit
breaker
panelboard or
directly in a
receptacle
outlet.
Facts and
figures
- AFCI
installation
is required
by the National
Electrical
Code®
(NEC)
in bedrooms
of new
residential
construction
(effective
as of
January 1,
2002).
Bedrooms
were
selected as
the first
area in
which to
implement
this
requirement
because of a
history of
fires there.
-
GFCI
installation
is required
by the
NEC for
receptacles
in kitchens,
bathrooms,
outdoor
areas,
basements
and garages
in new
residential
construction
because of a
history of
shock
hazards in
these areas.

National
Electrical Code

What are
Arc-Fault
Circuit
Interrupters
(AFCIs)?
The 2008
National
Electrical
Code® (NEC®)
requirement for
AFCI protection
considerably
expands this
fire prevention
technology to
the majority of
circuits
installed in new
and renovated
homes. The type
of AFCI
currently
available
commercially is
a
next-generation
circuit breaker
that not only
provides the
conventional
safety
functions, but
its advanced
design also
rapidly detects
potentially
dangerous arcs
and disconnects
power in the
circuit before a
fire can start.
Fire safety
officials
throughout the
U.S. endorse
AFCIs as a
significant step
forward in
electrical fire
safety.
Why should they
be installed in
homes AFCIs
will save lives
and make homes
safer. According
to the U.S. Fire
Administration,
each year home
electrical
problems cause
about 70,000
fires, resulting
in 485 deaths
and $868 million
in property
loss.
Why mandate
AFCIs for newer
homes when
statistics show
the majority of
problems have
occurred in
older homes
Fire safety
officials
recommend the
use of AFCIs in
all dwellings.
While it is true
that fire
statistics in
many cases are
derived from
older dwellings,
damage to
appliance cords
or to wires
hidden in a wall
can occur
regardless of
the home’s age.
In addition,
incorrectly
performed
electrical
installations
can occur in
both new and old
homes. As
technology
evolves and the
NEC is revised,
the enhanced
level of safety
is typically
required only in
new construction
that is subject
to the latest
adopted edition.
Homes wired per
the 2008 NEC
will have the
majority of
their circuits
protect by AFCIs
for the life of
the electrical
system.
How do you know
AFCIs will
prevent fires
and save lives?
Since 1999,
AFCIs have been
thoroughly
field-tested.
Underwriters
Laboratories,
the National
Association of
State Fire
Marshals
(NASFM), the
U.S. Consumer
Product Safety
Commission, and
many other
experts have
found AFCIs to
be reliable and
effective. By
eliminating a
significant
source of
electrically
related fires,
future
statistics will
demonstrate a
reduction in
fires of
electrical
origin.
Are AFCIs
expensive
The cost of the
enhanced
protection is
directly related
to the size of
the dwelling and
the number of
circuits
installed.
Current retail
prices of
AFCI-type
circuit breakers
at several
national
building supply
chains are in
the range of $35
to $40 per unit.
Even for larger
homes with more
circuits, the
cost increase is
insignificant
compared to the
total cost of
the home,
particularly
when the
increased level
of safety is
factored.
Do AFCIs
interfere with
smoke alarms and
appliances, and
trip
unnecessarily?
AFCIs do not
interfere with
power supply
reliability.
These
state-of-the-art
devices identify
problems that
current circuit
breakers are not
designed to
protect against,
which can result
in what appears
to be an
unexplained
circuit breaker
trip. By
actually
identifying
these problems,
residents are
safer.
What is the
NEC? The NEC
is the National
Electrical Code.
The NEC’s
mission is to
provide
practical
safeguards from
the hazards that
arise from using
electricity. It
is the most
widely adopted
safety code in
the United
States and the
world, and it is
the benchmark
for safe
electrical
installations.
The NEC is an
evolving
document,
developed
through an open
consensus
process. A new
edition is
issued every
three years.
TAMPER-RESISTANT
ELECTRICAL
RECEPTACLES

What are
tamper-resistant
electrical
receptacles and
what is the new
requirement?
The 2008
National
Electrical
Code®(NEC®)
will require new
and renovated
dwellings to
have
tamper-resistant
(TR)
receptacles.
These
receptacles have
spring-loaded
shutters that
close off the
contact
openings, or
slots, of the
receptacles.
When a plug is
inserted into
the receptacle,
both springs are
compressed and
the shutters
then open,
allowing for the
metal prongs to
make contact to
create an
electrical
circuit. Because
both springs
must be
compressed at
the same time,
the shutters do
not open when a
child attempts
to insert an
object into only
one contact
opening, and
there is no
contact with
electricity.
Tamper-
resistant
receptacles are
an important
next step to
making the home
a safer place
for children.
Why require
tamper-resistant
electrical
receptacles?
Each year,
approximately
2,400 children
suffer severe
shock and burns
when they stick
items into the
slots of
electrical
receptacles. It
is estimated
that there are
six to 12 child
fatalities a
year related to
this.
If homeowners do
not have
children, are TR
receptacles
required?
Yes. Owners or
tenants of homes
and apartments
change
frequently. In
addition,
exposure to
electrical shock
and burn
accidents are
not limited to a
child’s own
home. Children
visit homes of
relatives and
friends who
don't have
children of
their own. This
requirement
ensures all new
homes and
apartments are
safe for
children,
whether the home
is their own or
they are there
on a temporary
basis.
Do TR
receptacles
require greater
insertion
strength than
standard
receptacles?
TR receptacles
require
comparable force
to other
receptacles. The
insertion force
may vary
depending on the
newness of the
device to the
shape or style
of the plug
being inserted.
Are TR
receptacles
costly? No.
The projected
cost of a TR
receptacle adds
about $0.50 to
the cost of an
unprotected
receptacle.
Based on current
statistics, the
average home has
about 75
receptacles
resulting in an
overall added
cost of under
$40. This amount
may vary
slightly based
on the type and
style of TR
receptacle used.
This minimal
increase in cost
buys a
significant
increase in
electrical
safety for
children.
Shouldn’t people
accept
responsibility
for their
children and
teach their
children not to
stick items in
receptacles?
Accidents
involving
children and
receptacles
cannot be blamed
entirely on poor
parenting. They
involve people
who look away
for a moment,
only to face
undue tragedy
and pain as the
result of a
child's
curiosity. The
NEC’s
mission is to
provide
electrical
safety in the
home. TR
receptacles are
a simple and
easy way to
protect children
from serious
injuries that
continue to
happen every
year.
Why are TR
receptacles
preferred over
products such as
receptacles with
caps or with
sliding
receptacle
covers?
Receptacle caps
may be lost and
also may be a
choking hazard
for some ages.
Children can
learn to defeat
sliding
receptacle
covers when they
watch their
parents. TR
receptacles
provide security
against the
insertion of
objects other
than cord plugs
into the
energized parts.
AGING
ELECTRICAL
SYSTEMS AND
SAFETY
Our lives depend
on the safe use
of electricity
in our homes,
but safety
doesn’t just
happen.
Electricity
continues to be
a leading cause
of home fires in
the United
States. In fact,
according to the
National Fire
Protection
Association,
fires starting
in electrical
systems or
lighting
equipment damage
24,000 homes and
kill 320 people
each year. What
some homeowners
might think of
as a "minor"
electrical
problem can lead
to a dangerous
or deadly fire.
Your family and
your home’s
smoke alarms may
not detect an
electrical fire
until the home
is fully
engulfed, giving
you less time
and fewer
options for
escape.
Older Homes and
Electrical
Hazards
Older
homes can have
serious hidden
hazards that
require
inspection and
repair by
electrical
experts. That’s
why a recent,
first-of-its-kind
study from the
Fire Protection
Research
Foundation
carefully
examined
electrical risks
and hazards
present in older
homes.
About the Study
The
Residential
Electrical
System Aging
Research Project
was based on a
thorough
inspection of
electrical
systems and
equipment in a
sample of older
homes across the
country. This
detailed
assessment
included a look
within and
"behind the
walls" of each
home, along with
testing of key
electrical
system elements.
* The
study closely
examined
electrical
systems and
devices from 30
homes in 10
states across
the U.S.
* The majority
of homes in this
study ranged in
age from 25
years to more
than 90 years.
Two of the homes
were more than
100 years old.
* For each home,
wiring and
electrical
systems, along
with specific
devices, were
carefully
inspected. After
examining the
homes,
technicians also
collected
certain key
electrical
system elements
(receptacles,
service entrance
panels,
luminaires,
junction boxes,
etc.) and sent
them to
Underwriters
Laboratories
(UL) where they
conducted a
detailed
laboratory
analysis to
determine how
the elements
performed after
years of service
in the field.
Findings from
the Study
The
results of this
unique study
show that the
vast majority of
potentially
hazardous
electrical
conditions in
these older
homes were
caused by:
* Failure to
meet well
recognized,
proven safety
code provisions
found in the
National
Electrical Code®
(NEC®)
* Failure to
properly install
and maintain
important
electrical
equipment It is
important for
homeowners to
remember that
many hazards can
exist in older
homes.
* Some older
equipment and
wiring appeared
well-maintained,
performing
effectively and
safely.
*Other older
homes had
dangerous
electrical
conditions.
* There are some
simple steps
homeowners can
take to protect
their families
and homes from
electrical
hazards.
* Homes should
be inspected by
a qualified
electrician who
is looking
specifically at
the electrical
system. A
thorough review
of the
electrical
system, such as
that described
in the NFPA 73
Electrical
Inspection Code
for Existing
Dwellings,
is particularly
important when
purchasing an
older home.
* When you
have electrical
work done, use a
professional
electrician.
