What are Arc-fault Circuit Interrupters (AFCIs)? Why should they be installed in homes? Why mandate AFCIs for newer homes when statistics show the majority of problems have occurred inolder homes? How do you know AFCIs will prevent fires andsave lives? Are AFCIs expensive? Do AFCIs interfere with smoke alarms and appliances, or trip unnecessarily? What is the NEC?
Are AFCIs expensive?
The cost the enhanced protection directly related
to the size the dwelling and the number circuits
installed. Arcing the principal electrical failure mode
resulting fire. By
eliminating significant source electrically related
fires, future statistics will demonstrate reduction in
fires electrical origin.
. The NEC evolving
document, developed through open consensus
process.S. The NEC’s
mission provide practical safeguards from the
hazards that arise from using electricity. 2005,
there were estimated 20,900 home structure fires that
involved electrical distribution lighting equipment
and resulted 500 civilian deaths, 1,100 civilian injuries,
and $862 million direct property damage. Installation errors can occur
at any point. Even for larger homes
with more circuits, the cost increase insignificant

How you know AFCIs will prevent fires and
save lives?
Since 1999, AFCIs have been thoroughly field-tested. Once installed, AFCIs provide protection
for the life the electrical system. More
importantly, every new home will become older home
with time.Keeping Your Community Safe and Energized!

What the NEC?
The NEC the National Electrical Code.
Why should they installed homes?
AFCIs will save lives and make homes safer. AFCIs prevent such damage errors from
causing fires. Roughly
half these fires cited arcing factor contributing
to ignition.
Why mandate AFCIs for newer homes when statistics
show the majority problems have occurred in
older homes?
Fire safety officials recommend the use AFCIs all
dwellings but recognize that installation easier and
more affordable during original construction. The type AFCI currently
available commercially 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 the
circuit before fire can start. Consumer
Product Safety Commission, and many other experts
have found AFCIs reliable and effective.
These state-of-the-art devices identify problems that
current circuit breakers are not designed protect
against, which can result what appears an
unexplained circuit breaker trip. Fire safety officials endorse
AFCIs significant step forward electrical fire safety. new edition issued every three years. More years use mean more opportunities

Do AFCIs interfere with smoke alarms and appliances,
or trip unnecessarily?
