Advanced technology helps protect against
electrical fires resulting from arc-faults.
The U.S. Fire Administration (USFA) National Fire Incident
Reporting System reported that in 2011, an estimated
47,700 home structure fires reported to U.S. fire depart-
ments involved some type of electrical failure or malfunc-
tion as a factor contributing to ignition. And, according to
the National Fire Protection Association (NFPA), arc-faults
are “the principle electrical failure mode resulting in fire”.
Arc Fault Circuit Interrupters (AFCI) were developed to help
combat the problems associated with arc-faults.
- AFCIs are designed to detect a wide range of arc-faults
to help reduce the likelihood of the electrical system
being an ignition source of a fire.
- AFCIs function by de-energizing the circuit downstream
of the device upon which an arc-fault is detected;
which could help prevent ignition and a resultant fire.
- AFCIs are now required by the National Electrical Code
®
in most areas throughout the home.
Often unseen, arc-faults can occur anywhere in the home’s
electrical system including within walls, at loose electrical
connections or within damaged electrical cords. Leviton
Outlet Branch Circuit (OBC) AFCI Devices are designed to
identify arc-faults and to respond by interrupting power to
help prevent arc-faults that may lead to a fire.
AFCI Devices
Whole house electrical safety is a tall order, but with the
new line of SmartlockPro OBC AFCI Devices Leviton has
developed a means to oer added protection from arc-
faults. Previously, the only available option for providing
the required AFCI protection against electrical fire hazards
was through the use of AFCI breakers. And, even though
there were some exceptions to the Code that would allow
for the use of AFCI protection at the receptacle level with
prescribed wiring techniques, there were no AFCI devices
available on the market. That has recently changed.
AFCI Receptacle
OBC AFCI Receptacles address the dangers associated
with both types of potentially hazardous arcing – parallel
and series arcing. Similar to GFCIs, AFCI receptacles
provide feed-through protection and are able to detect
downstream parallel and series arc-faults as well as
upstream series arc-faults. Utilizing an AFCI receptacle
oers homeowners the benefit of localized TEST and
RESET. Applications include installation in living rooms,
dining rooms, family rooms, bedrooms, parlors, dens,
libraries, sunrooms, recreation rooms, closets, hallways,
dormitories or similar areas.
Blank Face AFCI
The Blank Face AFCI oers the ideal solution for outlet branch
circuits where AFCI protection is desired but located where an outlet
is not needed. This type of application could include installing a
Blank Face AFCI in a location to make AFCI protection readily acces-
sible per the 2014 National Electrical Code. A Blank Face AFCI may
also be used on circuits feeding lighting loads and/or other loads
such as smoke detectors where a receptacle is not used.
Combination AFCI/Switch
Our Combination AFCI/Switch provides AFCI protection plus the
convenience of a single pole switch to control the lights. This
combination is ideal for kitchens, family rooms, bedrooms, dining
rooms and hallways. The AFCI Switch may be used for new circuits
or modifications to existing circuits where a switch is the first outlet
on a branch circuit.
