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 departments involved
some type of electrical failure or malfunction as a factor con-
tributing to ignition. These fires resulted in 418 civilian deaths,
1,570 civilian injuries, and $1.4 billion in direct property damage.
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; ideally
preventing 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 electrical cords accidently damaged by
impinging furniture. Leviton Outlet Branch Circuit (OBC) AFCI
Receptacles are designed to identify arc-faults and to respond
by interrupting power to help prevent arc-faults that may lead
to a fire.
AFCI Receptacle
Whole house electrical safety is a tall order, but with the new
SmartlockPro OBC AFCI Receptacle Leviton has developed a
device to offer added protection from arc-faults. Previously,
the only available option for providing the required AFCI protec-
tion 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 an AFCI receptacle
with prescribed wiring techniques, there were no AFCI recep-
tacles available on the market. That has recently changed.
Leviton’s OBC AFCI Receptacle addresses the dangers associ-
ated 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
arc-faults, both parallel and series, as well as upstream series
arc-faults. Utilizing an AFCI receptacle also offers homeowners
the benefit of localized TEST and RESET.
