AFCI/GFCI Receptacle provides protection against arc-faults as well as ground
faults in a single device.
In line with this, dual function AFCI/GFCI breakers offer both “combination” type
(parallel and series) AFCI protection and GFCI protection.
AFCI receptacles also offer both series and parallel protection and are referred to as
Outlet Branch Circuit (OBC) AFCI receptacles.
Why would I use an AFCI/GFCI Receptacle instead of breaker?
The AFCI/GFCI Receptacle can be a great alternative depending on the
circumstance. The AFCI/GFCI Receptacle works with any type of wiring and is not
dependent on the type of breaker in the panel. It is also easily accessible and has a
level of familiarity with users with the TEST and RESET buttons that are also present
on a GFCI receptacle.
What is an arc-fault?
The UL Standard for AFCIs defines an arc-fault as an unintentional
arcing condition (sparking) in a circuit (wiring). Arcing creates high
intensity heat (may exceed 10,000 degrees Fahrenheit) resulting in
burning particles that may over time ignite surrounding material such
as wood framing or insulation.
What causes an arc-fault?
There are a wide range of conditions that may cause arcing, which is
like an electrical spark:
Wire Degradation
• Natural degradation through age
• Humidity or heat
• Extended mechanical stress
• Extended voltage stress
Physical Damage
• Animals chewing through insulation
• Nails, tacks from construction or picture hanging driven into a
wall puncturing or damaging a wire(s)
• Extension or power supply cord damage from sharp bends or
furniture pressing on or against cords
• General cord damage
• Poor wiring or connection at devices/j-boxes
Are Dual Function AFCI/GFCI Receptacles tamper-resistant?
Yes. Leviton Dual Function AFCI/GFCI Receptacles are tamper-resistant to meet the
latest National Electrical Code
