For both 1- and 2-pole breakers, LED indications
will appear for 5 seconds each time the AFCI is
turned “ON” and will display each time the beaker
is reset for up to 30 days after the last trip. The
last known trip condition can cleared by the
following process:
1. Turn the AFCI to the “OFF” position.
2. Press and hold Push-to-Test (PTT) button(s).
3. Turn the AFCI to the “ON” position.
4. Release PTT button(s) within 3 seconds.

Tips and Tricks
Route wires in strategic areas so homeowners and other trades are less likely
to pierce through a wire.
If possible, perform work after the other trades, i.e. HVAC and plumbing,
have completed.
Wire receptacles around the screw instead of backstabbing.
Use properly maintained tools, i.e. sharp blades.
Ensure a tight connection between light sockets and light bulb bases.
Do not overload circuit with excessive amounts of electronics.
Afrm furniture is not on or pushing against electrical wires.
Watch for blackened plugs, very damaged wires, or noisy electronics.
Electronics should be Underwriters Laboratories (UL) listed, or equivalent, and
comply with part 15 of Federal Communications Commission (FCC) regulations.
Protect electronics on surge protectors.
The PTT button is the only method recommended to verify the functionality of the
AFCIs by National Electrical Manufacturers Association (NEMA) and UL.
Test AFCIs once per month to ensure proper working conditions.

On Off Arc fault
Check wiring for the parallel and series arc
faults. Check devices for series arc faults. Use
Intelli-Arc to assist and accelerate diagnosis.
