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.
