The subject of arc fault breakers encompasses a wide range of important elements. Why are multiple AFCI breakers tripping randomly in my new home?. Square D's "TIME SAVER Diagnostics", available on breakers with a white or purple TEST button, will store the cause of the last trip: immediate trip means a ground-fault (meaning the AFCI's weak GFCI-section detected a hot-ground or neutral-ground fault). A 2-second delayed trip means the computer detected the "sounds on the wire" of an arc fault.
electrical - Old two-wire house-- AFCI or GFCI possible? As far as I know, installing AFCI (whether AFCI/breaker, AFCI/deadfront or AFCI/receptacle) does not provide "instead of a ground wire" protection. As I understand it, some AFCI/breakers provide limited GFCI functionality, but that is not at a level that really substitutes for a ground wire in the way that GFCI does. Can a surge protector prevent nuisance AFCI breaker trips?.
3 I have a problem with AFCI breakers tripping in my 2 and a half year old house. The builder's electrician said that the cause is from power surges coming from the electrical company and that I need to get a surge protector put in at the service. This perspective suggests that, the breakers are Sqaure-D QO120 single pole plug on neutral.
- Home Improvement Stack Exchange. Most arc fault breakers these days handle both. THere are also dual function breakers (DUFIES!) that handle both types of arc faults, ground faults and over-current protection. Since you said you didn't want ground fault protection, you don't want a dufie breaker.

But are there any circumstances where you're better off without them? If I won a free box of dual-function GFCI/AFCI breakers, would there be any reason not to use one for every circuit in my house?
What's the difference between these regular vs "QAF" "Plug-On" circuit .... Siemens QAF 20-amp 2-Pole Combination Arc Fault Plug-on Neutral Circuit Breaker This version differs in its name having "QAF" and "Plug-On", it's slightly cheaper, and the back looks like most circuit breakers. I've found it surprisingly difficult to learn what QAF stands for and what the different use-cases for these two options are.
AFCI keeps tripping after power outage - Home Improvement Stack Exchange. Check indicator lights on the AFCI, to determine the type of fault: ground, arcing, or overcurrent. Power cycle the main, thus "rebooting" the computer in the AFCI. In relation to this, electrical - Why don't we just use combination AFCI/GFCI breakers for .... With pretty much every circuit in a home needing one of the two types of protection (AFCI or GFCI), why don't all new homes have combination breakers installed just to be safe?
Would it hurt anything replacement - should 30 yr old home have some/all breakers replaced .... AFCI/GFCI is not available for "double-stuff" breakers (2 breakers 1 space), commonly used when a panel is over-full. The panel would need to be enlarged or external devices used.
