For me, that makes it especially important in bedrooms, living areas, and other parts of the home where I want better protection for my family and property.
Another reason I see it as necessary is that it supports safer, more modern electrical protection.

My Buying Guides on Square D Qo Afci Breaker
What I Look for First
When I shop for a Square D QO AFCI breaker, the first thing I check is compatibility. I always make sure the breaker matches my Square D QO load center, because not every breaker fits every panel.
