- ★ I turn on my RT310 AFCI/GFCI Outlet Tester when it is not plugged into an outlet and I see the Power light, the Non-Energized light, and the Open Hot light all illuminate, is this correct?
- Are there some cases where the AFCI breaker will not trip with the RT310 Receptacle Tester?
- The AFCI function on my RT310 sometimes will stop working, but when I try later it works fine—what is happening?
- Do the Klein Tools RT105, RT110, RT210 Receptacle Testers require batteries?
