Which electrical tester would you use for both AFCI and GFCI? I know there is one tester for GFCI, but what about AFCI? What would you use or do?
The test button on the unit is the only manufacturer approved method of testing both AFCI and GFCI.
I also have what @pgiannino shows. It is an alternate method to test for function other then the breaker push button. Do not use it much, but it works great.
