Re: testers, inspectors, & afci's
I spoke to an engineer at UL today and he said there is nothing in writing anywhere that says the test button is the only way to test an AFCI breaker. What he did say is that it is the only effevtive way to test the breaker as it checks all the internal components to insure that they are working properly. The testers can not do what the button does so the button should be the test you use. If the button works the breaker works. That is the test that UL uses and endorses. Same can be said for the manufacturers.
