Well since i doubt there is actually anyone old enough to recall the introduction of molded case breakers I will make the assumption that the conversations were just like this one. Who would install a one dollar circuit breaker when I can use a 10 cent fuse and achieve the same degree of safety. Then there was XO and bull dog breakers etc. Regular circuit breakers took a number of iterations to get them to today. The science is always growing.
My real issue is how we as consumers become the test bed for these emerging technologies. Just look at the development of Windows. How many iterations until a new operating system is released and it actually works better than previous versions.
As for the subject of this thread. AFCI technology has made a great promise of improved safety but we all testify that it has included a lot on unfulfilled promises yet to be realized. It has great potential to add a real improvement over what was here before.
