AFCI In Bathrooms

[SSDriver]

Note that the original print of the 2020 handbook had an error in 210.12(A). An errata (correction) was issued on Feb 6, 2020 to correct that language and include all the rooms just like the regular code book has. I'm sure subsequent print runs and the online version have this correction already incorporated in it.

Thanks for that info. My version I just bought a month ago was not fixed.

I still want to see ANY test that shows an AFCI working that is not tripping on GFCI or with the help of a special machine that boosts voltage higher than utility voltage to trip an AFCI.

I have seen many receptacles burned and melted on AFCI circuits that weren't tripped

FWIW:
I have found that on a few trouble shooting occasions that the AFCI breaker was tripping under arcing conditions.

My help found a few of those as well. Fortunately we didn't get a lot of AFCI calls because our customer base was not residential work.

I haven't run into one that I am confident was tripping because of arcing yet. Had a melting down receptacle (heater was plugged into it) recently that I first thought I seen my first AFCI trip due to such conditions, but continuity test showed that it had developed a ground fault - so most likely was tripping on GFPE function.
