Also this video. Most importantly around 25 minutes in, the author shows a breaker tripping magnetically vs thermally:

Yeh, but the fire was started by a propane torch not an electrical arc. Why worry about electrical arcs when the fire has already been started by another cause? Illogical.


Edit, add.


In the U.K. we have the wonderful 13 Amp. plug made to B.S. 1363. Have you ever heard of it? It contains a fuse. The fuse rating can popularly be either 3 Amp or 13 Amp, but other sizes are available like 5 Amp or 10 Amp. Flexes are protected by these fuses which are less in value than the 20 Amp circuit breakers referred to in the dated video.

Illogical indeed, but sadly this was enough to get AFCIs taken seriously.


Of course I've heard of BS 1363 plugs. AFCIs were supposed to to mimic their their ability of clearing flex faults rather quickly.

Sometimes A.F.C.I.s work too quickly too.
