The Arc Fault Detection Device… again.

whjohnson
Some humourous but valid observations on AFDDs, the state of the industry, the wiring regs and future amendment requirements.

He also attempts to build a AFFD tester which electrically tests rather than relying upon the mechanical action of the test button on the device itself.

    Looking at this data, we should see a reduction in the rate of decrease of fires starting about 12 years ago when AFDDs were mandated in the USA. There appears to be no statistically significant change in rate, which means that AFDDs in new or uprated installations have made no useful difference to the number of fires. This is fairly damming! The overall rate is decreasing by about a third in the last 40 years, probably due to a change from valve (hot) to solid-state electronics among other things, although the number of appliances has undoubtedly increased greatly. The largest cause of fires by a large factor is cooking, should this be banned or made hugely expensive?
