The Arc Fault Detection Device… again.

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.

    I wonder if anybody has done an experiment with an AFDD using a loose connexion? It would be easy enough - just poke a bit of cable, preferably stranded such as 1.5 mm² singles, into a wee choc-block and don't tighten the screw.


    If an AFDD tripped, then all well and good. If not, it would be interesting to see whether an ordinary (nylon?) choc-block would melt. In that event, in a class I device, presumably ADS would operate.
