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.

    Chris, the wobbly choc block has been done, by John Ward.

    Try about 5 to 6 mins into  this video for an idea of how well it works with a light load  for that sort of fault, or about 23 mins into this one, for a higher fault current.. I found it underwhelming in the extreme in both cases.
