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.

    So in my house AFDD will not detect series arcs on the socket ring or the lighting circuits.


    If that’s true they are about as much use as a chocolate teapot in my house and most of the other houses in the UK.


    The loads on the lighting circuits are less than 2 amps each if I turn all the lights in the house on at the same time and that’s at the start of the circuit, individual switch drops supplying one LED lamp in a pendant on bedrooms are only carrying around 40 milliamperes, not the 2 amps or more required for an AFDD to work correctly.


    Still the switches should not cause an arc that results in nuisance tripping.
