Fred down the pub said that I can save money by not using a qualified sparks to test my R.C.Ds. He said that I can make my own R.C.D. tester. Is it safe?
You can't use any old light bulb as an earth leakage test. You need to consider the minimum trip current specified. The test device must draw this minimum current, so the resistive element must be suitably chosen.
