Hello
I have been asked to do a bunch of pat testing and I have a couple of questions that hopefully someone has an idea about.
I have a Fluke MFT and a clamp meter and have built myself a socket lead which allows me to plug an appliance directly in to my tester. This allows me to do IR with line and neutral linked. I can do earth continuity on class 1 equipment with a probe and alligator on to the earth pin on the plug and an exposed metal part. I am planning to build a earth leakage tester by removing the earth from a short extension lead and coiling it 10 times to amplify the signal and clamping on to the coiled cable. I believe this will work and for class 2 equipment (and this is where it could be getting sketchy) I am thinking of coiling the live and neutral around 10 times (in the same direction) and I think that this should detect and amplify any imbalance so that an ordinary clamp meter can detect it. The alternative would be to dissect an RCD and amplify that signal to test, but I think the first option would achieve the same result. All thoughts welcome.
