Hi. I have a question about earth leakage meter usage/selection.
I see that people say one should test the live wires not the earth for reasons you guys probably understand. However earth leakage meters with large Jaws to loop around both tails are much more expensive.
Can I use a combination of insulation resistance testing and earth leakage testing on the earth to achieve the functionally equivalent result? I'm also assuming I'd have to test the fixed wiring and pat test the device.
I only started thinking about this but it seems reasonable so far apart from...
What if the device I'm pat testing has internal switching and the earth leakage only occurs intermittently?
Also any tips on what I should purchase are welcome.
Thanks
