Sorry guys another question.
Earth electrode test using a Earth Fault Lopp Tester.
One book i have says connect lead to incoming phase conductor at the supply side of the main switch and test
IEE exam success says connect to outgoing phase of main isolator. Which i assume is not the supply side.
1. Does it matter which side its connected to, my understanding is supply side
2. When some books state about connecting a Neutral during this test does it mean if you are using a 3 lead or 2 lead. 3 lead connect neutral, 2 lead don't.
Thanks
