2391 Question

[DoBBY]

Where would each probe be connected on an earth fault loop impedence test, using 3 leads?

Can't find anything in GN3 that tells me, if anyone has the answer or can point me in the correct direction of GN3 I would be grateful.

Cheers DoBBY

Clip earth and neutral together for 3 lead test.

If you have some time before the exam try and get the practical guide by Christopher Kitcher
ISBN 978 0 7506 8449 1 plenty of actual pictures in that helps to make sense of GN3

In the practical guide it shows for a ze test that the neutal and earth lead of a three lead tester are connected together. When testing on a cooker circuit with a three lead tester it shows the neutral lead on the neutral connection and earth on the earth.
