Evening guys
Testing a rewire we have done and the earthing for this job is a TT system.
I have done all the tests on circuits in the house theses are all fine.
My question is how do i find ZE is it just like normal testing of this by removing Earth and going across the phase conductors. I performed this test on the installation and got 6.69 ohms not sure if this is the reading for ZE or not.
At are firm we havent got an earth electrode tester so how do i find the reading of Ra to put on the test sheet.
Sorry if its simply but never done a test on this installation as the work we do is that there is an earth provided so i thought id ask all u intelligent gents hehe
