EICR Failure - lack of continuity

[Neptune]

OK. I had overlooked the single probe safeguard.
In conclusion, if I found myself in the rare situation where Neutral and Earth had a broken continuity, just touching one of my probes on Live and the other on N/E will provide an indication of power. Enough for me to be suspicious. I was concerned that there would be absolutely no indication of power in this situation and I could potentially be working on a hot circuit.

Yes, once I have done the test I would isolate the power before - test again - then start work. There may also be situations where I am using these tests to identify the Live wire (thinking of a SL in a lighting circuit scenario)

I think you've cleared that up and put my mind at rest Thanks

For your safety .. A known good earth -- Plumbing done in bonded copper ...Could give you a reference for your safety.

..but Skilled electricians will be more on the ball for the un-expected
safety risks .. Locate -identify & analyses whole situation .(from experience)

... (an know he's not leaving a trail of secondary faults from disturbing wiring thats already damaged / beyond saving ...)

When using the 2 pole tester to check for voltage, always test it first on a known live source and again after testing.

While chances of failure are slim, you only need to be unlucky once.
