I have a 240V+-10V 2 Wire Single Phase (UK) supply with TT earth bonding (earth rod).
The breakers are double pole.
The issue is with a lighting radial circuit.
This is a new electrical installation and the electricians are about to finish.
The lights that are connected to the circuit power up fine.
One light is not yet connected to the switched live.
With one CB on I probed (using a multimeter, I aware this might not be the best way to test) between Neutral and earth and there was 230 Volts. I probed at a fixture (neutral to earth) and again, 230 Volts
- What is an acceptable voltage between Live/Line and Earth?
- What is an acceptable voltage between Neutral and Earth?
- Should there be voltage between live or neutral to earth?
Is voltage between neutral and earth normal or could there be a fault?
This video states that there should be 0-0.5V between earth and neutral
This post on Quora states that
A rule-of-thumb used by many in the industry is that Neutral to ground voltage of 2V or less at the receptacle is okay, while a few volts or more indicates overloading; 5V is seen as the upper limit.
