No voltage on live-neutral but voltage on live-earth

[Ellsa100]

Hi there

I recently replaced the downlight fittings in my bathroom so they are now GU10 LEDs (previously they were MR16s). The lights are IP65 and connected to a 30mA RCBO.

The light was working fine until recently. I was fiddling with the light fitting to correct the ceiling which had been damaged in the swap over - which involved taking out the fitting and replacing it - and now the LED isn’t working. I used a multimeter to check the voltage and there is 240v between live and earth but 0v between live and neutral. It seems like the neutral has been disconnected somehow.

The wiring is difficult to access as It is in the ceiling void - so it would be tricky to figure out the issue with the neutral wire. Would it be OK to use the earth wire to complete the circuit given thedownlight is double insulated?

thanks!

Like I said opinions differ... messages and icons can often be misconstrued. My reply to you was justified.

Surely all Australians can't be old women?

The first test is a continuity test followed by the earth impedance test.


the continuity test would show that the earth is connected to the house earthing system but would not show if it was safe from cutting the electricity in the correct time.

if you assume that there is no secondary fault, you could do this using the earth at the light with the earth in a socket or even the water pipe .

I and others I know have fitted a wire to the earth pin in a plug (no live or neutral) and use this as an earth point for comparison.
