80 volts on earth conductor

[jimra56]

hi,

i have 80 volts between my earth and neutral, what's the most likely cause?

Between E&N.....where.....on a particular circuit, at the origin, in your toaster??????

If its a TNCS supply it could be a neutral fault , the path from the neytral is broken and the returns back up the earth to the cdu , are you getting shocks off any metal appliances , or the simpler thing is you have no earth connection at some point ,as lenny has said where are you getting the 80 volts

Hi jimra56,

I came across the same problem and traced it a damp area around the socket behind the washing machine, water had been leaking from machine and soaked the wall and the socket was badly installed. Was called to house because owner was getting shocked when she was around her machine.

As per Lenny where are you measuring each from, i.e where is you meter connected to the earth point and where is it connected to the neutral? You may have a fault similar to what I experienced.........
I had an interesting fault the other week whilst checking that Class 1 metal socket fronts were earthed. Admittedly it would have been best to carry out whilst dead, however this was just a quick check for peace of mind after doing a different job at night. I found 50v between the metallic light switch front and the main earth terminal at the consumer unit. When the light switch was switched on there was 100v. Further examination showed that the CPC (Earth) to the light switch was disconnected in the ceiling rose. Tests of the earth at the rose proved ok, IR tests on the switch cable proved ok. Reconnection of the CPC (earth) eliminated the problem. All I can put this down to is induction from the live conductors to the CPC conductor. One to look out for though!!
