earth fault

[Greeny]

when i touch a screw on one of my sockets in the kitchen and put my hand on the sink i get an electric shock without my breaker tripping?

If you put a voltmeter across, how many volts AC/DC?

 

[Greeny]

12V?

Sounds like you have a fault to earth on either the socket or the pipework

 

[Spark123]

Do you have a copper pipe water / drain installation?
This could possibly be put down to your main equipotential bonding not being up to spec or a fault on the socket circuit.
Main Eq bonding = the connection between the main earth terminal and where the water pipe, gas etc pipe enter the premises.

how does the voltage come out the screw???

 

[Spark123]

It might not be coming out of the screw, it may be going into the screw.

 

[Greeny]

what could cause the sink to have voltage?

 

[Spark123]

When you turn your consumer unit off, do you still get 12v?

how does the voltage come out the screw???

a live to earth fault behind the socket

it is in a purpose built flat so is my mains water supply bonded outside my flat?

Sorry, but I do not have satellite vision. Maybe you could tell us if it is there

This test should help us to tell you what the problem is.

if it is a live to earth fault why isn't the breaker tripping? i'll have to check whether there is still voltage there when i turn the fuse board off, im sure i did check that when i turn't it off and there wasn't any voltage?

its only a couple of hours drive from birmingham can't you come down and see if the bonding has been done outside of my flat?????
