Called to a property yesterday after the customer had been advised to call an electrician by an engineer who had done some work on there cooker. I arrived and was directed towards a socket in the kitchen. The lady couldnt really explain what the engineer had told her.
I plugged my multifunction tester in and immmediately realised there was a problem. The display wasnt showing a voltage between live and earth but was showing voltage between live-neutral and neutral-earth. I removed the socket front and saw that the live and neutral conductors had been connected into the wrong terminals. Once i had sorted this out i plugged my tester in again to try and do a Zs test, but i was unable to as there was still voltage showing between neutral and earth. I tried another socket in the kitchen on the same circuit and was able to perform the test, getting a reading of 500ohms. The system is a TT although a quick look at the mains suggests there might be PME available.
I went around various sockets on the circuit and was left a little bit baffled as some would let me perform a Zs test and others wouldnt as it was indicating a voltage between neutral and earth. When i initially removed the socket with reversed polarity i used my tester across neutral and earth and was getting a voltage of around 30v. I have advised the customer to have a EICR, which she is going ahead with. I wasnt able to spend any great deal of time there last night so sorry for any lack of other information. As already said i will be returning to carry out an EICR so will hopefully get to the bottom of the issue then, but in the meantime any suggestions, advice greatly welcomed.
