I'm in the final stages of a partial rewire and am in the process of preparing the current kitchen socket radial circuit for connection to the Consumer Unit.
Continuity Testing gave R1+R2 = 0.25ohms. However, the Line/Neutral to earth IR test gave 1.56Mohms.
I broke the circuit down and tested each individual leg and got 200+Mohm readings.
I then connected each individual leg of the circuit and tested each time. Everything was fine until I connected one socket to the backbox and took the reading - it was 1.49Mohms.
This socket has a surface mounted metal backbox. The IR reading is in excess of 200Mohns until I connect the socket to the backbox - remove the screws and everything is fine.
Question is, will replacing the metal (surface mounted) backbox with a plastic version cure the problem or does the problem lie with the socket itself?
Any clues or help would be appreciated.
