Hi There
Can someone advise on the following, I have fitted a new consumer unit ie, Volex 100amp split load, with a 80amp/ 30ma RCD
With the mains switch on the consumer unit switched off, and making sure all light and socket switches throughout the house were in the 'OFF' position I carried out the following procedure in the consumer unit. I placed a tester across neutral and earth, - all clear, live and earth, - all clear, live and neutral , - all clear. I then turned on the power, and checked all sockets with a socket tester plug. All three neons lit up in the plug indicating that the wiring was correct. I then plugged in an extension lamp on each socket plug - bulb lit up with no problems. As a further test I plugged in an electric drill and directly I pressed the 'On' switch the RCD tripped out in the cu. This happened to the three 30amp ring mains, ie upstairs downstairs, and kitchen . I then used my socket tester plug again and only two neons lit up indicating a neutral fault. This happened on all three ring mains. On checking the earth the only electricity supplers earthing bond is under the floorboard and attached to the lead water pipe. I have since cross bonded the gas and water pipe with 10mm earth and run it to the cu. however the RCD keeps tripping out. As a further test, I connected the neutral wires from the downstairs ring main to the neutral bar in the cu which is not covered by the RCD - no problems at all. Finally, when pressing the 'test' button it only trips when you wiggle the actual RCD. any advice on the above would be most welcoming!
