Hi All
Been called out to an issue a clients daughter has had for a while
Basically, when the earth pin on the cooker plug touches the earth on the socket (metal plates, so front or plugged in) the RCD trips. You can plug anything else in and the sockets work. With the gas bayonet unplugged the cooker no longer trips. Checked the cooker with a Megger and can't find an issue there with insulation and have continuity from earth pin on plug to gas bayonet. They have a combi boiler thats cross bonded and not tripping anything and have checked the bond on the gas, cleaned it up and followed it from meter to MET. Have checked the sockets and no probs there and have replaced the RCD from 1970's to nice modern one, The system is TNS. What am I missing.
BTW first time stumped in many years!
