Re: Tell us about your faults !

:rolleyes:Heres and intresting one i came across on a routine PI ,NIC regesterd company replaced the CDU 2007 but what struck me was the earth type TNS or TNCS ,obviousley he didnt check ,i though it was obviouse TNS , but the 16mm from the main CDU was connected to the bock on the side of the cutout and the bonding and earths for the other CDU's were from the outer of the supply , testing confirmed it was a TNS and the earth block on the side of the Cutout was connected , so the earth for the distboard was comming via the cpc of the immersion heater nice eh lucky the bonding was in place ,if only he'd tested it properly then he'd spotted his error ,
