I went to a existing customer last week to remove a hob and install a new hob, the cooker switch was installed myself a couple of years ago, but when connected up, every time I screwed the cooker switch back, the LED light on the switch keep going out, so undone it again and then it worked, after disconnecting the main cable from the consumer unit, the wires were giving me 240volts, but not all the time, this lead for me to give the news to my customer that it needed a rewire.
Returned today, and tried to chase the cable back, but noticed that the outer colour of the cable was a lighter colour than the one going into the cooker switch, so this meant the cooker hood metal hood has to be removed, and some of the wall needed to be chased out to identify this.
So, it came to my conclusion that a piece of cable must have been added, but the splash back needed to be removed also, when this carefully was, and bang, I was spot on, the cable from the board was connected to a 20 amp connector block, and a piece of 6mm added on with the wires not properly connected, causing melting and blackness, this has overheated, and done by a ' diyer ' and would have caused a fire.
I remove all and installed a larger connector block with a 6mm cable.
Left all working but the wall in a mess.
