Hi, Anyone give advice? I am not totally green when it comes to electrics- i have done most of my ownand still do, the problem is my uncle phoned me earlier saying he had wired up his new cooker with 6mm cable but every time he switched on it was tripping out. I was trying to help him out over the phone but then he said" AH Is see what i've done, I put the earth wire to wrong connection at the cooker end. Now he says he has re-wired it correctly but there is no power at all. would his previous mistake damaged the cooker?
