When i got made redundant from Asda my mum in law, who was in the process of having a kitchen fitted asked me to pop up and see her, the job was not going well, long story, short version, i kicked them, father & son off the job, the work surface was in three sections, the idiot had cut them at 90', not to the corners of the walls which were not 90', under the kitchen sink resembled spahgetti junction, there were waste pipes and water pipes going all over the place, i was not happy with the electrics and got my sparky to go over it, sure enough there was NO EARTH!! He sorted that and i said shall we check the oven as i had disconnected it prior to his arrival, he said it worked ok before, so as the pub was now open it should be ok, i was about to undo the power supply box on the wall but stopped when he said that, so he left and i connected the oven back up, switched on and it tripped the fuseboard, i think am i stupid or what, i hasten to add that i have done quite a few rewires with my mate, so connecting an oven up should not have been a problem, i undid the 6mm cable again and checked it was in the right slots, with the cable lying on the floor and the copper bent so as not to short i switched the electric back on and the fuse went again, i know my limitations so got my sparky back the next day.
The 6mm cooker connection had been wired with the earth bent out and the live wired into the earth back plate, the idiot said he had done quite a few kitchens in the Clifton area, why am i not surprised when someone gets nickel plated.
