As I understand it, there are permitted routes for buried cables, i.e. vertically or horizontally from an electrical accessory or within 50mm of a room corner/edge.
Now consider a cooker. Most cooker isolator switches are installed between the adjacent base unit and adjacent wall cupboard, so its always to one side of the cooker rather than above it for safety reasons involing burns and water ingress itno the isolator switch.
So far so good as a cooker cable from the CU can be made to go to this isolator swtich vertically or horizontally.
Now consider cooker outlet box. These are often placed behind a cooker, particularly free standing ones.....
So does this mean that one cannot run the cable between the isolator switch and the cooker outlet plate diagonally but running aross then down or down and then across is OK?
bending 6mm2 cooker cable into 90 degrees and keeping it flat is going to be interesting!
Having said that, I have stripped out kitchens in the past and found a diagonal run of 6mm2 cable from teh cooker isolator switch and the cooker outlet plate.....
