Hi, I have purchased a new Neff hob. In the box there is a length of 5 core cable. The instructions show 3 wiring methods one of which shows the black and brown joined acting as the live and blue and grey joined as neutral. The hob uses 7.7kw. In my opinion the cable looks a bit thin to be for a 32amp appliance however if it’s supplied with the hob surely it must be suitable? I unfortunately don’t know what size cable it is and it doesn’t mention anywhere in the instructions or specification pages. I will attach pictures.
