I am replacing a Hygena single electric oven (2.2KW) with a 2nd hand Belling single electric oven (2.3KW) that has been fitted with a 3 pin plug. On pulling out the Hygena, I noticed the separate electric hob (situated on the work top above the oven) was wired directly into the back of the oven into the same slots where the mains cables were also feeding power to the oven. The mains cable goes to a consumer protection unit with a switch, above the unit and to the right of the hob. Can I simply remove the old plug and lead from the Belling and wire in the mains cable and hob as it was attached before. I am worried that I am not protecting the oven with appropriate fuses (even though it is a very similar power to the hygena)
