I have a Zanussi oven and the heating element needs to be changed. In my kitchen i have installed a new oven whilst i fix the Zanussi. The wire for oven cookers are thick grey flatter grey ones and the copper wire is thicker. Whilst I am fixing the Zanussi oven I will be attaching a normal 13amp plug. I will be changing the heating element. Will this be a problem? If and when I fix the Zanussi i will like to refurbish it and sell it on and need to show it working.
