Hi, my single oven needs a new thermocouple and the wife is getting a bit twitchy about it. Her father has offered us his old double oven that he just happened to be holding on to. Soooo my oven was a 2.8 kW on a 2.5mm t + e. Looking on line this looks to be a 5.3 kW double oven. Will it be ok on my 2.5mm supply while I wait for parts? I dont really want to be pulling in cables. Thanks in advance!
