[QUOTE="SPECIAL LOCATION, post: 507648, member: 250"] I am not convinced the new hob will draw "at least" 20 amps.. As this would sugget the smallest single element is over 4.5kWatts ?? Are you sure its not UP-TO 20amps? i.e. all hob elements on together would draw around 4.6 to 4.8kWatts.. There is a principle know as diversity that allows for the fact that every feature of an oven/hob is not on simultaneously... So you don't always have to apply the maximum possible power an appliance may draw... ' How long is the existing cable length supply from oven to CU? What installation methods are used for the existing cable? How easy is it to run an additional circuit back to the CU? IF relatively straight forward then it could well be beneficial to either install a new circut, or upgrade existing to 10.0mm. Guinness [/QUOTE]
