[QUOTE="Mike Noc, post: 486553, member: 31795"] As part of a kitchen upgrade I now have a new double oven and hob to install. Total power consumption for the new oven is 4.2kW, and for the new hob 6kW. The oven manufacturer recommends a minimum 25A MCB and the hob manufacturer states that a 25A MCB must be fitted. Both units specify 2.5mm heat resistant cable, and the oven manufacturer states that the maximum length for that cable is 2 metres. Including free cable for allowing the oven to be removed from its cabinet (something whovever fitted the old oven didn't think to do!) the total cable run is around 5 metres. The hob cable length is less than 500mm. The circuit currently uses a 32A MCB wired with 6mm T&E. I was thinking of fitting a 25A MCB, using heat resistant 2.5mm cable for the hob, and 4mm T&E for the oven due to the longer run, terminating with a heat resistant sleeve. Does that sound OK? And according to the current regs is replacing a not like for like MCB in the CU notifiable work, and even if it isn't must it still be carried out by a fully qualified sparks? If so then I will happily pay someone to do the work. Thanks. [/QUOTE]
