BobDee Posted June 8, 2009 Share Posted June 8, 2009 We are in the process of getting a new kitchen into our 25 year old house.Currently we have a 32 amp feed for the existing cooker and a tee off of this that feeds the electric ignition system for a gas hob. The new kitchen supplier says the gas hob needs a 32 amp feed of its own to comply with latest norms even though the electricity drawn is microwatts for just the igniter circuit. His argument is that some person in the future might replace the gas hob with a four ring induction hob drawing megawatts. Installing another 32 amp feed back to the tableau is a major job with much upset to the decor etc. All the existing installation is as far as I can see perfectly safe and conformed fully at the time of installation in the 1980's. So questions:Does a gas hob upgrade with just an electrical igniter circuit really need a 32A feed?The new regs appear to say a dedicated 20A circuit is OK for an oven. Is this right?Given this is a change of appliances in an older house and not a new build, what is the position regarding conformance to the latest electrical norms?BobD Link to comment Share on other sites More sharing options...
Nick Trollope Posted June 8, 2009 Share Posted June 8, 2009 Your 32A supply is as it exists, to currents "regs". In theory, the gas hob should have a lower current supply (certainly not 32A), it is not mandatory. My preferred option would be to install a 16A socket for the igniter from a power circuit.There is no requirement for 2 32A supplies in a domestic kitchen.A 20A supply is acceptable if an oven (only) is fitted, but not for a hob+oven or a cooker. Your 32A supply is fine for an oven.Your installation must be safe. There is no requirement for it to conform to the latest regs (unless you change something, when it must).

Northender Posted June 8, 2009 Share Posted June 8, 2009 Why not remove the tee and get yourself one of those Piezo portable ignitors. Link to comment Share on other sites More sharing options...
BobDee Posted June 9, 2009 Author Share Posted June 9, 2009 Thanks for the replies folks. Nick, if an oven, (Free standing device with traditional type oven below with hot plates on top) is OK on a 32A feed, would not a hob plus insert type oven amount tp the same thing?Also what do you mean by "change anything"? Would upgrading appliances constitute a change?RegsBobD Link to comment Share on other sites More sharing options...
Théière Posted June 9, 2009 Share Posted June 9, 2009 Hi BobDMy twopenny worth,Your electrician says someone in the future may want............Then let them pay for it at that point, not you now, how on earth can mystic meg the electrician know what the future requirements will be and what the regs at some point in the future may say.
