The existing cooker circuit is 6mm² on a B40. The customer wants to replace the free-standing cooker with 2 built-in ovens and an induction hob. Will each cable from cooker outlet to device need to be the full 6mm², (e.g HO7RN-F) or can I get away with anything smaller and more convenient (e.g. what's supplied with each oven/hob, if anything)? The final purchasing choice hasn't been made yet, so I don't know whether any of the devices will be suitable for a 13A plug/FCU, which can obviously accept a smaller cable.
Mike, I don't really get your point about bare-E T&E. Surely in UK-style T&E, the bare E is (on the long axis anyway) touching or almost touching both the L and N's insulation. So there is only a single thickness of insulation between L+E that needs to gets charred before a L-E short circuit develops. Whereas the Irish/NZ full fat T&E will have at least two thicknesses of insulation between L+E. So they should in fact be more robust against transient overheating than the UK and thus less needful than the UK of having a full-size cpc ???
Irish T&E to I.S. 201 does have a full-sized cpc though.
