Cooker wiring
We're thinking of getting a new range cooker (all electric). Currently
theres a 30 amp (possibly 35 amp) cable into the kitchen and the 32 amp ring main. I know that for a seperate oven and hob usually the hob is wired to the cooker cable through an isolation switch and often the ovens to the ring main through a 16 amp plug or simular. What happens with these large range cookers, I added the power comsumption on one and it came to a total of 67 A if all things where switched on. Would that need a new cable to the consumer unit or does it take power from both the cooker spur and the ring main? Also what happens in a normal house with single phase electrics, if your cooking a large lunch and some decides to have a shower with a 10kw shower (40 amps) thats goign to max out the 80 amp trip and the 100 amp consumer fuse. Presumable the trip just cuts the power on overload. Must cause a problem or are most modern houses that use electric for cooking 3 phase these days. Its practically impossible to run a new cable back to the consumer unit, so I am wondering how this limits our choice of cooker. Thanks Jaime |
