Cook top with wall oven under wiring
I am considering replacing an electric range with a 30" cooktop and 30 inch wall oven. The range currently has a 40A 240v breaker. The kw's for the cooktop and oven are 8.4 and 4.1 respectively. Using info from Table 220.55 of the NEC - circuit for a 15kw range would need to be rated at 8kw plus 5% added for each kw over 12.
In my case this comes to 8.04kw. 8040w divided by 240v equals about 34A. Since the circuit needs to be sized at 125% for a continuous load I come up with 42.5A. This being said do I need to increase the size of my breaker to 50A? |

Check out some similar questions!
My old electric cooktop and a separate wall oven were attached together to a single range cord connected to a 40 amp outlet ; is this OK? If it is not how can I do it?
I am replacing an electric cooktop with a gas cooktop. The electric cooktop is wired to a 30 amp breaker. The gas cook-top needs a 15 amp breaker. Do I need to pull the 30 amp service and run a new line from a new 15amp breaker? There is plenty of room in the panel to do this.
If I have white, red black and copper wires coming from the wall and the wall oven do I wire each wire separately each color to each color?
Well I've spent several months reading responses to questions on here before deciding it was time to post a question of my own. Tkrussel, you should know that your no-nonsense direction and input has been very helpful to me during the last few months as I have been rewiring a cabin I purchased...
