We hardly ever use our oven. And when we do it is for pizza or something like that and I am not in the shop when that happens, just my wife and I in our house. We have a separate cook top, which is used 99% of the time and is on a totally separate circuit.
Here is the part that will have some people freaking out. You know where I am going with this. I plan to wire from the J box to the new planer. The cables into and out of the j-box are both 4 wire. Black, red, white, and green. The new planer diagram shows (in) as a black, white, and green. So I am 95% sure that the correct thing to do is black to black, red (into j-box) to white (out to planer) and green to green. The white on the incoming feed is not needed for the planer or the stove. According to the product data for the oven, the white is only needed in some jurisdictions, which tell me its not all that important. If I understand this correctly the cable from the J box to the planer could be 12 gauge 3 wire.
So, are my assumptions correct and is there any reason why I should not do this?
The only thing keeping me from running a new cable / breaker is the cost. I can do it, but why?
Thanks for your help
