Wiring a stove
I am trying to figure out the correct way to wire a stove and need some help determining which wire I can use.
I had both a double oven and a stove top on separate circuits. I replacing them with a single stove and I am not sure which set of wires I can use.
I am located in the U.S. so please make responses for U.S. codes and regulations.
Double oven was directly connected with three wires a red, black and white. The breaker is 45 amps (double breaker?? it is two breakers put together) The wires are really thick so I am sure this is a 240 line.
The stovetop was directly connected with only two wires one black and the other white. The breaker is 40 amps (This is also a double breaker) I am not sure if this line is a 120 or 240.
The oven I have says the electrical supply it takes is 120/240 VAC, 120/208 VAC. I do not know what this means in terms of which line I can use.
I am installing junction boxes to extend the wires that I need (stove is in a new area of the kitchen) and I want to make sure I use the correct wire.
My questions are:
Can I use either of these lines for the stove?
If not which one should I use?
What is the correct size wire to use to extend the existing wiring?
What should I do with the extra connection that will be left from the wires I do not use?
I want to install a plug for the stove what is the correct size outlet to use a 30amp or 50amp?
How high off the floor should I put the outlet? I want to make sure the stove will slide back against the wall.
Also should I use a surface mounted outlet or put it in the wall. which is better?
Thanks for the help.
