Wiring a Oven
Electrical Question: I have removed an old wall oven and am installing a new one.
- The wiring coming through the bottom of the cabinet has no visible junction box.
- I am not sure about the ground wire.
- Right now I have black to black, red to red, white to white with ground tied into it, but I do not have a junction box to connect ground wire with.
I am not sure what to do.
