I am trying to connect a new 4-wire range in a new location in my house. When I removed the old cover I see 3-wires connected 1) red 2) black, and 3) green.
If I understand correctly, red and black are 110v each, and green is ground. I picture a rod in the ground for green. Neutral in another hand, I picture it as a wire taking back electrons to the station.
Now when I open the panel - I noticed that the neutral (white) and the ground (green) are connected to the same bar on both sides of the panel.
So my questions are as follows:
-- Why are white and copper (ground) come from the same bar?
-- How do I use this setup to connect a 4-wire system?
Side note: My new range allows for a 3-wire setup - maybe all is possible with my house.
