Wiring for electric range
I am trying to install an electric range/stove. The house was built in '85, and the range was directly connected to the wiring. The cable is labeled "6-2 0 NON METALLIC SHEATHED CABLE TYPE NM 600V E10816K (UL)." The cable has 3 wires: a white braided copper, a black braided copper, and a single copper wire.
1. Could someone explain what the three wires are?
In addition, the stove came with a new power cord that has four wires.
2. Can this plug be used?
3. If so, what will the wiring for the 4 prong receptacle be since the cord from the wall is only 3 wires?
4. If not, is it safe/legal to install a 3 wire power cord and a 3 prong receptacle?
