I am replacing an old electric range and have some wiring questions.
Th eold electric range was hard wired to the electric box. The box
had 3 wires (Red / White / Black). The ground was connected to a
screw on the side of the stove and connected to a copper pipe.

1. I need to put in a plug so I can can plug in the new range. What
kind of plug do I put in? A 3 prong range plug since I only have 3
wires?

2. How do I ground the new stove? The same way the old on was?

Any help would be greatly appreciated.

Thanks,
Jay
