How to connect a 4-wire range from this panel?
This is your main panel so grounds and neutrals are allowed to be attached to the same bars.
You'll need a four wire whip, probably provided, from you new range, to your outlet box. Connect your black to black, red to red, white to white and green to bare copper. The black and the white wires should be 120 Volts phase to neutral and 240 Volts phase to phase.
Check your instruction booklet and it will tell you how to remove any jumper from neutral to ground on your range.
Make sure your range amperage does not exceed the breaker and wires that are feeding your range circuit.
If your range didn't come with a 4 wire whip, you might be able o add the white wire depending on the FMC size.
