New Oven Installation

I am not certain how to connect the new oven I purchased. My existing home wiring (in my older home) has black, white and copper wires. The black and white wires are large guage wires. The instructions for a 3-wire installation tell me to connect:
black (oven) to black (house)
red (oven) to red (house)
white & copper (oven) to white or grey (house)

My problem is that my house wiring does not have a white or grey wire - it has black & white large gauge wires and a copper wire.

My first guess is that I should connect the:
black (oven) to black (house)
red (oven) to white (house)
copper (oven) & white(oven) to copper (house)

I would appreciate advice from those more knowledgeable than me.

That is the only way to make the connection. However, it is NOT safe. You need to replace the wiring from the panel to the oven with new wiring.

It sounds like you have 2 conductor with ground type NM cable feeding the oven.

This is not allowed.

In this (2 wire) installation, the ground wire is a circuit conductor and actually conducts power.
A un-insulated conductor is not safe and can cause a fire.
It needs to be replaced with a (required) 3 wire plus ground feeder.
You need a electrician.
