Oven Installation - Three prong outlet
Just an update and answer for anyone that comes across this looking for help. I turned off the breaker to the outlet, removed the outlet cover, removed the outlet hardware so there were just three wires (two hot, one ground). I added a junction box and wired the oven directly. As per the instructions with the oven, neutral and ground went to ground and one hot wire to each of the hot wires. Done and done, super simple.
