Like Steven, I am encountering a 3-wire house source consisting of 2 hots and a bare ground wire in Romex sheathing. It is a dedicated circuit. The house was built in 1978. The 46-year-old GE single oven I just removed has 4 wires. The white neutral and the bare ground wire from the oven were clamped together and attached to the bare ground wire from the house source. The plate on the front of the oven says "120/240 volts". This oven, wired this way, has operated without incident for 46 years. I have looked at the installation instructions for new GE, Frigidaire, and Whirlpool ovens. They all have 3-wire installation instructions based on 2 hots and a neutral, not 2 hots and a ground. Is it safe for me to wire a new oven in the same manner that this old oven was wired? Thank you.
