Yearssssssss ago some appliances like say stoves that had 240 volt heating elements and 120 volt clocks used a single wire for BOTH the Neutral and Equipment GroundING conductor.. NO MORE
Good advice below, here are my inputs so hopefully you can understand this in detail...
To run 240 volt you need the two Hot Phase Conductors (often black and red) L1 & L2 which are 240 volts PLUS THE SAFETY EQUIPMENT GROUNDING CONDUCTOR (often green or bare)
To run 120 volt you only need one Hot Phase Conductor (say L1),,,,The Neutral (often White),,,,,an Equipment GroundING conductor (Often Geeen or bare)
To run BOTH 120 and 240 volt, there needs to be 4 wires,,,,,,,2 Hots (L1 & L2 Black & Red), 1 Neutral (White), 1 Safety Equipment Ground (Green or bare)
On a typical 120/240 Volt Single Phase 3 Wire home distribution system its 240 volts Line to Line but only 1/2 that or 120 volts from EITHER phase wire to Neutral
DO NOT USE THE SAFETY EQUIPMENT GROUNDING CONDUCTOR TO CARRY NORMAL NEUTRAL RETURN CURRENT,,,,,,,,USE THE NEUTRAL (a groundED) conductor for that. The Safety Equipment GroundING conductor is to carry FAULT CURRNT ONLY
The Neutral (groundED conductor) and Equipment groundING conductor are bonded ONLY at the main service entrance panel NOT MORE DOWNSTREAM
The thing is since BOTH the Neutral and Equipment GroundING conductor are bonded at the main panel an appliance will work if those got substituted or used for each other etc BUT THAT CAN CREAT A DANGER AND IS NOTTTTTTTTTTTTTTT ALLOWED
Hope this helps, over on Johnnypopper a couple years ago I wrote a long article trying to explain all this, I will have to find it and post here sometime
Keep safe, best wishes n God Bless

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer.
