Replaced our electric range with a new one, and the wiring required to make it work looks wrong to me. @Jerzsubbie provided me with a nice picture I'll include there to explain what's working and why I question it.
For any 4 wire 240v thing I've ever wired, there are red (hot), black (hot), white (neutral), green (ground). With a meter you can test 120v from red to white and black to white, and going red to black gets you your 240v.
Inside the stove you've got connections like this:
Our house is from the early 80s, but has a 4 wire plug for the stove. When you connect it per the 4 wire instructions it doesn't work (which is how the installers did it). We looked at the old stove which also had a 4 wire plug but inside found that white and green were tied together. It's been that way for 6+ years since we moved in. Wiring the new stove that way with green/white tied and it works.
That just seems wrong to me, it's like the neutral doesn't go anywhere and you're completing the circuit over the ground wire? Maybe it works because there is nothing else on the circuit except the stove so there is no way anything else is going to pick up a huge voltage off the ground? Or maybe the house is an electrical fire waiting to happen?
They make a 14-50p to 10-50r adapter (popular with Tesla owners it appears) so what's the pinout on that? Are they just tying white and green together inside?
