Well, supposing I'm running a space heater (15 amps) on the black wire and

That's 1A in the neutral if they're on opposite phases. However, how
are you going to make sure noone ever moves a breaker wrong, butting

I guess you figured out that last word was supposed to be "putting".
Spelling checkers can do bad stuff like that.

them on the same phase and making it 29A?


How would you wire it differently?

With two hots and one neutral, you'd be possible to overheat the neutral in

Not if they're connected properly.

Any feeder or branch circuit that supplies loads that are connected to
two or three ungrounded conductors must be protected by common trip
breakers or breakers equipped with listed handle ties. To disarrange
the circuit you would have to move at least one of the conductors to a
different breaker rather than just moving the breaker and that isn't
very likely.

That's what I wanted to know. I have a shared neutral circuit in my
house that's working OK now (different phases). I need to fix the
breakers.
