Here is the acceptable way to get 115v if you do NOT need 230v


Remove the white wire from the circuit breaker and connect it to the
panel neutral.


At your outlet, the white wire will be the 115v return
and the black wire the 115v "hot" .

The sheath should of course be ground.


This will work fine but assumes there is no 230v device anywhere that
was using the wiring.



Yeah. I think that would be simplest too.
