While several people have pointed out you should never use a safety

implying he has both available.

Or he may simply be unaware that 240V circuits don't have a neutral, leading
him to think he has one when he really doesn't.

It's time to throw all their damned tea in the harbor again.


Being a 240V line to a pool pump, this raises another issue. Where
is the GFCI? If it's in the panel, then he needs one that will
accomodate both 240V and drawing 120V on the same circuit. Some GFCI
are strictly 240V and if you unbalance it by drawing 120V from one leg
to neutral, it will trip.
