Default 220 volt to 110 volt

Most. :-)

offering excellent, intelligent, and clearly safety concise
advice.

As pointed out, the 240 volt - 3 wire (no common, just ground) is what
I have.


Caesar Romano, I'll be waiting for your apology any time you're ready. It's
just as I said: I didn't misread anything. You did.

Common I would assume, is the alternating current line of one
of the hots when not sending current, thus switching back and forth.


That is not correct. The two wires have a potential of 240V between them, and
EACH has a potential of 120V to ground. Neither one is "common".

This I do remember from my basic EE courses.


*Electronics* engineering, I presume, not electrical -- or else you don't
remember as much as you think you do. :-)

My dilemma, the 240 volt pump circuit is approximately 200 feet from
the electrical panel buried beneath a cement slab, thus pulling a new
120 volt line was not an option.

Therefore, the suggestion of either using 240 volt lights, a 240 volt
to 120 volt transformer, or which no one suggested, SOLAR lighting may
be my only options. If I choose one of the first two, I will take
everyone's suggestion and hire a licensed electrician!


Did you notice gfretwell's suggestion that it may be possible to rewire the
motor as 120V? If that's possible, that would solve your problem easily.

I must say, usenet groups are very helpful in understanding options
and again I thank you all for first, qualifying that safety is the
most important criteria, and cost the second.


Glad I could help...
