Thanks to all for the kindly advice. I've turned the project over to
an electrician and will soon be circuit-overload free (I hope). I'm
sure my ignorance of this subject was clear to all. I'm at least able
to discuss the topic with the electrician now.

I was surprised by Jack's remark about my question on this subject
"straining" the old adage about "no such thing as a dumb question,"
and am wondering if maybe he's the "dumb-question designator" for the
forum? If so, he's doing a heckuva job. Of course, isn't this exactly
the place for ignoramuses like me to ask questions about home repair,
even dumb ones? If I knew the topic sufficiently, what's the point in
asking the questions?

Thanks again for the assistance.
