220 Volts has a higher kill rate than 120 Volts, I have two large 240 Volt
(3 wire) room heaters
and all 3 bedrooms have a 240 Volt outlet, (added since build) so we can use
both here.

agree, must have been a
dim bulb from the 'phone company. (their color code has 12 colors instead of
10) I still don't get
that one.
