Try this color combination . . . .
Black wire = copper colored screw (narrower blade)
White wire = silver colored screw (wider blade)
Green wire = Green screw (rounded blade)

So when I lop off the 15A 115V plug - I suppose I'll see three wires.
Black, n' white, n' green.
When I attach the NEMA 6-20P plug, he said redundantly, does the black
need to go to one particular blade, or can I choose thanks to the magic of
Alternating Current.


I ask 'cuz thanks to the magic of the internet, I learned a few years ago
that there was a right way to wire zip cord in a lamp with a polarized
plug...
