At the outset, may I beg forgiveness for my ignernz, but I would like to
contribute MY 2ยข worth to Bill: I have "done this" several times, and it
seems perfectly OK to shield "all four in a cable". I think the concept of
shielding "individual pairs" is for commo circuitry, not power-stuff like
this. Besides, when shielding a motor's wiring, you are "shielding EMI IN,
not OUT"! Control lines separately shielded and separated; sounds like you
know whatcha doin. JRR
