<br>
Before the code change the Hi-leg was commonly on the Right in my region. <br>
A, B, C is clockwise rotation. But nothing said it would ever be
checked, the utility usually does not say, and after it is connected and
energized you test at the last disconnect before the motor. <br>
<br>
(on a job in 1992 where I had connected several motors including a
200HP, overnight someone had reversed phases to my Main panel board. I
tested before closing the MCC and found with my phase rotation meter the
problem, the 200 HP could not be run or even bumped without damage,
always check your rotation) <br><br>--- On <b>Mon, 8/23/10, Darryl
