All so -- but I might also mention switching transients and unsuppressed high frequencies; I daresay semiconductor-switched phases could be a problem. Cortland -Original Message- >From: "Wiseman, Joshua" >Sent: Jun 29, 2020 8:17 AM >To: Cortland Richmond , "EMC-PSTC@LISTSERV.IEEE.ORG"

You bet!  I've done it many times.  It's not perfect, but does give you a rough estimate.  The only requirement is being able to butcher the power cord so you can get tat the individual conductors.  Putting both through the clamp gives you the CM. Then take either L or N and twist it 180
