    You mentioned later that you're using a clamp meter. Quick question - did you position this around a single core of the supply. or the 3-core mains cable? If the latter, is your clamp meter designed for 2/3 core cables?, or a basic clamp meter? If the latter, then your reading is inaccurate.

    It's a clamp meter designed to be placed around a single core, for example either the live or the neutral, and used as such. I have various dial ammeters that I could also have used, but for a quick cursory look, the clamp meter was more convenient.

    Puerile as puerile goes. But whatever:)

    No mention of Drive, VFD or Inverter Drive?
    You think that's too expensive? You're not a Model Engineer are you? :D

    That's quite obviously utter bunkum, otherwise nothing electrical other than simple resistive load systems in industry could ever be built to a specification without years of iterative testing, fettling and re-testing.

    0/10 seems extremely apt as it happens ;-)

    You're saying that something calculated every day by professional engineers cannot be calculated - you're full of it and don't like that you are demonstrably incorrect, I suggest you get used to it as you seem hell bent on continuing the pattern :D

    Hmmm, you are waffling and sidetracking and you know it, you know very well what I was referring to. This silly point scoring and displays of bravado don't do you any favours. It makes you look bad.

    I suggest you apply your energy and knowledge (which I'm sure you have in abundance) to better use, as practically all the other knowledgeable posters do, to whom I am grateful.

    End of story, I let you have your last word, because of course, you must.
