    Do you have calculation for auto transformer winding sizing (reduced voltage motor starter)
    thank you.

    Can you have temperature rise simulation software for panels?

    Jan 26, 2015

    Thank you very much for your most informative news.
    My problem is, the home electrical bill/energy consumption/electrical load calculator did not work better for me.
    Eg. I worked out the load current / power consumed by 10 x CFL bulbs 15W and got 470.68 A / 150kW (according to the calculator), and thus compelled me to install 600A Incoming ELCB in my residence?
    Please take a look and advice.
