Last month we told you about future subjects we plan to cover on our blog, like: electric vehicle charging stations, software for designers in medium voltage ... asking you to tell the ones you are interested in or would be ready to contribute to. Your first feedbacks show particular interest in the following ones:

  • Short-circuits and their actual effects on people and installation
  • Load-shedding
  • Earthing schemes and earth leakage protection

  • We are already discussing with some electrical engineers to cover these subjects and bring you content and debates in the near future.

    Before we go deeper on the short-circuits subject in particular, we would like to ask you one quick question:

    Have you ever been in a situation where a short-circuit occured, involving equipment damages and/or people being injured?

    > yes
    > no

    Don't hesitate to share your experience about it on the linked forum topic.

    Panel builders are all cheaters?

    I am a young professional in charge of electrical maintenance and new works of a Lime production site in Belgium.

    From time to time I subcontract the renovation of electrical control panels to panel builders. Frankly speaking, I find the bill amount is going up and up! When asked why, my panel builder gives straightforward answer like ”Sir, have you seen the price increase of copper these days? The price of the cables has doubled in recent months, moreover, all materials costs have increased!"

    Similarly, I often hear that his workers are not happy with peanuts, and that social charges and taxes are also increasing, blah, blah, blah…

    But I discovered recently that there are solutions on the market to make panels quicker to assemble, and thus cheaper than the ones I pay for, I’m pretty sure.
