Can any of you designers out there tell me how you go about sizing the conductor from the Star point of the transformer to earth?
By this i mean if there was a HV earth electrode around a 1000kVA transformer made up of 2 X 70mm bare copper conductors onto a common earth bare this would give a...
Does anyone know how to correctly size the earthing conductor from the star point of a 11kV/433V distribution transformer to ground for its reference. I believe that I can use the maximum single phase to earth fault current and then give it a 1sec/3sec withstand time depending on client, Is this...
I have been asked once or twice if I would fit an extra TV aerial point and I have always declined as this is not something I understand in depth so therefore dont want to do it.

Looks like the government are fiddling again. Funding for domestic EV charging points, which should carry on until March 2015, may be pulled as soon as TWO WEEKS time. These people have absolutely zero idea of how a SME works. The domestic EV charging point scheme has attracted praise and...

I’m currently doing a job where I have to replace 20 MCB’s with RCBO’s in the main consumer unit of a public building. I was told by another colleague, that you only had to trip test one RCBO and to use this figure for the remaining 19?
