Regards to all,
I am electrical engineer from Croatia. I have expirience to work with small free software like Schneider Ecodial, Chez OEZ and of course with great ABB DOCWin ver 2.0.
For design electrical network in industry, building and even in distribution (i think this whose primary goal of ABB developers) DOCWin is the best of above.
All software are familiar with EN, IEC, CIE but not with British Standard or NEC.
Summarize: i recomended DOCWin and then ECODial, OEZ is very unskilled.
