Thanks for the info and the quick response. But what I am looking for is:
If I am to sell both double busbar (dbb) panels and single busbar (sbb) panels to a utility company - for which application would they prefer to have a dbb panel and not a sbb panel? Ofcourse they wouldn't want to...
Please can anyone tell me where it is preferable to have double bus bar over single busbar switchgear panels in power distribution? How does the double bus bar sytem work?
