I am trying to find more information on emergency power systems in public buildings. Is there a definitive source of information out there that I am missing? A Guide, code of practice, regulations, etc.
Depends how seamless you require it to be. Is it a case of the protected areas must run at all times so that if the power does drop the ups takes over until the generator comes in which may be 2 mins later to take the load off the ups which are more of a short term solution. Or if it doesn't really matter if it drops for 2 mins and then the genny takes over. It'll depend on what the public building does.
