Definition standby power vs emergency power
Is there a clear definition of the difference between standby power, which would not include life safety, and emergency power which would include life safety? Do both include life safety?
Where in the NEC 2005 would I look?
No both do not include life safety. emergency power and it's descriptive definition are found in Article 700.
As for the generic term ' stand-by power ' generally refers to systems designed to aid emergency personnel in the event of fire or catastrofic event when normal utility power is interrupted but not intended for life safety. An example would be Article 701 "legally required standby-systems."
Thank You for your response.
Lighting would be life safety, unquestionably, a fire pump or elevator would be also if determined by the local authority, or NFPA is that correct?
If I have a branch circuit to an emergency lighting panel, and found that the extra slots were being used for UPSs by IT people, would that be a violation of NEC 5000, 700.15?
Last question, It seems to be a standard that generators should only be loaded to 80% of thier full load capacity. Where do I find the code that would stipulate that?
