Greetings members.
Can someone point me to the “basic” standard that would be the foundation for household circuit breaker trip curves? 120V (North America) and 230V (Internationally) specifically. I saw on one curve the NEMA AB-2 which does not exist on the NEMA site. Typical abnormals in UL standards are done at the points listed below which seems to indicate where the curve would need to safely reside. 110% - 7 hours 135% - 1 hour 200% - 2 minutes. Can one of you fine people refer me to where the requirement(s) would come from? NEMA, IEC, NEC LMNOP?
