WebFeb 29, 2024 · Feb 28, 2024. #8. Carultch said: The short answer for the definition of load diversity, is the fact that not all loads will run full capacity at once. Some will run now, some will run later. And even if they all run at the same time, some of them might be running at less than their full load value. OK, this explains that the loads can be diverse. WebLoad Factor 3. Diversity (yep, I’m dropping the word ‘factor’) A & B motors . Mode 24 It is customary to classify all electrical loads as either Continuous, Intermittent or Standby mode.
