Hello,

When developing a model in order to run short circuit analyses, is it recommended to group LV motors <50HP? Upon looking at IEEE 399 and IEEE 551, this appears to be typical. Are individuals utilizing this technique or modeling all LV motors individually?

Thanks for the input.

I would use the red book as your go-to source, along w/ the purple/violet book. Per the red book, small motors are lumped into one "motor source" from a modelling perspective.
