Selective Coordination
Selective Coordination
(OP)
It has been my understanding that when you do a coordination study you are not allowed to overlap OCPD. I have a few cases where the CB does not overlap but the curves are right next to each other. Is that considered overlap?

marks1080 - 400mS may be a comfortable margin for lower current ranges, but will probably be impractical many cases in the short time ranges.
