I am looking at the connector model in MIL-HDBK-217F Notice 2. I am confused about when to use the Connectors, General model in Section 15.1, and when to use the Connections model in Section 17.1. For example, for a 30-pin crimped rectangular connector, would I use the 15.1 model for a rectangular connector, or would I use the 17.1 model for a crimped connection (x 30), or would I take the sum of the two?
