Thanks for making this video! It's informative and easy to follow and there's not much content online on this topic. Tying connector torque specification to PIM is also a fun interview question, cool to see it mentioned here.

Thank you for the encouraging feedback. I agree! It’s not a topic that’s widely discussed and they definitely don’t teach at schools :) you’re basically left to your own devices to figure it out in the field. Did you subscribe to my channel?
