This is a pretty interesting table, especially in light of the sizing of PowerPole connectors. The "30A" contact doesn't comfortably fit anything larger than 12g wire. I don't have a "15A" contact handy, but my memory is that it handles 18g OK, but I'm not sure if it will handle 16g. That's just ... broken :-) > If it were me, I would buy the connector from Elecraft. Yeah, I guess I'm going to have to get a few. I admit that my bench is littered with little cords that have "15A" PowerPoles on one end and generic power connectors on the other end, all made out of 20g or 22g zip cord. I'm having a really hard time imagining pushing 16g zip cord into the body of a 2.1mm plug! I think I've done this with 18g once, and it wasn't pretty - perhaps the cable sold by the Wireman has thinner insulation? 73 de chris K6DBG _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
