Thanks a lot Matt.
Larry, we just started using the Wago's and love them. Hadn't thought about them for this and assumed they would not work well with solid Cat 5. Seems like the Cat 5 would want to break but you are right and they will work with solid wire. Have you used them this way? I'm going to try it today. The ones we use have no goop in them (that I've ever noticed) but otherwise look identical. However, unless you know something I don't they are Not insualtion displacement and the web site also shows the wire stripped back when inserted.
