`The connectors in Larry's post 18 are Scotchlocks and I don't know if they were designed for stranded wire. The "dolphin" connectors are known as B connectors, come with and without goop, and are called "good and plenties" bu phone men(which I still consider myself to be on occasion. The Scotchlocks are a lot more costly than B connectors. The b connectors are supposed to be pressed flat and I never use the goopy ones. Those Wagos look nice though.
