I have a few of these connectors that I got off a construction site. These were used as temporary electrical connectors on the site until they were torn down when the site reached completion stage. They just dumped a whole lot of cable along with the connectors in a big dump and yours truly saved them. How I have a whole plastic container of these that I kept in my junk pile. These little connectors can handle 16A with no issues, and the connectors I found can handle cable cores of up to 2.5 mm. At the present moment, I am thinking of deploying them on the speaker cables of my Stagepas 500 sound system…so I can easily detach them or connect them when required. These are good electrical connectors to have in your toolbox.
