DIFFERENT WIRE CONNECTORS

[Enigma]

One of our electrical guys was just showing me these "wago" connectors they are using:

Looked interesting, I know I was cursing a few nights ago when I needed 3 hands trying to hold up a heavy light fixture and trying to thread 3 wires on a marrete.

Push in connectors are great and have been around for a while. Most of them are reusable, some easier than others. I've often used these:

Because of the pressure they apply on the wire they are usually not good on small/fine strand cables but work great on solid core and thick strand conductors.
Getting these ones off is usually a bit of a pain.
