My new PIR light for my garden/yard arrived today but i was wondering how Wago connectors work within a junction box? The box is waterproof of course, but i only know how a terminal works. Can someone explain how you use them with wires? As i've got no idea. An electrician told my dad who bought the box they are used all the time for those kinds of lights. But someone will have to explain it to me if that's ok?. Thanks.
