Question: How are you supposed to connect wire to the Australian outlets and switches shown above? Those connection cups with the set screws look rather big to just hold a single 14 or 12 AWG wire.


The wire is simply folded back on itself to double up the thickness. In many instances, particularly for power points more than one wire is connected to each terminal. In this case, the wires are simply twisted together before insertion.
These types of terminals are very accommodating for different wire sizes and number of wires connected.
