What is the wiring diagram for a light switch in Australia or New Zealand?

Answer 1

In Australia we use 1.5mm2 TPS cable for lighting circuits. The colours for fixed wiring are red - active, black- neutral and green/yellow for earth, also white is used for switch wires. All luminaires and lighting points must have an earth at their location. The process for a simple lighting circuit for looping at the switch method (feed starts at the switch) - one switch and one light point is:

The feed (active) goes to the common point on the rocker switch and the neutral goes to the loop terminal on the rocker switch. The earth is connected to a two screw connector separate from the switch. A switch wire is then connected from terminal 1 of the rocker switch to one of the main terminals (these are the terminals across which the lamp terminals are connected) on the batten holder ( this is the fitting which holds the lamp). The other main terminal on the batten holder is connected to the loop terminal on the rocker switch with the neutral. The earth conductor is connected from the two screw terminal at the switch position to the earth terminal in the batten holder.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.
