Method of Wiring -Residential
Make sure that the Power is isolated [ shut down] to
the Distribution board or any circuit you will be working
Connect the Phase [L] wire to the outgoing side of a
6A or a 10A [Maximum] MCB from the Distribution Board
[DB]. Draw the Phase wire to the nearest Switch box and
connect to the common terminal of the first Two way switch.
Connect two separate phase wires to the remaining terminals
of the first 2 Way switch and draw them to the other Switch
box position and connect to two separate terminals of
the second 2 Way switch.
Connect the common terminal of the second 2 Way switch
to a Phase wire and draw that wire to the Ceiling rose.
Now connect a Neutral [N] wire to the Neutral Link provided
in the DB and draw it to the Ceiling rose.
It is good practice to number the Phase and the Neutral
wires at the DB for easy identification as one circuit.
Connect the Earth [E] wire to the Earth link provided
in the Distribution Board. Draw these Neutral and Earth
wires directly to the ceiling rose and use the two spare
terminals to connect these wires separately. Now all the
3 terminals of the Ceiling rose are connected.
Take the lamp holder and a short length of 3 core flexible
cable and connect the Phase and Neutral wires to the holder.
If the holder is a pin type one , then either the Phase
or the Neutral can be connected to any terminal. If the
holder is Screw type, then the Neutral should be connected
to the threaded part of the terminal and the Phase to
the other terminal. Normally the Earth wire is used for
a Lamp fitting with metal parts to be connected.
Then connect the Phase, Neutral and Earth wires of the
flexible wire of the Lamp holder to the Ceiling rose to
correspond to the L,N and E respectively.
