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 Switch box and connect
to one terminal.
Connect another Phase wire to the remaining terminal
of the switch and draw it to the Ceiling Rose position
and connect to one of the 3 terminals of the Ceiling rose.
Connect the Neutral [N] wire to the Neutral Link provided
in the DB.
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.
