Method of Wiring -Ring Circuits
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
32A MCB from the Distribution Board [DB]. Draw the Phase
wire to the socket outlet box and connect to terminal
marked as L [Line] of the nearest 13A receptacle.
Connect the Neutral [N] wire to the Neutral Link provided
in the DB and draw the wire to the nearest 13A receptacle
and connect to the terminal marked as N [Neutral].
Connect the Earth [E] wire to the Earth link provided
in the Distribution Board. Draw Earth wire to the nearest
receptacle and connect to the terminal marked as E [Earth].
Now we have all three wires L,N,E from the Distribution
Board connected to the first receptacle .
From the same socket outlet, take another set of 3 wires
from L,N,E and connect to the second socket outlet.
From the second socket outlet, take another set of 3
wires from L,N,E and connect to the third socket outlet.
Proceed like this until you come to the last 13A socket
outlet. From this last socket outlet take the 3 wires
L,N,E and draw up to the Distribution Board again and
connect Line [L] to the same 32A MCB. N to the same neutral
link and Earth to the earth link.
From each 13A socket outlet, you can wire for another
13A socket outlet, which is called a "Spur".
It is good practice to number the Phase and the Neutral
wires at the DB for easy identification as one circuit.
