so in this presentation I'm trying to help you with the connections in a standard three plate
looping method which is commonly used in domestic dwellings so this ceiling rose pendant or batten
lamp holder has been opened out to expose the terminations let's look at those terminations
first the far left hand side as a block of three which is identified with an N and that's for
neutral within the ceiling rose itself the center block of three is identified with the word loop
and has the permanent line connections coming in and out of it and the far right hand side is
usually identified with the letter L but is actually a switching line conductor they're
the ones are one that can give you control over the lamp by turning it on and off if we look at
the top two cables both left and right hand side they are the supply coming in and the
supply going out for this I will suggest the left hand side is the supply coming in and the right
takes the supply into another room so if the supply comes in on the left hand side it will
bring in a permanent neutral connection which is terminated within the neutral block it will bring
in a permanently connected line conductor which is connected into the loop terminal in the center
and to bring in a circuit protective conductor terminated into the earth connection within
the ceiling rose itself we can now see that the bottom right hand cable is the one simulated to
a switch drop if we see that the switches say a one-way switch we can see how the switching
conductor goes to the switch and returns we take a permanent line from the looping terminal in the
center and goes down to the one-way switch and is commonly connected into the common terminal
we have a switching line conductor returning in this case they've used twin and CPC cables and
the conductor is blue but identified both ends with brown sleaving because it is it a neutral
it's a returning switching line conductor and is terminated in the L terminal which really is for
switching line so you have control over the lamp the CPC once again is terminated in the earth
terminal within the ceiling rose itself it can be easily altered this switch drop now to a two
way or two way intermediate switching the cable which we've shown here for the switch dropped
for a one-way switch would be identical going down if it was a two way so with the two ways switching
configuration the drop to the first switch still is in twin and CPC or twin Brown we showed twin
and CPC cables here but the terminations will now not be in common and L1 the terminations
coming down will come down into L1 and L2 leaving the common terminal without a connection at the
moment we introduced a three core and CPC cable which links together L1 L2 and common of the
first two way switch across to L1 L2 and common of the second two way switch it will not matter
which colours are used in which positions however in my college I like to use black as common this
drawing shows brown is common and it doesn't matter if your L1 and L2 in the first switch
are in L2 and L1 the opposite way around in the other as long as the common cable remains the
same so if you've chosen to use brown common in the three core cable it must be positioned in the
common terminal of the second two way switch in order for it to function correctly the cable in
the top right now goes into say another room and repeats the process again it takes a permanent
line neutral and circuit protective conductor into the next ceiling rose and he's terminated in the
loop terminal for the line the neutral terminal and the earth terminal within the accessory and
the process is repeated again when working in ceiling roses and pendants in domestic dwellings
you may also be faced with cable colours pre 2004 pre 2004 the line conductor was red the
neutral conductor was black and as it still is the circuit protective conductor was identified
with green and yellow sleeving the process is identical just care must be taken to make sure
that you're familiar with both new and old colours when working with in ceiling roses and pendants in
order that we make the appropriate connections I hope this presentation has been some help
