Wiring a
ceiling rose
Please read
the disclaimer
before attempting any electrical work. If
you are uncertain then contact
a qualified electrician.
 |
Un screw
the ceiling rose. |
|
If you
have already took the light down and
are unsure which cables are which then
click the link to the left. |
 |
Make
a note of the wiring order or even
take a picture if it helps. I always
look for the brown tape/sleeving to
identify the switch wire. If one of
your wires in your ceiling rose hasn’t
got any tape/sleeving on it then it
is a good idea to put some on. If
you can’t identify the switch
wire it is the wire connected to the
brown wire on the ceiling rose.
|
Carefully
un screw the terminals and gently
slide the cables through the rose
making sure u don't damage the cables
or remove the tape/sleeving leaving
you no identification of the switch
wire. |
|
Take out the knock out
from the new ceiling rose to suite and
then re secure to ceiling. |
|
Check the condition
of the cables, it’s always a
good idea to re-strip the wires and
double over the cables for good practise.
copy your picture/diagram
and place neatly in the correct terminals
and tighten
(Make sure that the connections are
tight and give them a gentle pull
to check).
|
 |
Screw
the ceiling rose back on and make
sure there are no gaps.
You may now place your bulb/lamp
in the ceiling rose. |
More Information
Wiring a ceiling rose may look confusing
at first. But the aim of this guide is to
help you do so correctly and to make it
as easy as possible. The way a ceiling rose
works is the power either comes from the
consumer unit or the lamp before it (a radial
circuit). The power will be sent from one
lamp to another via connecting blocks that
are connected to the live wire that goes
out.
When a light is joined to the ceiling rose
it will be wired into the neutral terminal
as well as the live terminal that is shown
in the ceiling rose. For the rose to work
correctly it must be interrupted by the
switch.
This is an easy task as a cable (switch
wire) will be added. One of the wires that
comes from the switch wire will be connected
to the live terminal. This will take the
live current to the light switch. The earth
cable goes straight to earth and should
never be used as a live wire. It will then
be connected to the switch terminal located
in the ceiling rose. This in turn will bring
the live current back into the rose to complete
the loop.
To break it down we have live current
going down to the switch of choice and
when the switch gets turned on it will
allow the current to pass through the
switch and to the ceiling rose which allows
the love current to reach the light.
"The
most common mistake I have found as a professional
electrician is that people who attempt DIY
sometimes connect all the black/blue cables
and all the red/brown cables together. This
can be very dangerous because as you can
see from our diagram you are effectively
connecting a live to a neutral (which will
go with a big bang and trip the fuse)"

Tips
When choosing a position
for a new ceiling rose I always bring the
cables out directly next to a joist. If
this is not possible then mount a wooden
batten between the two nearest joists to
provide a secure fixing for the light.
If you are using metal/chrome/brass switches
always make sure the switch is earthed.
Check if your lights have
earths, if there are no earths in your switches
or lights get in touch with a qualified
electrician.
Always use insulated tools
when working with electricity.
Take your time and
double over your single cables as good practice.
