Before
working on any electrical circuit
isolate the supply by switching off
the main switch and remove the fuse
to the circuit that you are working
on, If it is a circuit breaker
switch off the main switch and
circuit breaker. Place a sign saying that
you are working
on the circuits on the consumer unit, then nobody
will restore the power whilst you
are working on it.
If
you are not 100% certain what you
are doing call a qualified
electrician. Building regulations
are changing all the time and
modifying your home electrics could
be against new rules and could
invalidate your home insurance, if
in doubt check first! |
Wall lights can add an attractive
feature to a room and are not
difficult to fit, the only hard bit
is making good as you will have to
make the plaster good once you have
routed the wires to the switch and
the wall lights.

The up lighter above is one of a
pair and are fitted either side of
a chimney breast, these were fit
before the Plasterboard and coving
were fit.
The first job is
to decide exactly where you want
the wall lights placing, often they
are placed each side of a chimney
breast or in a alcove. If there is
decorative Coving above where you
require the wall lights then it may
be easier to feed the wires from
The floor (providing it is not a
solid floor), this would make the
job considerably more difficult as
there probably will not be a
Lighting circuit wire in the vicinity
which will mean fitting a
Fused connection unit to the ring
main to feed the lights. In most
cases it is possible to route the
wire behind the decorative coving
without damaging it.
Mark out and Fit the back boxes for
the Wall lights, Chase out the
plaster to the ceiling and remove
the floor boards directly above
where the wires are going to be
fed, Using a masonry drill on slow
speed drill a 10mm Hole through the
ceiling until you have an hole
suitable for feeding the wire down
to the Back box. Find a suitable
Permanent live wire from the
lighting circuit, This can be
easily identified as it is the
lighting wire which runs from one
ceiling rose/Junction box to the
next.

Isolate the electricity by
switching off the main switch and
remove the switch, if it is a
circuit breaker remove the wires
from the top of the circuit
breaker. Test the wire with a
suitable Tester to ensure the wire
is not live! Cut the wire in half
and install the Junction box as
shown below.

This is relatively
simple as there will only be
3 Lives, 3 Neutrals and three
Earths, be sure to fit Green and
yellow earth sleeving on the earth
wire. You now have a a feed
wire which you can use to power
your new wall lights.
Some wall lights Have a Built in
switch which means that you don't
need a switch on the circuit, but
this makes it difficult to isolate
them and if in the future you
decide to change the fittings for
some without built in switches you
cannot turn them off without
isolating the whole Lighting
circuit so fitting a separate switch makes sense.
Decide where the switch is to be
placed (ideally it needs to be in
the same Gang switch as the
existing light switch for the
room), Carefully chase out the
plaster with a blunt chisel and
make sure you do not damage the
existing wires running to the
switch! You might have to Knock out
an other metal plate from the back
box to accommodate the new wire,
Fit a grommet as well and feed a
wire long enough to reach from the
switch to the new feed wire that
you prepared earlier.
Fit a junction box to the End of
the feed wire, you will need a
15amp Junction box with 4
Terminals. Wire the Junction box as
below-
There are 4 terminals inside the
junction box, these are not coloured
or marked in any way, I have
coloured them in above for clarity.
All 4 Earth wires go to the same
terminal
The Neutral from the feed and the 2
neutrals which go the the wall
lights are all in one terminal
The live wire from the feed and the
Live wire to the switch are in the
same terminal
The wire returning from the switch
(switched live) which is black
needs some red sleeving placing
over it as this wire is live once
the switch is on, This wire and the
two Red (live) wires which go to
the wall lights are in the same
terminal. You now have a circuit
which once the switch is on, will
light up the wall lights.
You should familiarise your self
with this arrangement, Follow the
current with your finger on the
diagram if you do not fully
understand it!
The connections at the switch
are simple as they are the same as
for a normal lighting circuit.
Ensure you place red sleeving or
red insulation tape over the
switched live wire.
