Loop
in ceiling rose lighting method
In this method,
a twin and earth cable runs
from the consumer unit to each
of the ceiling roses one after
the other, then a twin and earth
cable runs from each ceiling
rose to the switch.
|
|
 |
The switch cable is the wire that carries
the electric from the loop terminals on
the light to the top of the switch and then
when you push the switch it carries the
electric back to the light, lighting the
lamp up.
| |
| 
| Switch
off and isolate all power to
the circuit.
|
|
| |
| |
if you have 3 * twin and
earths at your light then
more than likely 2 of them
are the feed in (cable from
consumer unit or light) and
the feed out (to next light)
(live, neutral and earth)
and the other is the switch
wire.
|
|
| |
| |
| 
| check
your continuity/voltage tester
by making contact with the end
of the two leads, when you hear
the beep, it’s in good
working order.
|
|
| |
| |
| 
| Go
to the light and pick a cable
(this is trial and error) place
each end of the continuity/voltage
tester in connector blocks and
connect 1 to the “Live
colour “ and 1 to the
so called “neutral colour”
|
|
| |
| |
| 
| Go
to the light switch and push
as if to turn the light on,
if it beeps then you have successfully
identified the switch wire,
if you have failed then repeat
the steps on 1 of the other
2 remaining cables.
|
|
| |
| |
| 
|
Sleeve/tape the switch wire
up the correct colour red/brown
and follow the steps on wiring
a ceiling rose
If you have more or less cables
at your light, by following
the steps you can trace and
identify any cables location.
