Hi all
I'm new to this newsgroup so please forgive me if this has been covered
recently.
Basically my parents asked me to investigate a dodgy light socket in their
house, it is in an extension to the house built some 15 years ago. It is a
triple switch operating 3 separate lights - 2 outdoors and 1 in the middle
of the ceiling. These lights are not operated by any other switches so they
are 1 way.
There are 4 cables coming in to the switch all twin and earth. One comes up
from the bottome and the other three from the top - the bottom one comes
directly from the fuse box.
Question is - how do I wire it up? The switch has 3 COMs and L1 and L2 for
each switch. I gather that the live from the fusebox would go to one of the
COMs and linked through to the other 2. How would the wires from the 3
lights be wired?
Any help would be most welcome.
Thanks
Martin
Are all the black wires running to the switch point as well ?
You might also have bare copper earth connecting conductors in the box that will
need to be covered in green / yellow coloured plastic sleeving and placed in the
earthing terminal of the back box, or to a screw terminal block, to keep them
out of the way and make sure they don't touch anything else. Do this first to
get them out of the way.
The red wires should be connected to either the "L1" or "L2" side of the
switches depending on which way you want the switches to operate, i.e. up for
on, or down for on. The supply red is connected with links of red wire of the
same size to each of the "COM" (common) terminals.
All the black coloured wires should be connected together inside an insulated
screw terminal block (chocolate block) and wrapped in some insulating tape to
make sure none of the bare copper can touch against the metalwork of the back
box or the switch plate. You can tuck the block into a corner of the back box
first to keep it out of the way when you put switch back on.
