adding extra light

[justdan]

ok perhaps over sensative.. i am more used to technicla forums and Computer related issues where i usually stand my own ground...

ok in short..

i have a 2 gang light switch.

on the first switch is working

it has an earth cable and two others... (both red)

i want to add a second light on the second switch

how can i power the second fitting from the first (from the switch box)

This isn't a proper electricians answer, but this is what I would do (though it may not be the 'right' thing to do)


Identify the Neutral at the ceiling rose of light number one and run it to light number 2.

Identify the permanent live in the switch, put a link in between this and the C of the second switch. Take the switched Live from the second switch up to the light.

One of those is the permanent live, the other is the switched live. You should look at the diagrams in the For Reference section to see how lighting circuits are wired..

You can't, not directly, as there is no way that the switch can provide a neutral for the new light.

1) You could do what johnny_t suggested.

2) You could take permanent live & neutral from the ceiling rose of light #1 to the rose, or a 4-way junction box for #2, and from there run a conventional twin & earth switch cable to the 2nd gang of the switch.

3) You could replace the existing switch cable with 3-core & earth, and use the extra core to bring neutral to the switch, link the two COM terminals as per method (1), and run T&E to the new light carrying switched live and the neutral joined at the switch to the neutral from the 3C+E with a piece of choc-block.
