Adding loft lighting

[Tony Myers]

I've added a junction box with 3 connection blocks to a lighting cable in the loft in order to add a spur for loft lighting. The cable I've broken into operates the landing light and other on the upstairs floor. I've followed 2 wiring diagrams, both of which have identical layouts, but I can't get the loft light to work. Instead, when I switch it on, the landing light comes on instead. I'm using an intermediate switch (live to L1 & neutral to L3) - is that the problem?

From what you describe you don't really have much of an idea what you are doing, and you could end up doing something very unsafe.
Please get a local electrician to look at this simple job for you.

you can't take a feed from an intermediate switch. as abve. get a local spark.

Simply to add two ordinary lights to the loft.

You might have chopped the 3C for the intermediate switching

Time to get a local sparks in
