I am about to add some lighting to my loft, picking up the power from a ceiling rose. The power in to the ceiling rose will be diverted to a junction box, and replaced by a power in from the junction box.
O.K. - now I have a junction box with power. My DIY book shows the usual way of wiring a switched light.
Live -> Switch (red) Live Light fitting (red) Neutral
Not at the moment. I plan to pick up the permanent LNE at the other end of the loft, using a junction box. I then plan to run a spur from this junction box from one end of the loft to the other end of the loft by the loft hatch. At this point I need to add a switch, before I go on to the light fitttings.
So the question is, do I spur the permanent LNE to a junction box near the loft hatch, then proceed as usual with a junction box system, or can I dispense with the junction box by the loft hatch and instead just use a choc bloc in the switch back box to complete the circuit? i.e. permanent LNE -> switch + choc bloc -> light fitting(s)
Bob suggested using a double pole switch but I don't seem to have one in stock at the moment - although I was a bit shocked at how much stock I have once I started rooting through all the boxes.
But I'd carefully open the cable and only cut the live to insert the single pole switch. Earth also cut and sleeved, rejoined in the back box's earth terminal.
