One Way Lighting Circuit

There coming from the consumer unit or another ceiling rose in the circuit.

To the consumer unit/fuse.

Cheers Gaz, cheers Ian, cheers Ian (Spark).



I'll be extra clever and throw in the 2 way too!

There either going to or from the next light or from the consumer unit. Hope that helps, dave

 

[Bane]

Thanks Dave

If you wanted to add another lamp to the circuit, just run another piece of T&E from the ceiling rose to another lamp. Connect the new neutral to the existing neutral. The new phase to the switched phase (the one with the sleeving and the new CPC to the existing CPC This is called the "loop in method"

 

[Bane]

Loop in method. Ok.

And the cable used is T&E 2.5mm? 1.5mm?

Phase is Live?
CPC is Earth?

Getting to grips with terminology too.

1.5mm for lighting
2.mm for sockets

Generally lighting circuits are in 1.0mm T&E, socket circuits are in 2.5 T&E.

Try to get out of the habit of calling the Phase live and the CPC earth especially the later. They have different meanings as you will find out in the next few weeks

Thanks guys.

So in T&E you have:

Neutral
Phase
CPC = Circuit Protective Conductor (Earth sleeving?)

Correct?

Finally, in the diagram we'll have 1.5 going into the light fitting from the CU and 2.5 coming down to the switch?
