Hello people.

Well, for my homework, I've been asked to research one way lighting circuits.

On google I've come across a number of sites and not many on wikipedia.

Anyway, seeing as how we haven't even covered lighting circuits at college yet I found this a bit poo. I digress, sorry.

Can someone please explain to me a one way lighting circuit in relatively simple terms?

Cheers.

Bane,

A one way light circuit is basically one switch to switch the light on.

A two way is where the are switches at different locations switching the light on.

You can also fit intermediate switch on the strppers so you can switch light on at three or more location depending how many intermediate switches are fitted.

Hope this helps you out.

May not get much info about switches on wikipedia as you will find it an American website.

Not understanding that diagram Spark-Doctor.

Phase=Live?
CPC= Earth?

Red sleeving indicates that the neutral becomes a live also?
If yes, then why red sleeving and not brown?

Explain please.

Ok, got that thanks mate.

One thing. What's going on in the top right corner of the diagrams, where they are circled?

Explain please.

Sorry, but I like to know all the ins and outs, I can't just accept things.

The circle bit represents the light fitting

The circle is showing the ceiling rose with the termination points.

Just to add. These pictures are showing the wiring in T&E. If you were to wire it in singles through conduit you would be able to run the correct color wiring and would not need the sleeving. The wiring diagram would be the same though.

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