Two way switching plus intermediate

[La Poste]

I mean I was taught at work to wire everything to the switch and terminate all the neutrals there but with singles you can terminate the neutrals anywhere.

What about junction boxes? They are OK to terminate into so taking this idea further it must be OK to terminate neutrals into connector blocks anywhere that is convenient so long as you don't cross neutrals, the same can also be said for CPC's, so long as the CPC is continuous why not make all your neutral and CPC terminations inside a light fitting for instance if that is the easiest place to do it or am I barking up the wrong tree?

As regards safety it is safer to not stuff conduit with additional and unnecessary wiring when you can slim the whole job down to half the wires.

I mean surely the golden rules are don't cross neutrals and maintain CPC continuity and that's it, the rest is up to me.

Both methods of wiring are fine. If it is easier for you to wire the switching in 2-wire then there is no problem with this.
I quite like 2-wire switching but it is not always sensible to do depending on the physical layout.

Terminating in light fittings is standard and much better than using another junction box, so long as the connectors are appropriately enclosed by the fitting.

Get the electrical regs bit right and you are OK, the way you get it right does not matter.

Get a qualified electrician in before you kill someone!

I think thats a bit harsh! La Poste is simply asking a question!

There is nothing wrong at all with the way he has suggested wiring it - and its the correct way for conduit or trunking systems

Bit of an unusual response for members of this Forum, the guy was asking a simple question on something he could'nt get his head around. Is'nt that what were here for ? to help each other out.

There’s times when I wonder.

If you are going to use singles in conduit throughout the installation then don't forget to run a new feed with the strappers otherwise you'll not be able to use last switching location to feed the next light on the run.
2 - wire lighting configuration = conduit
3 - wire lighting configuration = T&E

Thanks very much for all your advice and I didn't even have get a qualified electrician in.

Not sure if I am qualified, City and Guilds 2330, 16th edition and 2391 and am awaiting my 17th edition course.

Experience is what I am lacking in places and hence the job usually takes me four times longer than a well experienced Sparks.

I made a beautiful conduit system next door with lovely bends and flexible conduit here and there.
Trouble is it has so many bends it's taking me a month of Sundays getting all the wires through haha.

I'll post some pictures when it's done.

It shows skill to put loads of bends in 1 peice of steel tube, but like youve said, it doesnt help when your trying to wire it. Thats when a conveniently placed box can help out no end.

Those diagrams are HORRIBLE! No wonder there's all this talk of bad colleges and tutoring if that's what they're giving out! Try these:

Sorry, just realised I scanned the T&E ones not the conduit ones. I'll leave them up anyway and do the others later.

I appreciate that this is an old post but, just for completeness, there are some valid reasons why you would not use a two wire control in a domestic environment, it is discussed in this article in some detail:
