conventional method?

[martC]

two lamps, two switches to be two way wired in the conventional method. I thought the phase went straight into the ceiling rose but someone else is telling me it goes straight to the common in the switch.
Please help cos I've got to do a circuit diagram of it on Tuesday and I'm starting to get worried.
Oh, I've got to wire it in singles, too.
Cheers.

plenty in the wiki.

I'm not finding what I need. Maybe I'm searching for it in the wrong way? I've put in Two way switching, conventional method, wiring lights, circuit diagrams.
Where am I going wrong?

What is the conventional method?

There is lots of different ways to wire 2 way switching.

There are diagrams of every different way to do it in the wiki.

This is the problem. Conventional is when it's looped at the ceiling rose and conversion is when it's looped at the switches but I've only seen this mentioned in our practical course book for City and Guilds.
Is conventional another explaination for loop in method?

When you say two lamps, two switches, two way, do you mean two lamps coming on together, switched from two different positions?

Conventional to me means 3 plate. But there are two other common methods:

JB (which is similar to 3 plate except all the connections usually made in the rose are made in a JB, with a single cable then feeding to the luminaire.

But more commonly is the method where the live loop is taken to the switch.

I like the 3 plate method, because you have the live loop easily accessible in the ceiling, whereas with the others, it is not.

If you want a neutral at the switch position, that is easily done when wiring the circuit.

But if you want to wire it in singles, it would be a conduit job, and this is very different.

From the supply would come a live neutral & cpc. The live drops at the first switch to the common. The neutral & cpc go to the first luminaire, and loop to the second one, along with a switched live.

Then a switched live drops from the second luminaire to the common of the second switch. Link the two switches with two strappers and you're done.

But I really shouldn't have to do your homework, should I?

Sounds like you are wiring it in conduit/trunk with singles, in which case, take neutral to light and live to switch C.

hang on.....

But there are two luminaires....Tch! Can't get the staff....

Not as good as my method.. Miaow!! But excuse my pathetic lamps....

If its in metal conduit, don't forget the eddys!

Tis true....
