Dundee 2 way sounds like more than anything to do with light switches

Barnaby Stedman · May 21, 2019

what are you actually trying to say???? You realise your op doesn't make a huge amount of sense. How is 'dundee' relevant?

His first post makes sense if you understand what a "dundee wiring" schematic is. Obviously he has assumed it's a common slang phrase for a system, much like 3 plate wiring.

Unfortunately for the OP, I've never heard of it, an neither it seems has anyone else in this thread.

thats what they call it a dundee 2 way iam from fife scotland dundee is up the road its haha its a 2 way but a very difrent way of doing it

This name for it is probably only used in your particular area. Can you give some more details on the cir uit and then maybe we can work out what it is?
Is this wired in conduit or T&E, how many of what type of cables do you have at each switch.

There's only really two ways of wiring a two way, the standard method or the switch conversion, though there are many ways to physically connect them depending on each installation.

A standard 2 way has a live to the common of one switch, 2 straps between the switches and a switched live taken from the common of the other switch.

A switch conversion has a live to L1 and switched live from L2 at on eof the switches with 3 conductors linking the two switches (com to com, L1 to L1, L2 to L2)

i've seen ( only a couple of times) where both 2 way switches had 3 core/E's back to the light position. was like spaghetti junction in the light fitting. 2 T/E and the 2 3 cores+ the S/L &N to the fitting. 5 cables in a ceiling rose.

Dundee wiring? It's a piece of cake

I've installed two-way switching like this more than once. If the light is a ceiling rose, it helps to have some of the miniature Wagos to fit the additional junctions in the rose.

I quite like jobs to fix lights where everything has been disconnected. The more wires the better, especially if some connections don't belong in the standard rose terminal blocks.

One of the best ones I had to fix was the switching for a light in another room that (for historical reasons) went via the rose in a different room. And a smoke alarm installer adding a wireless room alarm had mistaken the blue (old colours 3-core) for N. The light in the other room then never turned off completely.

I don’t know that I would call your standard method ‘standard’, at least not now.
It’s this method which causes borrowed neutrals when used on stair lighting.

Your mentor should be telling you to identify switch wires brown and to earth metal switch plates.
