Wiring advice please

[Bradley6969]

Some wiring advice please, only apprentice starting to connect lights more so want to learn
Feed in and out 3 Gang Switch
Switch 1 2 Way Spots
Switch 2 LED undercupboard tape
Switch 3 Plinth

Feed in - L to L1, N to Wago
Switch 1 - 3 core between switches Black Is Com on both Brown is L1 on both and Grey is L2 on both, To Light from L2 and N to wago

Switch 2 - Link from Switch 1 L1 to Switch 2 Common, To light from L1 and N wago

Switch 3 - Link from Switch 2 Com to Switch 3 Com and Feed out L to Com and N out from wago, To light from L1 and N wago

Sorry for bad drawing haha

The question was a teaser for you. Supposing that the cable you've shown as 3c+E had be first-fixed as only a T+E. Could you still make it work as intended? (Spoiler; yes, there are two ways to wire it with T+E that will work correctly) What caveats might apply to those alternatives?

Sparks who have been around the block will know that there is yet another way to make it work without the T+E loop out / in between the switches at all. Just one 3c+E between the two will do everything and it doesn't even require using the bare core for anything other than CPC. But, unlike the other methods I mention above, it's not correct or compliant and should never be used. If you're prepared to really bodge things up and ditch the CPC, you can still make the 2-way work with the 3c+E missing altogether and just re-purpose the bare core in the T+E. Nasty, but understanding these things helps you understand electricity in general.

Also he told me he likes to wire lights if there’s a feed in and out at the switch to same point

Yes it's a preference. It puts fewer terminations along the main run of the loop in / out which is likely to be carrying the heaviest load. OTOH, it requires three cables in one terminal, which may not be ideal. There is something to be said for running the line loop in / out through a Wago like the neutral, and tapping off to the local switches.

think what you need is a couple of richard burns' switching diagrams. they're the dog's bollox.

This thread indicates you are no longer an apprentice?

Dali would've been proud of that drawing!

No no, that's completely unfair.
It's a Mondrian

Are you sure? I had Miro down for my second guess...

Before I scrolled down, I thought that was a photo of a DIY attempt at installing a single cable underfloor heating element.
