30v on 2way switch when turned off??

[aaelectric]

Went to a job today, where the client had removed 3 halogen bulbs to install LEDs. When the light was turned off from one side it would make the bulbs flicker with switch off, but if it is switched from other side it was ok. I dissconnected 2way switch and if was working fine. There is a new cu rcd protected. i did not have my ir tester to hand but i was thinking a damaged leg on 2way cable? What are you thoughts? If it was a damaged cable rcd would trip tho? But it may be damaged between lives? I had mu continuity tester and nothing was showing on that

Capacitive coupling

If the switches are linked with 3+E, wiring it a certain way can reduce, or even get rid of, the effect.

Was there a dimmer switch installed?

No dimmer switches.
sorry could you explain capacitive coupling

Capacitive coupling - Wikipedia, the free encyclopedia

Scroll down to parasitic coupling.

It does seem (like Archy said) that this is more common with 3 core + E as opposed to T&E (in relation to GU10 LED'S)

Well i think il IR test and if that shows ok then halogen it is? , pulling in new cables is a no no. Thanks for your responses. Il let you know how i get on.

You could try placing a resistive load across the fittings

or a snubber. going back to halogens id like the RAF replacing it's strike fighters with biplanes. get a grip. sort it out.

mmm Biplanes....the very first thing i sold on E-bay was a wooden propeller blade from a WW2 Supermarine Walrus Is that random enough for you?:willy_nilly:

Look up snubbers. An RC snubber should sort the problem. Happy to be educated if i am talking rubbish.
