Nuisance tripping of kitchen lights

[marconi]

If after doing the necessary testing you find no fault, I suspect the problem to be a high in-rush current when the switch is first made. LED lamps and their drivers do have high but short duration in rush currents and in your case you turn on 4 at the same time.

You could fit one of these:

an inrush current limiter with a rating of 16A.

PS: Or change LV Luminaires for Mains ones if that is a cheaper solution. In our new kitchen we have 16 Saxby 7W Mains GU10s supplied by a 6A type B mcb all switched on together.

Given the OP has stated he can't access the transformers, this change over could be tricky!

Murdoch - yes. I have just read in his first post like you did that he stated he could not gain access - good point.

I dispair when I read threads like this !

Don't fret - by reading your advice and acting on it folk will be learning from standing on the shoulders of a giant.
