kwak250 Posted April 5, 2022 Share Posted April 5, 2022 I wired a strip light a few years ago to a socket with an on/off switch This was led and it kept tripping the Safe-t-cut I then just plugged it into a extension cable and it worked fine and still does Now today i did the same wiring 2 led spotlights to a switch and i am having the same problems with the safe-t-switch Looking online it says it an 'inrush' which is causing this to trip Can anyone help with what to do as if i leave it switched on it is fine but as soon as i switch it off the breaker is tripped If i connect this to a extension cable it is fine. Many thanks Link to comment Share on other sites More sharing options...
kwak250 Posted April 5, 2022 Author Share Posted April 5, 2022 Ok just worked this out the extension cable from before had a surge protector(data extension cable) So that is what is stopping the inrush tripping my safe-t-cut So is there any way i can do this without having to get a surge protector extension lead I expect the latest model safe-t-cut would be a good idea but must be a cheaper way Many thanks for reading this Link to comment Share on other sites More sharing options...

transam Posted April 5, 2022 Share Posted April 5, 2022 What type of safety cut is it, ....? Link to comment Share on other sites More sharing options...

One lamp shouldn't be tripping the beast, inrush wouldn't be that big on a domestic install (it's definitely a problem on large installations). The surge arrestor shouldn't making any difference, could possibly be the extra cable length. Most odd. 1 Link to comment Share on other sites More sharing options...
kwak250 Posted April 5, 2022 Author Share Posted April 5, 2022 Hi its a very old safe-t-cut model As soon as i run it through a cheap Data extension cable it works fine. If i try to connect without just with the standard wall switch it will trip Probably worth changing yo a newer model Link to comment Share on other sites More sharing options...
xtrnuno41 Posted April 5, 2022 Share Posted April 5, 2022 It only happens when switched off. I could think the switch isnt right. It should switch off, but maybe not. Contact still running with a resistance then. Oxidized contact? Voltage influenced and there for the safety cut. As the safety cut sees a differential between live and neutral and switches off. Is it an adjustable one? With the surge arrestor, you still could have a loop in which the safety cut feels comfortable. 1 Link to comment Share on other sites More sharing options...

If you post a photo we can show you how to tell if it tripped on over-current or earth-leakage. 1 Link to comment Share on other sites More sharing options...

It would also be helpful to see how the LED strip is powered. 2 Link to comment Share on other sites More sharing options...
