Work this one out...
I was installing an inline shower fan/light which required a switched live, neutral and a permanent live. I took the switched live and neutral from the switch and the permanent from a spur (also feeding underfloor heating) connected to the ring main which was RCD protected (the lights were not)... But everytime I turned on the spur it tripped the RCD...I've solved this temporarily by connecting the switched and permanent live both into the switched live from the switch...But why was it tripping???
