Electrical problem. My extractor fan keeps on tripping my RCD whenever i turn it on. Answered
I recently installed an Xpelair XX150T exractor fan in my bathroom. This model has an intergrated timer (which i do not want to use so i didn't connect up the unswitched live) and is supposed to be run off of a 3 pole fan switch.
From my distribution board the cables are going to a switch and from there to the 3 pole fan switch and on to the fan. At the distribution board the live is connected into a 20Amp breaker and the neutral is connected to the main neutral bar.
Whenever i switch on the fan the RCD trips. I've checked my wiring and i cant see any reason for this.
