Electrical problem. My extractor fan keeps on tripping my RCD whenever i turn it on.
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.
