I have to put a fan in a shower area,so have gone for the 12v manrose bathroom fan which comes with a transformer. I was hoping that when you put on the light switch via a pull cord that the transformer can be wired up so that the fan came on as well. My electrician friend now informs me that I will need a cord for the light and a cord for the transformer. Is their a way of connecting the transformer and the light switch so i need only one cord as their will also be a cord for the electric shower. Thanks. Lawrence:confused:

if your lights are wired are wired in loop in then...........

a 3 core from your bathroom light to a 3 pole isolator, then a 3 core from your isolator to your 230v side of your transformer, then a 3 core from your 12v side of the transformer to your fan.

its as simple as that. about an 1 hrs work.

if your wired feed to the switch then a bit more complicated but not much more time.
