Help req.

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

am i being a dumb --- or cant you wire the fan 230v side and light on one circuit ?

No you're not, is the second pull cord an isolator for the transformer and fan?

 

[oldlaw16]

as the electrician is a friend.he is doing it as a favour. I have NO idea about electrics so am using the internet and this forum to try and find someway of doing this so their are no pullcords all over the place. if you could just explain this in easy terms so that I can give it to him. ta

My electrician says that the transformer has to have its own power supply? Thats the fan right enough. anybody any ideas regarding wiring.

ITS A FAN !!! why does your electrician say it needs it own power supply

230V to remote transformer...12V from tranny to fan...ask your electrician

I require the light in their as well working of the 1 switch. Is this right. 230v to light,light to transformer?

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.
