DIYnobody said:Can anyone help we with the wiring of this, see diagram, can you tell me if im on the right lines?
thanks in advance
No No No .......looks like your planning on using the cpc (earth conductor) for the overrun timer supply.
Going by your diagram odds on the switch is being used as a junction, so you'll find Permanent live / switched live / neutral & earth there. You will need to take via 3 core & earth cable a feed from each to the fan. Connect perm live to L terminal of fan / switched live to timer terminal of fan / neutral to N of fan & if no earth terminal sleave the conductor and terminate in a chockblock inside fan housing.
If this is for a bathroom dont forget the bonding.
You can wire a simple fan in parallel to the light. It will then come on all the time the light is on. thats OK.
However, your fan appears to have a Timer option, where the fan will run on for a time after the light has been turned off. That can only work if you have a permanent live supply to the fan, even when the light is switched off.
If you can't arrange that, connect the Timed and Permanent Live terminals on your fan together, and then it will run like the simple fan you had before.
Bonding is the safety electrical connection, using Green and Yellow wires, of the earth wire in all the electrical circuits that enter your bathroom, to all the metallic pipes that enter your bathroom.
This is typically lighting circuits, sometimes heating circuits, immersion, central heating pump, and hot water pipe, cold water pipe, flow and return radiator pipes, sometimes flow and return boiler pipes going to hot water cylinder.
We will not cover Bathroom Supplementary Bonding here, you will find lots about it in the Electrical UK Forum already.
p.s. I think you need to read the pages linked in my post of Wed May 09, 2007 3:36 pm since you do not seem to know the background to what you are attempting.
