    Hey lads , thanks in advance for reply just a query i have ,

    Doing a job for a mate of mine who is looking for an extract fan in the bathroom , he wants me to wire it off the shower pull chord switch, it requires a permanent feed , neutral and live for the fan.

    Would you put two seperate spurs in one for the permanent and one for the switched live and loop the neutral between spurs for the led?? or what would people suggest . thanks again.

    I assume that this is an instantinious type and therefore 8.5kW or more. It would therefore unsuitable for a supply for a fan.

    This is best taken from a local lighting circuit.

    yeah fishdog 8.5kw , I was going to take it off the lighting circuit as i would normally do but the awkward f*** that wants it done wants the fan to come on when he pulls the pull chord switch and go off 5 mins after the he finishes his shower. Would two spurs with 3 amp fuses be against the regs??

    The fan requires a permenent live, 9get this from the switch feed going to the bathroom light), a switch wire, a neutral and (to do it by the regs) an earth (get all of these from the bathroom light) All of these would generally be available in the attic or above the bathroom ceiling. First bring them to a fan isolator switch and then to the fan. Wired like this it will come on with the light.

    Keep the fan isolator well away from bath, shower and sink. Perhaps best on the ceiling. Same with the fan if it is mains voltage.

    I generally use a 12 volt vortice fan with 3 year warrenty. These units can safley go in a shower cubicle so are very effective. They are also quite quiet.

    Health warning: Always be careful with electrical appliences in a bathroom. If in doubt get an electrician to do it.

    Forget the shower switch, if he wants fancy have it controlled via a humidity sensor.
    You will still need to have the 3 pole isolator outside and of cours run it off the lighting supply.
    ATC out in tallaght will have the sensor for about 90 plus vat

    Now that sounds pretty cool, although a bit pricey!

    Perhaps if I shop around....Who makes this Eoghan???
