how to wire a selv extractor fan

[NadHuh]

Can some one quickly tell me how I can wire a extra low voltage extractor fan, I know it needs a fan, fan isolator, and a transformer but how will the wiring go to each of these. Someone's already done the wiring but its not marked and not making sense so I need to learn how it's wired normally. And if I can remember right there are 2 twin and earths at the light there's 2 twin and earths at where I think the isolator is and there's a twin and earth at the transformer and 1 at the fan.

General rule for homers if you have to ask how to do it, you probably shouldn't be doing it. Remember your foreman/boss/whatever can't check it over once your done and if it goes ---- up it'll be on your head mate.

EDIT: I'm a 1st year apprentice and have wired hundreds of these.

Be afraid, very afraid.
Your experience of Bosses..limited

Your Boss's experience of apprentices,, probably vast.

Have you noticed you get the crap jobs that no one else wants,, like wiring up hundreds of Selv fans??

Ah see but I'm my boss' first apprentice!

Just realized that you're right though. When we're second fixing a house we'll go round and do so much together then I'll be left to finish what's left while he installs the consumer unit. Funny how the bathrooms are all left until last! TBH though I don't mind the extractor fans we install as they're a piece of "p" (Airflow Icon's).

Just out of interest are you guys installing a fused spur on the extractor as well as a triple pole isolator ?

i fear this forum is starting down the persecution road.

would it not make more sense to have some form of vetting on signup to give some form of proof that you are infact qualified or training before being allowed membership?

some of the posts do indeed seem a tad harsh if the op is infact a trainee (maybe he is or maybe he isnt) and going by this and various other threads i would feel a little intimated to make posts myself if i was still a trainee.

understandably we get annoyed/ frustrated at the Electrical Trainee/diy posts but you cant always diferentiate between the struggling trainee or the diyer - the forum used to be a lot friendlier when i first joined 7 years ago and should return to that - proving some level of competence is the only way of achieving that.

the forum has a section for trainees. it's up to them if they want to swim in the deep end without any armbands on.

not a great deal of point for any other sections then as the only questions that can be asked are by qualified sparks who seldom need to ask much, and if they do then it would be much more advanced questions to the majority seen on any of the sections.
