Connecting a fan to shower power

[tirfor]

Hi all, a newbie requiring advice.
I have been asked to fit a fan within a bathroom with the following constraints:
1. fan needs to work in daylight when light is off.
2. ideally on a timer so steam can be removed after showering.
3. humidistat not to be used as past units did not work to well.
4. be able to use 3a fans.
5. cheap as poss so no expensive fans or expensive pir's

So i have thought it would be best to connect the fan to the showers power.

My question is:
1. Is this ok to do or is there a better idea?
2. A timed fan requires a live and switched live, so is a fused spur available with twin fuses?
3. My idea is to tap into the supply side of the shower switch to provide the live feed and then tap into the load side of the shower switch to provide the switched live. Both lives will go to separate fused spurs (located in assessable attic) then both spurs will be connected to an isolation switch (in wall be bathroom door) then of to the fan. Is this ok or am i missing something?

Cheers for your help.

OK, I may be seeing light at the end of the tunnel finally.:clap:


Am I right in saying, as Geoffsd says, that technically speaking there is no reason why a shower cable cannot be used to supply another circuit if all calculations are OK. But it’s not recommended as all cables should have minimal breaks and joints in them, which may cause problems.


If this is the case, I understand but I couldn’t understand why I was getting ‘no you can’t do it’ but without a reason, hence I couldn't get my head around it. Any other reasons?

The current sensing device as you guys have stated would have been my best option to deal with my job brief, but I just expected some sort of readily made device for sale not me making it from scratch. I feel a trip to Dragon's Den may be in order
I can't believe others have not had to same problem.

Good man welcome to the forum, I did answer your question earlier to be fair, the answer was we just do not do it, it is creating a joint on a dedicated circuit supplying a heavy load in a bathroom, anyhow you have now seen sense and again welcome aboard.

I think my stay here will very very brief
time and too little knowledge. If you don't know why something is so then just say so or, better still, don't post a comment.

Don't trip over the rug on the way out
The answer was given several times, are you struggling to read as well as seeking attention here, off you go then :waving:

If I've read things correctly this is a low power circuit running a pump, and is not on a 6mm cable. Bearing this in mind, I can see why the OPs is asking for reasons why it is bad practice to feed another item of low power equipment from this same circuit. Daz

looking at post #1, there's no mention of shower pump, just shower.

Apologies, I think I must have read something in another post and got confused. Is it Friday yet?!?!

I tried some Londons pride last week Tel and didn't like it, had some old peculiar the week before actually and it was quite a nice drop.

2 bottles of OP and MDJ won't know if he's Mike or Mark.

Try Hobgoblin Mike. V. nice. Daz

Why doesn't that surprise me.


As for this thread, what can I say? It's about time it was put out of it's misery.
