Shower fan wiring

[jezer]

I have read several posts on this subject,but have not found any that quite answer my question.

I am in the process of installing an inline fan above my shower cubical,I have wired it from the lighting circuit via a 3 pole isolation switch, which I have situated outside the bathroom. I want to control the fan using this switch, but was wondering if I have to install 3A FCU and a separate pull cord switch. I don't want the fan to come on with the light,and I don't want timer over run.

I have used T&E cable,but the fan has a permanent live terminal for the timer,which I was unaware of when purchasing. To get the fan to run I have put a loop wire between the switched live and permanent live. Is this safe to do or do I need to change the fan,also as the fan has no earth do I terminate the earth at the fan or at the isolation switch.

Any comments appreciated

Cheers.

What make/model fan do you have? What does the instruction book say?

It was purchased from screwfix, and just has inline shower fan kit on the box. The instruction does say a 3A fuse spur is to be fitted,but I thought I would ask as I have already fitted the a 3 pole isolator and I had noticed on a few posts that this is ok. If it is not ok can I just swap the fan isolator for a 3A FCU and use it as the on/off switch.
