Inline Extractor Fan - Timer wiring

[jeli]

Hi all,

 

I am going to install a bathroom inline fan with timer. The room has never had any powered form of ventilation.

 

The bathroom has a simple pull cord, where there is a permanent live to what then becomes a switched live when on and an earth.

 

The bathroom light has neutral, earth and switched live. No permanent live as you'd expect to find.

 

This house has the lowest pitched roof and access on the loft is like playing twister on your own = not fun! I haven't found any junction box for lighting, having taken a couple of boards up. Taking a break from it but a few more to go.

 

First of all, is it acceptable to take the permanent live from the pull cord and then the neutral, switched live and earth from the bathroom light? This would be the easiest route to a new isolation switch on the outside wall. Then run cables from isolation switch back to the fan in the loft.

 

When 'borrowing' a permanent live, should anything else be done? Terminate other cables in the twin core and earth with wagos?

 

Thank you for your guidance on this.

No issue with what you are suggesting.  Sometimes the permanent live is wired to the switch, sometimes to the fitting / ceiling rose.
