Integrated Fan & Shower Light

[BuckRogers]

Fitting an integrated shower light and fan, 12v, transformer in the loft.
There will be other downlighters in the bathroom also.
Shower light will have a switch on the wall outside the bathroom, the others a dimmer (using MK Gridplus).
Does the showerlight/fan need a seperate isolator, or does the switch serve the purpose?

Thanks in advance for your help.

I guess this is one of the in line fans that go in the loft?

If so then you should put a 3 pole isolator switch adjacent to the fan in the loft. That will allow someone to work on the fan without having to turn off the lighting circuit (thats the one that will probably power the light in the loft!).

PS do not forget the work you are planning in a bathroom has legal implications (Part P) and you'll need to be installing an RCD on that lighting circuit to meet the requirements on BS7671 (2008).

Thanks Taylor. I will do as you say re the isolator.
RCBO on the lighting cct should satisfy regs as well as avoidance of nuisance tripping?
Work needs to be notified.

Thanks again for your help !
