Downlights & Extractor Fan

[m4tty]

Hi,

Ive got a bathroom to do and wanted your advice on the best way to do it.

At the moment theres just a single pendant with a pull chord. Ive got to install 4 downlights and an extractor fan. What I planned to do was install a maintenance free jb in place of the ceiling rose and run the downlights from this. Also running the extractor fan from this too. The studwork for the new drop ceiling has been fitted about 6 inches from the old ceiling.

Will I get all the cables in 1 maintenance free jb?

And will a switched fcu (3a) be ok for the extractor fan or does it need a triple pole isolator?

Thanks in advance for any help.

Cheers

Hi

Depends how you want to control the fan, if no window then normaly linked to come on with light so you need 3 cre to timer fan via 3 pole isolator.

If you loop from light to light then you should get all required cables into 1 JB.

If your feed and switch wire will reach to one of the down light positions then I normmally make that the JB position and if you use a small 20 Amp JB it can always be accessed thru a down light hole.

If fan requires 3A fuse then all line cables need fusing to 3A so easiest way is to run both the lights and the fans off a 3A fcu first then off to the switch and back to the downlighters and the fan isolator and onto the fan.
