Hello,

We are going to replace the bathroom extractor fan with one with a over run timer so we don't have to leave the light one to extract after a shower.

The extractor is ceiling mounted and ducted to a vent in the soffit. I'm going to replace this with an inline extractor.

A few questions.

- a assume a double insulated single core wire going from the pull cord light switch to the extractor is the correct thing for adding the permanent live required to the new extractor?

- I was going to add an isolation switch. My original thought was to add it in the bathroom in the appropriate zone (not sure if that's a UK thing) but nearly any video I see, people add the isolation switch in the attic. I thought in the bathroom would be handier as I'd the overrun failed to turn off at some stage, you had a way of stopping the fan without going into the attic. Where is the best place to put it?

Any other tips or feedback if you've done a similar job would be appreciated!
