Hi I had a sparky wire an extractor in a new bathroom with an isolator switch outside on the landing. I couldn’t understand why sometimes it worked and sometimes it didn’t!
I removed the fan returned it to Toolstation and fitted a replacement and still the same.
I checked the wiring in the switch and the permanent live was wired to L1 and the switch live to L2 whereas YouTube videos showed the opposite. I changed them around but no difference.
I turned the bathroom light on and had a lightbulb moment literally.
I was under the impression that the isolator switch alone drive the fan and not the light pull cord too - how embarrassing
All is working now however which wiring is correct? Permanent to L1 or L2?
Thanks for your patience.
