Extractor Fan Rules & Regs

bert · 2015-07-01T14:55:37+00:00

The landing at the top of the start is enclosed and gets very warm this weather so I want to install an extractor fan in the loft above. NO bathromm/shower/toilet, no water involved at all. So do I "need" all this performance with triple gang switches etc or can I simply wire it through an on/off switch. I could take power from the upstairs lighting circuit quite easily or alternatively there is a redundant immersion heater supply I could use. I'm thinking of using a 100mm Manrose MF100. Any comments or alternative suggestions welcome

Thank you for the info. Was this written before head torches became widely available? Does this also mean ceiling fans should not be installed or maintained at night? What if the fan is not supplied from the lighting circuit and so on :-)

Then that is easy - use a plain DP isolator.

But it is a lot of old bollocks. They might as well say "DP isolator on every lighting room circuit in case you want to change a fitting at night, by the light of another fitting".

Boilers I can understand - gas fitters might be in those every year and would like to know the whole thing is dead.
