Good call!or the FCU could feed the bathroom light as well, so both would be fused.
Yes he is quite good isn't he? LOLGood call!

Ooh i love a mass debate! There is no requirement unless the manufacturer specifies it, i rarely fit an fcu, just the tp fan isolator will do in my eyes. The fcu would only be needed for the permenant live as that is what runs the fan motor, the switch live is just to trigger it if its a timer fan that is! If its not a timer fan then just an fcu would do the job as there would be no permenant live anyway!To stir up some debate ....... dont you have to 'fuse' all the live conductors to the fan? (the way Tel suggests does this!) and unless the manuf says so, where is there a requirement to fit a specific fan isolator? (setting aside good practise!)

it's good practice to fit a fan isolator when there is no window to let in natural light to see when working on the fan.
Head torch, you shouldn't work on lights when they are live :biggrin5:That old cookie! So what do you do for 'light' when working on the light(s) in the bathroom ......
Manrose how about you? They specify a 3a Dp fused spur before the light switch so like tel said the whole lot would be on the fcuReally - which fans do you fit?
Ooh i love a mass debate!
