Adding an extractor fan off of a 6A lighting circuit.
Installation instructions specify a local isolator (as I would anyway) so 3 pole isolator will be used.
Switching L SL and N however should I have an FCU upstream of the live?
It would be 6A fused as specified which seems pointless the RCBO will trip before the fuse.
Also if you fuse the live feed the Switched live to the fan is still connected even with the fuse pulled.
I think the 3 pole isolator achieves all I need to re regs and the whole circuit is protected by a 6A RCBO.
