[QUOTE="ProDave, post: 443193, member: 6969"] We have had this discussion before. BS7671 does not require a fan isolator. There is some industrial legislation that requires a "motor" to have local isolation. Now you can understand that so the guy changing a drive belt on a big motor does not lose his arm when the motor starts up automatically half way through the belt change. It is my belief that someone has applied this industrial rule, to a poxy domestic fan motor, that is unlikely to be anything more than "ouch that hurt a bit" even if you stuck your finger in the blades while running. Electrically isolating it for maintenance is no different to say a loop at light, ceiling rose, you isolate at the consumer unit. I don't fit fan isolators in rental properties because there is a long history of the tenant turning the fan off because it is noisy and then complaining about damp and mould. I still await someone telling me exactly what legislation people are applying when they fit a fan isolator to a domestic fan. Nobody could tell me that last time we had this discussion, so will someone try this time? Until they do, I regard domestic fan isolators as optional. [/QUOTE]
