IMO, too - but people seem to get very literal in their concerns about failing to comply with MIs, even when there is no particularly good engineering (or, sometmes, even common sense) basis. 3-pole isolators for fans is probably as good an example as any - we've seen electricians moaning that they 'have to' fit them 'because of the MIs'.

This is another prime example of the difference between you living in your theoretical engineering world and the rest of the electricians who work in the real world and have direct relationships with their customers.
The frustration, you call it moaning but then you would, is trying to explain to customers why there needs to be this additional equipment and therefore cost in the fan circuit.
The reality is that 134.1.1 is available to all manufactures to minimise their sale of goods act responsibilities so they will use it - and so we must follow.
But your response also re-enforces the view of a number of people on this forum that you believe you are the final arbiter of what makes good engineering and sadly what makes common sense.
The latter of which you don't practice - because you would have taken your own advice and left on the 28th January 2012 as you promised.
The questions raised on this forum are invariably from diyers or amateur electricians who want simple solutions to their problems.
In nearly all cases there is a simple answer - that is until you put your three penneth worth in - after which confused reigns and we're off on some rambling philosophical diversion to satisfy you own needs.
The OP has long since departed, probably jumped of a bridge (FFS I only wanted to know how to wire a fan circuit
) Leaving only your fawning sycophants to post 'Thanks' at every opportunity.
As I have said in the past I come on this forum to try and help diyers with their problems (or tell them they're out of their depth) and at the same time learn from other electricians who have experienced problems that I may come across myself. Its a sad fact that you are slowly destroying this forum by hijacking posts to meet your own ends.... whatever they are.
