I think i'd be calling this "professional judgement" Andy. The supply would be coming from one mcb in the c/unit and the only places these two "circuits" would be is whithin the three pole isolator and the cable connecting the isolator to the fan. It's not as though the two circuiuts are supplying different pieces of equipment is it. I suppose this is all hypothetical anyway if no one makes a three pole isolator with two fuses!

Not arguing with what you're saying Andy, it's just the way I see it,

OK - so by the same token then Dave, the whole house comes from a single cut out fuse, so that's just one circuit as well then. After all it's not as if the consumer unit MCB's are supplying more than one house is it -

My advice - don't go there


Dave.

Yes that would be another method Dougie provided the bathroom lighting could be seperated from all the other lights, not usually practicable except on a re-wire or new installation though,

Would the whole upstairs lighting circuit need more than 3A - I seriously doubt it in a modest domestic
