Investigating a faulty fan, I found power to the junction box above and the switches inside. :D
But no joy unless I move the negative cable to the earth terminal, inside the junction box, then everything works. The isolating double-pole switch on the worktop seems to be wired correctly.
Thinking that the inplications are faulty earth I have disconnected the unit.
Anyone any ideas? :?:

get a local sparky in just to trace the wiring and then he can connect it up properly and put your mind at rest cause it will be wired correctly and safely.

You have lost the neutral will guess faulty isolator switch but this could easy cause danger and you will be better calling a spark.
