When you turn it on using the pull switch the RCD switch (for upstairs
lights) trips on the consumer unit.
I've changed both the fan and the actual pull switch but still the
I've even disconnected the fan and the switch itself sets it off....
Any ideas ???
Basically, the switch has got a terminal for N (so I attach both black
wires to this), and a live 1 and live 2 (to which I attach one each of
the red wires).
