Bathroom fan trips circuit breaker Ask questions and find answers to many subjects relating to electrics and electrical work

[psychocandy]

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
same...

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).

Hi PS. no it aint!
look at sw. agn. bet your N term is marked Common or C !
Use C for Live in & L1 for sw. live out , put blks in seperate chock blk in sw. box, L2 not used as only for 2 way sw. ie in bedrooms ect. Also for info this is not legal DIY as in bathroom, see DOC's part-p project info.
