Is your fusebox a Wylex Standard? Is it White or Brown? If so I can let you have an MCB and shield to fit for a modest cost, it will save you time replacing the fusewire (although it will not solve the underlying problrm). You just "switch" it back on.

problem with replacement fuse wire repeatedly blowing
- Thread starter dh
- Start date
If a lighting circuit has all lamps OFF, you still have live cables everywhere! It does help to rule out items, but it could easily still be a fault behind a light fitting (loop in loop out means fittting still has live terminals when off), could be a fault on a cable to a switch...or from one light to the other.
You are now in the position to find the fault, and stop asking questions
There is a damaged cable or accessory somewhere.
Have you been drilling? Screwing floor boards down? Hanging pictures? Changind lights/switches?
Is your door bell tranny on this same fuse? Just a thought.
Bathroom get steamy or damp? Shaver point?

Ok so last room used is bathroom - having a bath or shower before going to bed?
Could be a build up of condensation in light fitting or fan
One more thing to eliminate from your enquiries - is there a TV aerial amplifier in the loft?

Two more ideas
[1] If there is a wire trapped under a floor board then it may be shorting out when some one stands on that board or sits on furniture on that board. As it is night time evening the boards under the legs of a bed could be suspect.
[2] Any wall lights that run of the lighting circuit.
And one very un-likely possibility but I have seen it twice.
[3] Is there any chance that some one has connected into the lighting ciruit in the loft to provide power to the house next door.
Once was intentional theft, missing bricks in the party wall in the loft allowed a neighbour to connect into the lights. The second was a large house converted into flats and the lights for two flats had not been properly separated.

I have seen it before where someone has bunged a load of plastic terminal blocks above a bathroom light. The heat from the lamp had caused the block to melt causing a fault, the luminaire being an enclosed type didn't help the situation.
My brother had exactly that in his shiny new build house.

Has the fan a fused connection with a flex from the FCU to the fan? Had one of these with similar symptoms, i.e. everything OK, but after 20 minutes fuse blew (Wylex box). The problem was corrosion products across the plastic. The fan was in a kitchen, under a bathroom which flooded. Fuse badly corroded so I guess the conductive path to earth was building up over time with a mixture of metal and water. Cleaned, new fuse and remade terminals. Problem gone. HTH
