The mystery of the recent spate of RCD trips and strange scratching sounds from the loft appears to be solved if not resolved. I unscrewed a panel and found a nest made out of roofing and loft materials. I also found a severely nibbled cable - whatever it is has sharp teeth.
The obvious cause is mice or squirrels, I'm not sure which. I toyed with the idea of disabling the RCD but decided that was a little reckless
Having discounted electrocuting them and borrowing a passing cat to post down the eaves we're trying what is politely called rodenticide. If anyone has any other tips I'd welcome them.
