I saw this today and I thought about a breakdown I had last week on an AC unit.

Customer said ac unit had simply stopped working. I found the mains power at distribution point ok, no tripped circuit breakers, but no power at inlet to outdoor unit. Cabling was long and through recessed ceiling........but i was lucky. At the cored out access hole ( external wall) the hole was left unfilled, a mouse had got in, chewed the .25mm cable, ate a chunk of insulation....the live wire was chewed , .....the mouse was still on top, very dead.

What I want to know is, Why do mice chew through electric cable, why did he eat the insulation?

AA may discount that mice posed a danger.......Going along my experience, I think they pose a very real danger.
