A customer had lost power and needed someone to urgently attend. After the usual questions I opened the fuse board and saw the melted plastic under the RCD. They said could smell something, and upon closer inspection the busbar hadn't been caught inside the RCD but instead had been only touching the clamp. So over time the poor contact had caused overheating and burnt out the RCD. Stay safe everyone 👍🏻
