Burnt out MCB on Fuseboard

Was working in a house in Dalkey today. When I opened the fuse board to check connections, I found two badly burnt MCB’s and one wire had completely burnt through. Luckily the house did not catch fire. I replaced three MCB’s and remade off some of  the cables. I also found three other very loose connections. If you have an electrician working in your home or office ask them to check the connections at the fuse board.
