The problem was the master C/B was loosely wired and the heat built up to an explosive level.....it could have burned down the whole 30 storey building. I changed all the C/Bs in the box for better quality and double-checked the security of all the wires.[/QUOTE]You must sleep much better at night knowing there's only another 29 floors and however many other apartments there are on your floor with faulty wiring ready to self-ignite?! At least when it all goes up you can stand next to the pile of cinders with a self-satisfied grin and say "that wasn't my wiring".
