I have been to a boiler which has had the PCB damaged by a mains surge. This blew apart the surge supressor on the board.
The block had been converted into three flats and the electricity supplier was fitting three seperate meters to feed the three flats.
Somehow they managed to connect two phases across the supply to the flats and applying 315 vac to a surge supressor rated at 275 VAC immediately caused it to go s/c. A computer in another flat was also damaged.
I am posting a question on the electricians section about compensation claims which might interest someone.
