The power went out in our office.
We called an electrician who found this in the switchboard:
The whole board was replaced when we altered two years ago.
The electrician found some of the what-nots (for which there is a technical term which escapes me as I type) needed tightening – some because they can come loose over time, some because they’d never been tightened properly in the first place.
Friends lost power recently and the cause was also found to be due to over-heating in the switch board.
The Fire Service reminds us all to check our smoke alarms when the clocks go forward and back (mutter, mumble, forward this weekend, which is at least three weeks too early). It would pay to check switch boards at the same time.
