I used the table saw in my 'workshop' at the bottom of the garden on Saturday for the first time in a while. I pressed the ‘start’ button and within about a second everything went dark and quiet.
Local 20A MCB feeding the ring final in the workshop was not tripped, and neither was the RCD in the workshop board.
So I head back to the house to be greeted by House Management declaring that the power has gone off. Nothing tripped on the CU in the house either, and the Smart meter was dead, so a call to UKPN followed. All neighbours still had power.
The lucky part was that UKPN were working 15 doors down the road on a more serious cable fault affecting a property and they sent a nice chap round to replace the 60A fuse in the service head - all fixed inside 40 minutes from going off.
The load in the rest of the house at the time was minimal - no ovens, kettles, toasters, washing machines or tumble driers etc. running - just the fridges, routers etc. and House Management's TV.
I know the table saw has a bit of a surge current on switch on, but I'm guessing I just got unlucky that discrimination didn't really work out for me this time and the service fuse went pop.
Further operations of the saw caused no further problems.
Any thoughts on any other causes - other than bad luck?!
