Hi I'm wondering if someone can help. I wanted to put up some shelves in my kitchen so I used a wall voltage tester to see if there was any live cables behind a wall before drilling and it showed none (I know the tester definitely works).
When I was drilling a spark came out of the hole and tripped an mcb in the comsumer unit which powers the fridge, washing machine, dishwasher and hob. I dug into the wall and found I had gone straight through a cable twin and earth cable. So I repaired it using a maintance free box. When I turned the tripped fuse back on everything in the kitchen works again.
However the cable I repaired has no live coming through it as I tested it with both my wall tester and my TIS 851 Voltage & Continuity Tester. It has continuity between the neutral and earth but doesn't if I turn off the main consumer unit switch.
What I'm trying to figure out is, is it possible that it is not live and tripped because when drilling the neutral and earth like this guy explains in this YouTube video...
Any help or advice would be very much appreciated. Thank you!
