Hi Guys
I went to change an extractor fan in the bathroom today which runs off the light switch. I thought I'd isolate the power upstairs using the upstairs lighting MCB. I always double check there is no power there by switching on the lights and using my fluke to test for voltage and all the light still work? Would you say I have a defective MCB on the main board?
Cheers
Paul
