Last week I was working in a house changing a socket. When I turned the main switch back on and the MCB on the socket didn't energise. I went and turned off again, checked all connections, and 2nd time around it worked for no particular reason.
I put it down to maybe turning on the wrong circuit or somehow getting confused and thought no more about it.
I got called back today, no power to hob (different circuit) . When I got there I used a plug in tester on the cooker plate and it was dead. I walked to the consumer unit turned off the MCB, walked back to the cooker plate, took it off, checked all connections (and noted the was N-E continuity) and there was nothing wrong.
Then I turned the MCB on again and it worked.
I've checked all CU connections. It's an older Crabree Starbreaker board.
I thought it was worth a post to see if anyone has ever have Starbreaker MCBs play up in a random way. Or any other random issues with the insulated bus bar.
If it happens again I think first port of call is CU and test top of breaker...
I hate it when you don't know why something starts working again!
