Whilst ironing the iron suddenly went off - I thought the MCB in our fusebox had tripped. But when I checked it, it hadn't tripped, but was crackling and there were small intermittent small sparks i could see within it. There was also a smell of ozone in the basement where the fusebox is situated. Can/should I replace this MCB myself, or should I call in a professional?
It's a 30amp MCB on a circuit supplying approx ten 13 amp sockets (plus some sockets on extension leads) in upstairs bedrooms. We have occasionally noticed some flickering on bedside lights plugged into these sockets, but not recently.
I did manually trip the MCB myself earlier in the day, as I was turning off another circuit for other reasons - it is since reseting it that I have noticed it sparking and the smell of ozone. The circuit is currently switched off, but we could do with the sockets back in use.
