Buzzing mcb

Handyman · 14 Jan 2004

My consumer unit must have heard it was going to be replaced, because one of the6A (Lighting circuit) mcbs has started buzzing slightly. Does this indicate a dodgy mcb? Or is it just on the point of tripping? (They are F&G mcbs - whoever they are).

faulty mcb. although, it may function prefectly it will eventually burn out.

Thanks.
In fact, another has already burnt out about 4 months ago.
Looks like my planned CU replacement is timely.
