Buzzing Hager consumer unit

Perhaps the lighting circuit is overloaded, just a thought or get a sparky to check the connections or change the MCB for a new one to see if this makes it less noisy.

 

Assuming that you've checked the soundness of all connections - including Neutrals, and assuming that the buzzing doesn't happen when there's no load connected: Then this is likely to be an internal fault with the MCB.  This is quite common with bottom-of-the-market cb's, but most unusual with Hager devices.
It's usually a loose - vibrating linkage between the lever and the short-circuit component.  This problem is often amplified by the presence of toroidal-type transformers for light fittings or similar 'dirty' loads. This being the case, the MCB should be renewed.

A mancunian would well understand that pish remark of yourin unphased, take care if you are amongst them with remarks such as that , you may well get a good slap.

 

What a shame that from #6 onwards the "restricted" make their pathetic appearances

 

Very dodgy ground...

 

Have you heard any news from Lucia DA?
