Wylex 6amp mcb buzzing

[Lilyrose08]

Hi all this is the second time i have come across this had to put all lights on one mcb because of a borrowed neutral.
Mcb connected correctly with torque screwdriver and conductors in tight and still getting a slight buzzing sound and not much load
On The circuit there is dimmers and trannys though is it anything to worry about or could it just be harmonics.

Prechecks, prechecks, prechecks!

Is it an MCB that was part of the product recall? If it catches fire then it was!!

Fix the borrowed neutral and spread the load?

Almost certainly due to tired, cheap, or unsuitable Dimmer(s)!! That would be my first choice anyway!! As for the shared neutral why didn't you separate, ...get it fixed!! lol!!

I bet there is a non dimmable fluorescent lamp somewhere being controlled by a dimmer. I'd stake my house on it!

Good chance.
Seen it with these eco friendly domestic designer gits who sucker householders into changing all their lamps to energy saving.....don't think to note that their new costly lamps aren't dimmable.... breakers buzzing like bees.
