[Adrian Settle]

Hi
I have just put 9 5.5w = 40w led bulbs in 3 lights 2 are on dimmers & when they are turned on the main fuse box starts buzzing is this bad & do I need to remove bulbs.

If you turn the lights of does the board stop buzzing as the usual culprits are the switches if they can't handle LED's

Yes m8 it's stops & also stops if I dim them it's either bright or dim no inbetween

Did the LED's state that they are dimmable?

No they didn't but why would they make the circuit board buzz

If you have fitted non dimable led lamps, and you are dimming them, that's not good for the lamps, the dimmer or the mcb's .....

The MCB has an electromagnetic coil inside as part of the overload protection and the dimmer switch can cause harmonics into the circuit causing the mcb buzz.

Remove the dimmer, add a normal switch or join the two cables together and see what happens if the noise stops then you know its either the dimmer switch or the lamps causing the issue, I had weird issues with non dimmable lamps someone installed, they had life of their own.
