RE: Re: LD10 and "buzzing" fuse at the consumer unit

[Keith Doxey <ukha@xxxxxxx>]

Didnt notice the bit about the main fuse.

Is it an actual FUSE or an MCB (Miniature Circuit Breaker)?

Fuses shouldnt really buzz, if it is then maybe it is aging and the fuse
wire is rattling to the surges through it just as light bulb filaments
"rattle".

MCB's could well buzz slightly as they have a coil in there that gerates a
magnetic field proportional to the current flowing through it. When the
field is strong enough, ie, there is too much curent flowing, the pull of
the field is enough to operate the trip.

Yes, I did mean loft insulation.

Thanks Kenneth however the buzzing from the LD10 was not really my
concern, it was more the buzzing from the actual main fuse for the
lighting circuit at the main consumer unit.
