The consumer unit is in a hallway, and you could hear the buzzing noise throughout the whole of downstairs. So not only was it annoying to anyone else in the house, it was also a concern to us because as afar as I’m aware, a buzzing from a consumer unit that is clearly audible from some distance...

The brand is BG

ah ok, that makes sense. Like a tug of war between the spring and magnet With neither one being strong enough to overpower the other.

I different contractor attended yesterday. Tried yet another MCB, the buzzing was still there. They said it's a 10mm cable (not 6mm), and that the MCB was probably getting close to it's limit (40amp MCB, shower pulling between 37-39amp) and causing some kind of vibration. The vibrating stopped...

It took him three weeks to come back and fit a new MCB because they’re only allowed to order parts from their selected supplier and couldn’t use the screw fix around the corner that had one in stock. I’ve already done the screwdriver trick myself, it’s definitely the mcb that buzzing. I’ve...

I'm sure it's the MCB, and the electrician thinks it's the MCB as well.

Thanks John. Do you know anything that would cause a buzzing coming from an MCB?

In a new build, we have a 9.5kw Mira shower connected to the consumer unit via a 40amp MCB and what looks like 6mm cable. When we use the shower the MCB in the consumer unit makes a buzzing noise. The builders have sent out an electrician to look at this three times now. The first time they...

The cable runs through the kitchen ceiling, and is pinned to breeze blocks, with dot and dab boarding over the top.

Type of wiring says 'A'. I couldn't find anything relating to installation method

Thanks, it says 6mm

I don't know for certain (I'm not an electrician), but I believe it's 10mm. The cable is stranded rather than a solid cable, which I think might indicate 10mm. It has one of these in the consumer unit; https://www.screwfix.com/p/british-general-40a-sp-type-b-mcb/66432?_requestid=303071 Which...

We have an EICR done a few weeks back. One of the items marked as a C2 on the report was "Insufficient overload protection" on the oven/hob circuit in the kitchen. I'm wondering what sort of thing would cause that? For context, we have a regular integrated oven/grill, and a separate glass...

Thanks for the confirmation.

Yes, it would be good if we could keep the topic of this thread based on the questions in my opening post please.
