Buzzing Shaver socket

[Taylortwocities]

Shaver socket transformers tend to have poor regulation. If your toothbrush is marked 100 to 250v or similar plug it in to the 110v side. There will be less strain on it that way.

But the charge base will not be

marked 100 to 250v

If it is a UK device it will be marked as 220-240VAC.
It is a simple induction coil inside the base, no fancy electronics, nothing. Its like a transformer.
Look it up on Wikipedia, if you dont understand the concept.

If you plug a regular UK (eg Braun) toothbrush into the 110v output of a shaver point then you are not going to charge that toothbrush up, not in a month of Sundays.

I suggest you look at a few toothbrushes and shavers sold in the UK. Both my toothbrush and shaver charge bases (Philips) bought in the UK are marked 100 - 240v and charge perfectly well in the 110v outlet.

My Braun ( made in Germany ) is labelled 220 - 240 ac and the same model does NOT charge in a US 110 volt socket.

You may find the time to charge is dependent on the voltage in some of the cheap end far eastern products sold as suitable for 110 - 240 volt supply.

My Sonicare (Dutch company, product made in China) is likewise.

I plug it into a non-transformer shaver socket.

I tried to fit the Crabtree sockets but found that they were too deep for the box. So, with some trepidation, I bought some more MK ones. The first thing that I noticed was that they now have a toothbrush icon on the front under the electric shaver face.
The one in the bathroom is lovely and quiet. Unfortunately, the cowboy who fitted it only pushed a 25mm long 3,5mm screw into the lower mounting hole. Off to screwfix tomorrow to buy some 40mm and 50mm ones.
The one in the en suite still hums (50Hz) when the toothbrush is plugged in, though not as loudly as before.

So the installation in the en suite makes more noise than the bathromm with both the 10 year old MK sockets and the new ones. The wiring looks fine.

Bearing in mind that it will only ever be on when the light is on, is it safe? And why is it doing this?

They at 10 year old MK shaver sockets.

Replace the socket before it overheats and cracks across the front. A common problem with that brand of shaver socket.

Thanks. Those are what we have. We have just been out and bought two Crabtree ones to replace them. Hopefully, these are better!!

Faulty. Take it back.

I have just put the quiet socket from the bathroom into the en-suite and it is humming just like the other one did!
However, if you press the front plate, the noise reduces!!!
