Bathroom mirror wiring wrong?

[Jim]

I have a new bathroom mirror with lights which works ok but makes a constant buzzing noise whether it is turned on or off.

It wasn’t installed by me, but when I remove the front I was surprised to see that it has been wired using 2 electric wires - see attached photo.

As a complete novice I was wondering whether this was correct and perhaps this was the reason for the constant buzzing?

Would appreciate any help please.

Agree but do we know for sure? if it's a loop feed as you suspect, where is the loop going?

The cabinet on the other side of the wall? The next room along? The loft?

Who cares

Transformer casing is Loose and may need spray lacquer or hot glue to stop buzzing if new mirror replace.
the wiring is not the problem

Not being funny but how do you know?

We don't even know if there's a transformer there at all.

there's a lot of exposed copper in them terminals ( or should it be termini.? ).

Connections, Tel Connections, or Connecti, you could be onto something.

Thanks all, really appreciate your feedback, and reassuring to know it’s not the wiring.

Yes there is a shaver socket, which we’re never going to use, as well as a motion detection on/off switch for the light.

Nothing in the 1 page instruction manual with those logo’s. Reluctant to take off the front again this evening, it’s a pain in the soandso to get on and off!

The make is Opticon. It’s a replacement, the first one had Bluetooth and was terrible, we swapped after a week for the basic version but it’s also making buzzing noise. Relatively cheap, I guess you pay for what you get in life, but otherwise it looks great and I have to be fair, the customer service has been very good on swapping the 2 items.

Maybe I need some of this hot glue you mention. Can I buy from BBQ?

That’s hot sauce from BBQ - Hot glue from B+Q - it has a gun that you feed the stick into. You’ll use it for other things so always good to have one!

If you are not going to use the shaver socket it may be possible to disconnect the transformer without affecting the light, as it is almost certainly the transformer that is humming.

I’ve put a rated switch in-line before now. No transformer needs to be on permanently. They do ones that switch on with load I believe, which is what should happen.

Loose wires cause buzzing.

 

[DPG]

There will be a receiver module for the sensor which switches the light on and off. Could be this that's buzzing. Have a listen with the cover off (carefully obviously ) and see if you can locate the source.

As above, if it's the shaver socket transformer then disconnect it. But obviously do it whilst power is off. And don't leave bare wires.
