single voltage shaver socket

[izzy eckerslike]

Why are shaving sockets seemingly only made in dual voltage?
I want to fit a single voltage shaver socket in a standard square pattress, don't want a cumbersome dual voltage with bulky transformer that won't fit where I want to put it but can't seem to find one in local diy stores .

I take it that it is for use in a bathroom? You can get single patress non-isolating ones which are NOT for use in a bathroom.
The double sized ones have an isolating transformer behind them making them bulky, probably why you don't come across more compact ones.
Once they are supplying a transformer it is only another tapping which creates the 110v side so isn't much additional cost.
If you really hate the idea of the socket then maybe have a look at mirror units and lights with built in shaver sockets?
Also please note that adding to a circuit in a bathroom is notifiable under part p (England/Wales) if it falls into any of the zones as defined by the 16th edn regs.

The transformer is there to create an isolated supply for the socket, so that if someone touches one of the contacts, they don't get an electric shock.

They are all dual versions, as the cost difference between making a single voltage transformer and a dual voltage one is probably zero.

If you want a single plate socket, the solution is to fit a separate isolating transformer elsewhere and connect the socket to that.
You could fit a normal socket outlet, but it will need to be at least 3m away from the bath/shower. Not usually possible unless your bathroom is massive.

a shaver socket will still have a transformer even if it's single voltage.. it's to isolate the output from the input...

That one doesn't which is why it clearly states:
"Not Suitable for installation in bathrooms or washrooms"

didn't notice that bit.. well done..

the 16th edn regs.

I fink you mean 17th.

Nah, the zones are still defined (in law) using the 16th edn regs which you'll probably agree is crazy.

Thanks for the info guys, the shaver socket is for a small room with just toilet & washbasin but presumably it's still classed as a bathroom ?

 

[ColJack]

ah well then, no it's not..
it's a WC..

a bathroom has to have a shower or bath to be defined as a "special location"..
no bath or shower means you're free to put 13A sockets in there if you want..

You can put anything in there as long as it is suitable for it's intended purpose i.e. you should not put a socket or a shaver socket close to the sink so that it can be splashed nor close enough so you can drop the shaver in the sink with it plugged in, common sense really.
